Let me at 'em -- again! SCS returns to the cage to whup on CRT & evolution belief...

Well, the Science Curiosity Scale (SCS), having watched from the sidelines “yesterday” as CRT and AOT went head-to-head (surely not toe-to-toe) on belief in evolution got pretty restless & decided she had to climb back  into the ring—I mean steel cage—to get a piece of the action.

oooooo.... the carnage!As we all know, SCS mauled the hapless trio of Ordinary Science Intelligence (OSI), Actively Open-minded Thinking (AOT), and the Cognitive Reflection Test (CRT) on belief in human-caused climate change.

Whereas the latter three were all associated with the magnification of political polarization over climate change, SCS alone was associated with greater acceptance of it regardless of partisan identity.  It is plausible to see this result as reflecting the power of science curiosity to counteract “motivated system 2 reasoning” (MS2R), the tendency of cognitively sophisticated individuals to use their advanced reasoning proficiency to reinforce their identity-defining beliefs.

Well, SCS decided to come out of retirement & duel CRT again, this time on evolution.

As Jonathan Corbin noted “yesterday,” CRT predicts belief in evolution only conditional on religiosity. That is, it predicts greater belief for non-religious folks, but not for religious ones.

This is consistent with MS2R: disbelief in evolution being an identity-defining belief, one would expect religious individuals who are higher in cognitive proficiency to be even less likely to believe in it.

One can corroborate this more readily with the Ordinary Science Intelligence Assessment, a measure of cognitive proficiency that is more discerning than the 3-item CRT test. Because the CRT throws away information on variance for half the population, the picture is blurrier, although with a large enough sample, one can still see that the trend in belief in evolution is negative, not just flat, as it appears in the left panel here:

But anyways, it’s not negative or flat—it’s positive for SCS, as shown in the right panel.

Here's your raw data, btw! Drink up! That is, SCS, unlike CRT, predicts greater acceptance of evolution unconditionally, or regardless of religiosity (which is defined here via a scale that aggregates frequency of prayer, church attendance, and importance of religion in life).

Well, there you go: another day, another steel-cage motivated reasoning mauling at the hands of SCS!

The question is why? And who--who are these guys??

You know, I thought I “had this all figured out.” Then we just b/c someone will surely ask: the relationships between religiosity & CRT & SCShappened to take a peek at how SCS, developed to advance God’s plan (she’s got a sense of humor just like everyone else!) of promoting enjoyment of cool movies about evolution & other science topics, relates to polarized science issues.

Now I’m confused as hell all over again.

Asked & already answered: CRT & SCS relationshipGood.  If there is a hell, the suffering one is made to experience there forever isn’t being too hot (that’s just Connecticut in August).

It’s being bored b/c everything you look at comes out the way you expected.

So is AOT measuring AOT? I think so; the steel cage results don't necessarily imply otherwise

This is an excerpt from my and Jonathan aka "cognitive steel-cage match Don King" Corbin's paper on AOT and climate change polarization. I'm posting it as a follow up to my own response to @MaineWayne's perceptive question in response to Jonathan's post from "yesterday" on the grizzly AOT vs. CRT steel cage match.

he results of the study [showing that higher AOT scores magnify rather than mitigate political polarization over the reality of climate change] could be understood to suggest that the standard measure of AOT included in the data we analyzed is not valid.  Actively Open-minded Thinking is supposed to evince a motivation to resist “my side” bias in information processing (Stanovich et al., 2013). Thus, one might naturally expect the individuals highest in AOT to converge, not polarize all the more forcefully, on contested issues like climate change.  Because our evidence contravenes this expectation, it could be that the AOT scale on which our results are based is not faithfully measuring any genuine AOT disposition.

We do not ourselves find this last possibility convincing. Again, the results we report here are consistent with those reported in many studies that show political polarization to be associated with higher scores on externally validated, objective measures of cognitive proficiency such as the CRT test, Numeracy, and science literacy (Lewandowsky & Oberauer 2016; National Research Council 2016; Kahan, 2013, 2016; Kahan et al., 2012).  Because such results do nothing to call these measures into doubt, we do not see why our results would cast any doubt on the validity of the AOT scale we used, which in fact has also been validated in other studies (e.g., Haran et al., 2013; Baron et al. 2015; Mellers et al., 2015). 

Instead we think the most convincing conclusion is that the disposition measured by the standard AOT scale, like the dispositions measured by these other cognitive-proficiency measures, is one that has become tragically entangled in the social dynamics that give rise to pointed, persistent forms of political conflict (Kahan, in press_b). As do other studies, ours “suggest[s] it might not be people who are characterised by more or less myside bias, but beliefs that differ in the degree of myside bias they engender” (Stanovich & West 2008, p. 159). “Beliefs” about human-caused climate change and a few select other highly divisive empirical issues are ones that people use to express who they are, an end that has little to do with the truth of what people, “liberal” or “conservative,” know (National Rsearch Council 2016; Kahan 2015).[1]

 


[1] Science curiosity might be an individual difference in cognition that evades this entanglement and promotes genuine  receptivity to counter-attitudinal evidence among persons of opposing political outlooks (Kahan et al. in press).

Still another cognitive-style steel cage match: CRT vs. AOT go "head to head" on belief in climate change & belief in evolution

Jonathan aka "Don King" CorbinThe carnage continues! SCS (aka "Science Curiosity Scale") is taking a rest after having bashed its way to the top of the open-mindedness rankings, but this week we bring you CRT vs. AOT in a match arranged by the Don King of the cognitive-style steel cage match world, Jonathan Corbin!

If You Open Your Mind Too Much Your Brain Might Fall Out, But At Least It’ll Have a Parachute to Soften the Landing

Jonathan Corbin

Frank Zappa said, “A mind is like a parachute. It doesn’t work if it is not open” (though Thomas Dewar may have coined the phrase).  This is the motivation behind the psychological scale measuring actively open-minded thinking (AOT; Baron, 2008).  AOT is a self-report scale meant to measure the tendency to which an individual seeks out information that conflicts with one’s own beliefs.  So, simply having an open mind is only half of what this scale tries to measure – the other half is the propensity to look for information that disagrees with your current beliefs.  At first look, AOT seems like a silver bullet in terms of understanding why some people seem so resistant to scientific information that threatens their beliefs. 

Recent work by Dan Kahan and colleagues has shown that another individual difference measure – Science Curiosity – has been shown to relate to increased acceptance of human-caused global warming regardless of political affiliation.  Whereas performance measures like the Cognitive Reflection Test (which measures some combination of impulse control/inhibition and mathematical ability) and measures of scientific knowledge predicted increased polarization on politically charged scientific issues like climate change, science curiosity predicted the opposite!  As soon as I saw this result, I was immediately curious about how the AOT would do in such a comparison.  The obvious prediction is that AOT should perform just like science curiosity – an increased predilection for seeking out information that disagrees with one’s beliefs should definitely predict increased acceptance of human-caused climate change!

Dan was nice enough to direct me to his publicly available dataset in which they measured climate change beliefs as well as AOT (along with CRT, science knowledge, and many other variables), allowing us to test the hypothesis that individuals higher in AOT should be more accepting of climate change regardless of political affiliation.  As you’ve probably guessed if you read Dan’s previous post, it turns out that AOT was more similar to performance measures like the CRT, showing greater polarization with higher scores on the scale.

So, unfortunately it appears to be the case that AOT is not the silver bullet that I once thought it could be.  Perhaps, rather than Zappa’s quote of the mind as a parachute, I should be looking to Tim Minchin, who said, “If you open your mind too much, your brain might fall out.”  To further explore this pattern, I looked at another contentious topic – evolution.  Rather than examining political identification, for this analysis, I relied on religiosity (given that there is also a reason for many highly religious individuals to deny evolution as an identity protective measure).  The other reason I looked at religiosity is that there is a lot of AOT research linking higher religiosity with lower AOT.  This is interpreted as evidence that greater religiosity is associated with a heavier reliance on associative intuition (or “going with your gut”) as opposed to deliberative thinking (Gervais & Norenzayan, 2012; Pennycooke et al., 2013).  Few (if any) other studies collect nationally representative samples with such a large number of participants, so Kahan’s ordinary science intelligence dataset allowed us to test whether greater AOT in religious individuals relates to increased acceptance of evolution. 

Results show a similar pattern to the climate change question, with CRT and AOT behaving similarly in that higher AOT failed to predict greater acceptance of evolution in the highly religious.

If there is any consolation, it is that we can say that higher AOT in the highly religious did not predict decreased belief in evolution.  However, this data certainly does not give hope for the prediction that belief should increase with greater AOT among the highly religious.  Similar to political identity and climate change, whereas the overall relationship between AOT and belief in Evolution remains positive, broken down by religiosity, the picture quickly becomes more complicated.

By now, you are probably asking yourself whether there is any real difference between the CRT and AOT.  Definitionally, they are distinct (though expected to share variance), however, so far I haven’t given you much data to encourage that belief.  Well first of all, there is other research out there to support a difference.  For example, Haran, Ritov, and Mellers (2013) examined both AOT and CRT scores in relation to forecasting accuracy and information acquisition (basically what predicts how much information you’re willing to take in as well as your accuracy in predicting an outcome related to such information).  They demonstrated that AOT predicted superior forecasting over and above any effect of CRT (and this was mediated by information acquisition). 

We can also look for differences in the ordinary science intelligence dataset that we previously examined.  Rather than looking at individualls' belief in evolution, I analyzed level of agreement with the statement ““From what you’ve read and heard, is there solid evidence that the average temperature on earth has been getting warmer over the past few decades, or not?”.  This question differed from the last, in that it does not ask about agreement with human-caused climate change – it only asks if there is solid evidence based on “what you’ve read and heard”.  The data showed that there was no main effect of CRT and no interaction between CRT and political affiliation (political affiliation did predict agreement with conservatives less likely to agree than liberals).  However, AOT did show a significant relationship, predicting greater agreement.

So, where does this leave us? It seems that although AOT is likely distinct from performance measures like the CRT, it falls into the same trap when it comes to science issues that generate conflicts with individuals’ identities.  Despite the fact that AOT is meant to measure one’s propensity toward seeking out belief-inconsistent information, it fails to predict higher levels of agreement with evidence-based claims that cue these identities. 

Given the final analysis reported here (and the literature as a whole), claiming that the result boils down to measurement error is probably incorrect.  It is more likely that one’s propensity to seek out information (particularly information that conflicts with one’s beliefs) is simply insufficient in countering the strength of cultural identity in swaying reasoning.  With regards to the evidence for human-caused climate change, there is an enormous amout of information available online.  Simply see the following website for a list of arguments in favor and against human-caused climate change.  This seems to be the perfect resource for someone high in AOT.  However, a lot of these arguments on both sides are technical, and it is possible that someone high in AOT may not be satisfied with trusting experts’ interpretation of the evidence, and would rather judge for themselves.  The need to judge for themselves mixed with the desire to come to conclusions that support one’s identity could very well increase polarization (or at the very least lead to no increase in support for those who’s identities support disagreement).  (It is worth the reminder that these are post-hoc explanations that require testing).

So, is Zappa correct in that an open mind a parachute or should we listen to Minchin who says that it is a recipe for losing one’s brain?  Well, the answer (because it is psychology) is--it depends!  When dealing with non-polluted science topics you should expect a positive relationship between AOT and agreement (maybe above and beyond performance measures like the CRT).  However, once you throw in the need to protect one’s identity, AOT is not going to be the solution.  So, why is science curiosity different from AOT?  Perhaps science curiosity is less about belief formation and more of a competing identity.  Whereas AOT is focused on how someone forms and changes beliefs, science curiosity is simply the need to consume scientific information.  Maybe instead of trying to throw information at people hoping that it’ll change their minds, we should start fostering a fascination with science.

SCS vs. AOT ... latest "politically motivated reasoning steel cage match" 


So here’s a bit more on the new paper that I mentioned yesterday.

In it, Jonathan Corbin & I analyze how Actively Open-minded Thinking (AOT) relates to acceptance of (“belief in”) human-caused climate change.  AOT reflects the disposition to  seek out, engage, and give appropriate weight to evidence that challenges one’s existing beliefs (Baron 2008; Stanovich and West, 1997).

But we found that higher levels of AOT, as measured by a standard scale (Baron et al. 2015; Harat et al. 2013), magnify political polarization over the reality of human-caused climate change. 

This is surprising because AOT consists in a tendency to resist confirmation bias of the sort that would predictably reinforce partisan divisions on contested issues. So one might well have expected AOT to result in some degree of convergence, not enhanced divergence, in the beliefs of those partisans who score highest on a standard AOT measure.

As I’ve noted in some posts relating to a recent paper in the Annenbenberg Public Policy Center/Cultural Cogniton Project Science of Science Communication Initiative series (Kahan, Landrum, Carpenter, Helft & Jamieson in press), science curiosity does seem to generate that sort of convergence.  As rare glimpse of precise moment of conception of academic paper . . . click it!partisans’ science curiosity, measured by the APPC/CCP Science Curiosity Scale (SCS) increase, their acceptance of human-caused climate change uniformly increases.

Indeed, the magnification of polarization perversely associated with greater science comprehension generally is negated in individuals who score high in SCS.

Jonathan and I wanted to figure out if this was a feature SCS shared with AOT.

But in fact, the greater magnification of polarization that these reasoning dispositions manifest—a dynamic I’ve referred (or attributed) to “motivated system 2 reasoning”—seems to affect AOT, too.

So in this regard, AOT, like numeracy, CRT, and Ordinary Science Intelligence is recruited as a foot soldier in the imperial campaign of our identity-protective selves to rule over the empire of our cogntive life . . . .

Our that’s one interpretatioin. Maybe something else is going on!

But in any case, SCS alone seems to resist this tendency.

So in this sense, the paper is an outgrowth of the latest string of motivated-reasoning “seel-cage matches,” in which SCS has gone toe-to-toe, neuron-to-neuron against an all-star cast of reasoning-disposition measures and bested all of them in the search for an individual difference that counteracts the tendency of people to form and persist and beliefs that cohere with their identity-defining group affiliations.

In this ase, AOT and SCS were not in the same data set, so it was sort of a virtual cage-match. So critical, reflectiveve readers should take that into account as well in taking stock of the results.

SCS continues on its undefeated rampage in brutal cognitive steel-cage matches ... I hope everyone is wearking protective headgear! Click click click!That that into account along with all the other considerations that bear on the weight to be assigned on bit of evidence relevant to an issue or set of issues no one study or even set of studies should ever be taken to “definitively resolve.”

The advancement of knowledge consists in the permanent assimilation of all that is known without all that we may yet come to know in our assessment the relative plausibility of competing conjectures.

Now there is at least one other thing to say about my and Jon’s new paper: it’s inconsistency with the so-called “asymmetry thesis,” which posits that the incidences of politically motivated reasoning are a feature uniquely or at least predominantly associated with ideological conservatism as a personality trait (e.g., Jost et al. 2003).

More on that “tomorrow. . . .”

Does "Actively Open Minded Thinking" Aggravate Political Polarization on Climate Change? Looks like it . . . (New paper)

I’ll likely have more to say about this little (it really is little—< 2,000 words) paper.  But for now suffice it to say that I’ve fallen off the wagon and am back to the asymmetry thesis . . . . It will never let me go!

SCS vs. CRT: Another politically motivated reasoning steel cage match!

I’ve been getting a lot of questions about how the   Annberg Public Policy Center/Cultural Cogntion Project “Science Curiosity Scale” (SCS) relates to other measures of open-mindedness.

The Cognitive Reflection Test (Frederick 2005), which assesses the disposition of individuals to consciously and deliberately interrogate their intuitions, is often viewed as such a measure (e.g., Campitelli & Labollita 2010; Pennycook, Cheyne et al. 2013).

One would expect there to be a modest correlation between a measure of open-mindedness and science curiosity, and there is one between CRT and SCS:

But the correlation is only modest: the probability that someone in the top general population decile of CRT—someone who scores a perfect 3—is only 2x as likely as someone who scores zero on CRT to be in the top general population decile of SCS. 

Obviously, the two aren’t measuring the same thing.

This is a picture of the "raw" data for the figure below. Always always consume raw data before exposing yourself to a multivariate analysis--or you could end up bamboozled!They also don’t predict the same style of political information processing.

Despite arguably being the best measure of reflective thinking (Toplak, West & Stanovich 2013), CRT magnifies politically motivated reasoning (Kahan 2013).

That’s why polarization on an issue like human-caused climate change increases as CRT scores go up. As their SCS scores go up, in contrast, individuals don’t become more polarized but rather become more accepting, regardless of their political outlooks.

Here's the regression model for the last figure. If someone shows you only this when reporting his or her data, demand your money back!Indeed, the polarizing influence of science comprehension is suppressed by higher science curiosity as measured by SCS.

As I explained “yesterday,” this is plausibly attributed to the willingness of individuals who are high in science curiosity to expose themselves information that contravenes their political predispositions, something that partisans ordinarily are loath to do and that is not predicted by other dispositions, including CRT, associated with greater science comprehension.

This is one of the findings in the APPC/CCP paper “Science Curiosity and Political Information Processing,” which is forthcoming in Advances in Political Psychology.

There’s no question that the CRT measures an important species of critical reasoning.  I’d experience a degree of shock that even the subjects in the Milgram experiment would have balked at imposing were it to turn out that SCS came within a mile of CRT in predicting resistance to heuristic information processing generally.

But when it comes to predicting resistance to politically biased information processing, SCS picks up on an individual difference in cognition that evades CRT.

Cultural cognition of weather: a cool (or warm) guest post!

And now for something completely different-- a guest post from someone who knows what he's talking about! (And is this just my politics speaking or was July really friggin hot?!)

Cultural Cognition of Weather
by Larry Hamilton
Carsey School of Public Policy, Univ. New Hampshire

December of 2015 was the warmest ever recorded in New Hampshire, by far. Indeed, in temperature anomaly terms (degrees above or below average) it was the warmest of any month for at least 121 years. January, February and March of 2016 were less extreme but each still ranked among the top 15, making winter 2015–2016 overall the state’s warmest on record — eclipsing previous records set successively in 1998, 2002 and 2012 (Figure 1).

Seeing in this record a research opportunity, colleagues and I added a question to a statewide telephone survey conducted in February 2016, to ask whether respondents thought that temperatures in the recent December had been warmer, cooler, or about average for the state. Two months later (April), we asked a similar question about the past winter as a whole. Physical signs of the warm winter had been unmistakable, including mostly bare ground, little shoveling or plowing needed, poor skiing, spring-like temperatures on Christmas day, and early blooming in a state where winters often are snowy and springs late. Not surprisingly, a majority of respondents correctly recalled the warm season. Their accuracy displayed mild but statistically significant political differences, however. Tea Party supporters, and people who do not think that humans are changing the climate, less often recalled recent warmth (Hamilton & Lemcke-Stampone 2016). Although percentage differences were not large, these patterns echoed greater differences seen in studies that asked about longer-term changes. Our February and April surveys had found counterparts on a much more immediate, tangible scale.

Fig. 1

Although the February and April 2016 results fit with broader patterns, they were not overwhelming by themselves. Believing in the value of replication, we asked the question one more time on a July 2016 survey, with winter several months behind. Most people still recalled the unseasonable warmth. Our July wording and results are as follows:

Thinking back to earlier this year, would you say that THIS PAST WINTER, the weather where you live was generally colder, warmer, or about average for winter in your area? ROTATE 1–3

1          Colder than average winter for your area (4%)
2          Warmer than average winter for your area
(74%)
3          About average winter for your area
(18%)
98        DK/NA (4%)

Political and climate-belief gaps now appeared wider than they had been earlier in the year. Figure 2 shows one striking example: a 21-point gap between supporters of Clinton and Trump (this was, after all, primarily a political poll).

Fig. 2Figure 3 breaks down the percentage of “warmer” responses on the July survey by other respondent characteristics, including their beliefs about climate change. P-values summarize tests from probability-weighted logit regression.

Fig. 3One notable pattern in Figure 3 involves political identification; we see a 17-point gradient from Tea Party supporters to Democrats in recollections about the winter they had all just experienced. Climate-change beliefs produce wider differences: respondents who don’t believe that climate is changing, or that climate is changing but for natural reasons, were much less likely to recall the warm winter.

Figure 4 places this July poll in context with political gradients (using the same 4-party scheme) from five previous surveys that asked longer-term climate/weather questions. Panels (a) and (b) involve atmospheric CO2 levels and Arctic sea ice (Hamilton 2012, 2015). Panels (c) and (d) depict results from two Northeast Oregon surveys that asked whether summers there had become warmer in the past two decades (Hamilton et al. 2016). Panel (e) charts responses to a question about whether flooding in New Hampshire had increased over the past decade (Hamilton et al. in press). Panel (f) repeats the unpublished July survey results described earlier, on whether New Hampshire’s recent winter had been warm.

Fig. 4What underlies this replicable pattern? Atmospheric CO2 levels and Arctic sea ice are not directly experienced by most people. They are measured and communicated mainly by scientists, so public resistance to these well-observed realities might be conceived as a problem of science communication, highlighting the need for ideologically-tailored methods. But science communication on these topics already involves many different organizations, research teams, and individual scientists taking diverse and ofttimes innovative approaches. An alternative hypothesis is that the partisan gradients reflect not shortcomings of science communication but the efficacy of counter-science communication, convincing ideologically receptive audiences that undisputed facts are false. The sociological literature about such counter-messaging has recently been summarized by Dunlap and McCright (2015).

Science communication seems distant, moreover, from panels c–f, which involve phenomena that can be directly experienced. Warmer, dryer summers in Northeast Oregon have exacerbated insect and disease threats to forests, both directly and indirectly contributing to the frequency of large wildfires. Such changes are visible, and in isolation seem equally compatible with individual beliefs that climate is change is happening either for natural or anthropogenic reasons — which together comprise 85% of the respondents in both Oregon surveys. Nevertheless, we find steep political gradients. Similar observations apply to flooding in New Hampshire, which has caused significant damage, and is most salient not through scientific reports but through news coverage if not personal experience. Again, most news coverage made no explicit connections with climate change, and most people (89% on these surveys) agreed anyway that climate is changing, whether from human or natural causes.

Although wildfires and floods might not impact everyone, or impress them with decadal change, the snowiness or un-snowiness of a winter affects daily life for just about everyone living in New Hampshire. Panel f depicts ideology-influenced perceptions at the mundane scale of recent weather.

Science curiosity vs. politically motivated reasoning: An experimental steel cage match!

So today I’ll finally tell you what we did in the information-seeking experiment featured in our new paper “Science Curiosity and Political Information Processing.”

It was pretty darn simple.

We assigned subjects to one of two conditions. In each, subjects were presented with two news story headlines: a “climate realist” one, which announced that scientists had uncovered evidence consistent with human-caused climate change; and a “climate skeptical” one, which announced that scientists had uncovered evidence that qualified or called into question the human contribution to climate change.

The difference in the conditions concerned the relative novelty of the opposing pieces of scientific evidence being featured in the respective headlines.

Thus, in Condition 1—“Realist unsurprising, Skeptical surprising”—the  respective newspaper headlines were “Scientists Find Still More Evidence that Global Warming Actually Slowed in Last Decade” and “Scientists Report Surprising evidence: Arctic Ice Melting Even Faster Than Expected.”

In contrast, in Condition 2—“Realist surprising, Skeptical unsurprising” condition—the respective headlines read, “Scientists Report Surprising Evidence: Ice Increasing in Antarctic, Not Currently Contributing To Sea Level Rise” and “Scientists Find Still More Evidence Linking Global Warming to Extreme Weather.”

Subjects were instructed to “pick the story most interesting to you,” and told they’d be asked some questions after they finished reading it.

Aversion to “counterattitudinal” information—that is, information that is contrary to one’s political outlooks—is one of the incidences of politically motivated reasoning.  When given the option, partisans tend to seek out information that is consistent with their predispositions rather than information that is contrary to them (Hart, Albarracín et al. 2009).

That’s exactly what we observed among subjects who were relatively low in science curiosity.

Among subjects who were relatively high in science curiosity, however, we saw the opposite effect.  Thus, relatively right-leaning science-curious subjects—who tended to be climate skeptical—nevertheless preferred the novel or “surprising” realist news story over the unsurprising skeptical story.

Likewise, relatively left-leaning science-curious subjects—who tended to be climate concerned—preferred the surprising skeptical story over the unsurprising realist one.

The effect sizes, moreover, were quite large: moderately science curious subjects were on average 32-percentage points (± 19, LC = 0.95) more likely to select the story that was contrary to their political predispositions than were moderate science incurious ones.

We are motivated to investigate this hypothesis by an unexpected observation in our “science of science filmmaking” studies.  As subjects’ science curiosity increased, their perceptions of contentious risks tended to move in the same direction. Moreover, high-curiosity subjects seemed to resist the normal tendency of individuals to polarize as their proficiency in science comprehension increased. 

We surmised that these individuals might be indulging their appetite for surprise by more readily examining evidence that contravened their political predispositions.  Being exposed to a greater volume of “counterattitudinal data,” they’d form views that were more uniform, and less prone to polarization conditional on science comprehension.

The experiment results supported this hypothesis.

Does this “prove” that science curiosity negates politically motivated reasoning?

No!

It’s a mistake to think empirical evidence ever proves anything

What it does, if it is the product of a valid design, is furnish more reason than one otherwise would have had for crediting one competing account of some phenomenon over another. 

As I explained yesterday, the hypothesis that that science curiosity offsets politically motivated reasoning, is a plausible conjecture—but so is the hypothesis that science curiosity, like other cognitive elements of science comprehension, magnifies this biased form of information processing.

On the scale that registers the strength of the evidence for these respective hypotheses, the experiment result puts an increment of weight down on the side of the first hypothesis.

How much weight?

Well, you can decide that!

But if you are curious for our own views, read the paper: It catalogs our own qualifications and sources of residual uncertainty—and outlines a set of questions for further investigation.

We’re really curious to see if this result stands up to even more critical testing!

Science curiosity & politically biased information processing--the (inevitable!) OCTUSW response

OKay, yesterday I promised to say more about the information-exposure experiment we conducted to test the conjecture that “science curiosity” tends to negate politically biased information processing.

Maybe first though I should say something about why this sort of result isn’t an obvious one.

Or actually why it is is obvious-- but why a result the other way would have been obvious, too!

The best studies, in my view, are ones that test opposing plausible conjectures.  This is the upshot of the “more things are plausible than are true” principle, which I attribute to Duncan Watts (2011).

It’s the premise, basically, of his cool book “Everything is Obvious: Once you know the Answer.”  Because more explanations for interesting social phenomena are plausible than are actually true, if one doesn’t use empirical methods to extricate the true (or more likely true) from the sea of plausible but false explanations, one drowns in a sea of just-so story-telling.

But of course, once one does the work of presenting valid empirical evidence that furnishes more reason to believe one plausible conjecture rather than its rival, someone will inevitably trot out the boring  OCTUSW--"Of course--that's unsurprising--so what"—response. 

To which the answer is, YAIIFTOTBTTWHBEO!, or “Yup; and if I’d found the opposite to be true, that would have been equally ‘obvious’! Aren’t you glad, then, that I actually went to the trouble of trying to generate some actual evidence instead of just lazily taking a bunch of plausible behavioral mechanisms, adding water & stirring—to produce the instant pseudo-science profundity that passes for decision science in op-ed pages & best-selling books?”

Indeed, I make a point of doing only studies about which someone could say, "Of course, that's unsurprising so what" no matter which way the study result comes out

But by the time you say all  this, of course, Mr. or MS OCTUSW has moved on to some other topic about which he or she can make this or some equally penetrating remark.

Anyway!

Why would a result the opposite of what we found—viz., that highly science curious individuals, unlike less curious ones, willingly expose themselves to evidence that confounds their political predispositions—not have been particularly surprising?

The answer is “motivated system 2 reasoning” – or MS2R.

MS2R refers to the tendency of the reasoning proficiencies associated with science comprehension to magnify rather than abate politically motivated reasoning (PMR)—the tendency to conform evidence to one’s political predispositions. 

Cognitive reflection, numeracy, science literacy—they all do that (Kahan in press).

Does that outcome seem obvious, too?

Maybe!

But the opposite effect—the tendency of proficiency in these sorts of reasoning abilities to temper political polarization—certainly is plausible, and any evidence that they do would certainly have been “obvious—once one knew the answer.”

Most cognitive biases—from base rate neglect to the availability heuristic, from ratio bias to the conjunction fallacy—reflect an overreliance on the rapid, intuitive, affect-driven “System 1” information processing as opposed to the more deliberative, conscious, dispassionate “System 2” kind characteristic of good “scientific” reasoning.

PMR compromises truth-convergent Bayesian reasoning in a manner akin to these biases. So why wouldn’t one expect it, too, to be attributable to overreliance on heuristic, system 1 reasoning ?

Plausible!

But false.  Tons of observational & experimental data at this point show that cognitive reflection, numeracy, science literacy, etc.,  are all associated with greater political polarization.

Under the conditions that generate PMR, people use their science-comprehension reasoning proficiencies to reinforce their biased assimilation of evidence to the position that coheres with their political predispositions.

That’s MS2R!

Now science curiosity—just like cognitive reflection, numeracy, knowledge of basic science facts, etc.—is cognitive element of science comprehension.

I went over this in a post a couple of days ago that showed  that people high in science curiosity are significantly more likely to be high in science comprehension than are those who are low in science curiosity.

Can you see now why it would have been perfectly plausible to surmise—and perfectly obvious to find—that science curiosity, like these other elements of science comprehension, magnify political polarization?

But there’s a perfectly respectable conjecture the other way: that unlike these other elements of science comprehension, science curiosity involves an appetite to be surprised—to experience the awe and wonder of contemplating surprising insights derived from the signature methods of science.  Maybe the habitual exercise of that disposition develops habits of mind that counteract rather than accentuate PMR.

Maybe! Or maybe not!

Only one way to tell . . . . Do a valid empirical study.

Oh-- & then do another, & another & another –and progressively update one’s views on the respective probability of these two perfectly plausible hypotheses—viz., science curiosity amplifies & science curiosity mitigates PMR.

So there you go, Mr./MS. OCTUSW.

We are now ready to (re)turn to the more interesting question: what was the evidence we relied on and how much reason does it give us to credit the “science curiosity mitigates” PMR hypotheses.

But I've said enough for one day, so  I’ll have to do that “tomorrow.”

Again, though, if your insides are being consumed by curiosity on the experiment design and results, don't suffer--just download our paper & read it . . . . right now!

Science curiosity & climate change (de)polarization (new paper)

Consider four propositions of ascending curiousness.

  1. Increasing science curiosity is associated with greater acceptance of human-caused climate change in the general population.

  2. This effect holds regardless of political outlooks

  3. Increasing science curiosity counteracts the association between increased science comprehension and and political polarization on societal risks such as climate change and fracking.

  4. As science curiosity goes up, individuals of all political outlooks become more interested in engaging information contrary to their political predispositions on climate change.

Proposition (1) is kind of interesting, but until it is combined with proposition (2), it doesn’t tell one much of anything.  A population-wide association between some disposition and a belief or attitude is interesting only if there isn’t significant variation in that relationship among different sorts of people. If there is, then the population-wide effect obscures that and invites specious inferences about how the disposition in question influences the relevant belief or attitude.

Let’s call the class of specious inferences the “Pat” fallacy: because “Pat," who is “average” along every conceivable dimension, doesn’t exist, it is a meaningless exercise to treat how some disposition in “Pat” affects “Pat’s” beliefs, attitudes, etc., if in fact relevant dimensions of identity affect the relationship of the disposition to beliefs, attitudes, etc., in real-life, truly existing people.

Click me! I'm the best image in this post!But once we know that there is a uniform relationship between some disposition and some belief or attitude (or one that is uniform in relation to some meaningful aspect of individuals' identities), then we can start to assess the significance of that.

The clue to the significance here is revealed by (3).  We know (because it’s been shown 15x10^3 times) that pretty much every conceivable reasoning disposition relevant to science comprehension magnifies rather than ameliorates political polarization on societal risks.  That happens because where positions on a risk or like fact become badges of membership in and loyalty to one or another tribal group, people will face strong psychic pressure to use their reasoning proficiencies to filter information in a manner that promotes their beliefs to the ones that that predominate in their groups.

Science curiosity is a reasoning disposition that can reasonably be understood to be integral to science comprehension. So one might expect it to magnify polarization on issues like climate change, too.

No! Don't listen to her! I'm the best image! Click me!!!!But it doesn’t. It has the opposite effect!

Why? Why?? Why???

This is the question that the 14 billion readers of this blog were left to grapple with about 5 mos ago when propositions 1-3, which were observed in Study No. 1 of the Cultural Cognition Project/Annenberg Public Policy Center “Science of Science Filmmaking Initiative.”

One conjecture was that science-curious individuals might be using their reason in a way that counteracts the usual consequences of politically motivated reasoning (PMR). 

Generally speaking, PMR is associated with biased information search: that is, partisans tend not only to fit their assessments of information to their predispositions, but to focus their attention on information sources that can be expected to confirm rather than challenge the positions that cohere with their political outlooks (Hart, Albarracín, et al. 2009)..

But scientifically curious people have an appetite to be surprised by the insights generated by the use of science’s signature methods of disciplined observation, measurement, and inference.  That appetite might impel them, unconsciously, to expose themselves more readily than their less curious political peers to expose themselves to information that is contrary to their predispositions.  If so, they might end up with perceptions of risk that are at least a bit closer to those of their political opposites who are scientifically curious and who are doing the same thing.

That was the animating hypothesis of an experiment, the outcome of which is the basis of proposition 4.  In that experiment, we—my collaborators at CCP and APPC—tested just how readily partisans would expose themselves to surprising scientific evidence on climate change when that evidence was contrary to their political predispositions (Kahan, Landrum, Carpenter, Helft & Jamieson in press).

Absurd! I'm clearly the coolest image in this post. Click me, or I'll destroy the entire internet!!!We found that individuals who were low to moderate in curiosity wouldn’t do it. They opted for “familiar” evidence supportive of the position associated with their own political outlooks.

But highly curious subjects behaved differently. Confronted with the chance to peruse some surprising evidence that challenged their existing views, they went for it.

I guess they just couldn’t resist!

What exactly did we do to elicit this observation? Well, I’ll tell you about that “tomorrow.”

Or if you are just so curious you can’t wait until then, you can check out our new CCP/APPC Science of Science Communication Initiative paper, “Science Curiosity and Political Information Processing” for details!

"Mirror mirror on the wall ... who is the most partisan of all?!" MAPKIA Episode No. 978!

Hey, everybody, I think you know what it's time for . . . .

That’s right-- another episode of Macau's favorite game show...: "Make a prediction, know it all!," or "MAPKIA!"!

To get the technicalities out of the way, here's the posting of the "official statement of contest terms & conditions,"  as mandated by the Gaming Commission:

I, the host, will identify an empirical question -- or perhaps a set of related questions -- that can be answered with CCP data. Then, you, the players, will make predictions and explain the basis for them. The answer will be posted "tomorrow." The first contestant who makes the right prediction will win a really cool CCP prize (like maybe this or possibly some other equally cool thing), so long as the prediction rests on a cogent theoretical foundation. (Cogency will be judged, of course, by a panel of experts.)

Okay, this is a tricky one!

It’s going to take (a) a Feynmanite/Selbstian level of analytical thought, (b) a Fredrickian resistance to the seductive tug of WEKS, plus (c) a Barry-Bonds-sized dose of political-psychology HGH (& yes former Freud expert & current stats legend Andrew Gelman and Josh " 'Hot Hand Fallay' Fallacy" Miller both remain eligible for this MAPKIA pending their appeals for testing positive in the aftermath of their stunning post “CCP-APPC Political Polarization IQ Test”™ victories).

Let’s start by creating a “political partisanship index.”  The recipe for that is as follows:

  1. Take a left-right political outlook scale formed by standardizing the sum of the sums of responses to conventional 7-point political-party identification and 5-point liberal-conservative ideology survey items. A very nice feature of this approach when one uses it with a nationally representative sample is that “0” is “moderate Independent,” while -1 and +1 SD are “liberal Democrat” and “conservative Republican,” respectively. Scores in the vicinity of -1.8 and +1.8 will be “Extremely liberal, Strong Democrat” and “Extremely conservative, Strong Republican,” respectively. In case you’ve forgotten how nicely this simple scale performs in picking in partisan polarization on contested issues, check out the policy-polarization figure below or watch a re-run of the wildly popular episode on the “CCP-APPC PPQ IQ Test”™).

  2. Then take the absolute value of the scores on this Left_right scale. The result is a “Partisanship Index” (PI), one that registers the intensity of one’s left-right outlooks without regard to their valence. Thus, if one is either a “liberal Democrat” or a “conservative Republican,” one gets a PI score of “1.0.” If one is either an “Extremely liberal, Strong Democrat” and “Exremely conservative, Strong Republican,” one gets a PI score of 1.8. A milqetoast politically sissy who is a “moderate Independent” will get a score of “0.”

Okay, got that?  Good. (If you are curious for what the relationshop between Left_right and PI looks like without smoothing--and why the intercept for zero on y axis is slightly above zero--good for you! Click here).

Now here is the MAPKIA question:

What is the profile of a “super partisan”? On the basis of characteristics like (a) gender, (b) race, (c) income, (d) education, (e) science comprehension (measured by OSI), (f) science curiosity (measured with SCS), (g) religiosity, (h) cultural worldivews (measured with the CCW scales) etc. or appropriate combinations thereof, who is the most partisan “type” of person (i.e., gets the highest PI score) in U.S. society????

You know the rules: don’t just gesture toward an answer in some vague discursive way; be specific, both about what your conjecture and why, and tell me how to test it using the sort of data that typically appears in a CCP data set.

Realize that basically the question is, What's the relationship between the specified characteristics and partisanship? If you want to specificy simple correlations between partisanship and one or more of these attributes or (better still)  combinations of them, that's fine!

But if you have some more clever way to specify how the characteristics should be combined into some latent-variable "identity" variable or how the relationship between the characteristics (individually or in combination) should be related to the Partisanship index (in that regard, you might want to check out "yesterday's" post on how science curiosity and science comprehension relate to each other), go for it!

Now, an important proviso: Do not tell me to just jam every one of these characteristics onto the right hand side of a goddam linear regression and “see what comes out statistically significant.”  The reason  is that the results of such an analysis will be gibberish. 

Actually, the R2  will be fine & might be interesting if you want to get an idea of the the upper limit of the possibilities for explaining PI. But the parameter estimates will be meaningless in relation to our task, which is to identify the sorts of real-world people who are super partisans. 

And with that . . . mark, get set, MAPKIA!

What is the relationship between science curiosity & science comprehension? A fragment . . .

From something I’m woring on (and useful refinement of this discussion of how to think about size of individual differences in one or another reasoning disposition). . .

c. Compared to ordinary science intelligence. Science curiosity—generally or as measured here—ought to be have some relationship to science comprehension. It is difficult to experience the pleasure of contemplating scientific insight if one is utterly devoid of any capacity for making sense of scientific evidence. Similarly, if one is aggressively uncurious about scientific insights, one is less likely to acquire the knowledge or the experience-based habits of mind to reason well about scientific insights.

Yet the two dispositons shouldn’t be viewed as one and the same.  Many people who can detect covariances and successfully compute conditional probailities—analytical tasks essential to making sense of empirical evidence—are nevertheless uninterested in science for its own sake.  Even more obvious, many people who are only modestly proficient in these technical aspects of assessing empirical evidence are interested—passionate even—about science. In sum, one would expect a science-curiosity measure, if valid, to be modestly correlated with but definitey not equivalent to a valid science comprhension measure.

SCS, the science-curious measure we formed (Kahan, Landrum & Carpenter 2015), has these properties.  The association between SCS and the Ordinary Science Intelligence (OSI) assessment (Kahan 2016) was r = 0.26 in our two data collections. To make this effect more practically meaningful,

SCS has these properties.  The association between SCS and the Ordinary Science Intelligence (OSI) assessment (Kahan 2016) was r = 0.26 in our two data collections. To make this effect more practically meaningful, the relationship between these measures implies that that individuals in the top quartile of SCS are over four times more likely than those in the bottom quartile to score in 90th percentile or above on the OSI assessment (Figure 6).  This is a degree of association consistent with the expectation that higher science curiosity contributes materially to higher science comprehension. Nevertheless, in both studies science comprehension lacked meaningful predictive power in relation to engagement with the three science videos featured in our two studies (Figure 7). In other words, SCS measures a disposition that is apparently integral to the kind of proficiency in scientific reasoning measured by OSI, yet generates a form of behavior—the self-motivated consumption of science information for its own sake—that is unassociated with science comprehension by itself.

What antagonistic memes look like: the case of the HPV Vaccine

From the new APPC/CCP Working Paper, Culturally Antagonistic Memes & the Zika Virus

2.1. In general

* * *

“Memes” refer to ideas and practices that enjoy wide circulation and arouse self-reinforcing forms of attention as well as spontaneous adaptation and elaboration (Balkin 1998; Blackmore 1999). A small subset of these sorts self-replicating ideas and practices, the ones we call “culturally antagonistic memes” refer to highly evocative, highly inflammatory argumentative tropes used by members of one group to stigmatize another.

When they figure in debates over risk, these contempt-pervaded tropes invest positions on them with affective resonances symbolic of opposing groups’ values or identities.  In the resulting discourse climate, individuals will come to perceive risk regulation as “express[ing] the public worth of one subculture’s norms relative to those of others, demonstrating which cultures have legitimacy and public domination” and thereby “enhnanc[ing] the social status of groups carrying the affirmed culture and degrad[ing] groups carrying that which is condemned as deviant” (Gusfield 1968, p. 59). Conducted in the idiom of instrumental consequences, the stances diverse citizens adopt on which activities genuinely threaten society and which policies truly mitigate the attendant dangers are become rhetorical subterfuges in an “ongoing debate about the ideal society” (Douglas &Wildavsky 1982, p. 36). 

This process is effected through a decisive switch in the sort of information processing that is characteristic of the AH-CCT model. From a reliable and consensus-generating guide to valid decision relevant-science, the affective heuristic and cultural cognition at this point combine to generate a divisive, nontruth-convergent source of identity-protective cognition (Sherman & Cohen 2002; Kahan 2010).

By fusing contending positions on a risk or like facts to opposing group identities, antagonistic memes effectively transform positions on them into badges of membership in, and loyalty to, competing groups. Because this state of affairs pits opposing groups’ knowledge-certification systems against one another, the forms of information-processing associated with cultural cognition and the affect heuristic will under these conditions necessarily lose their power to generate truth-convergent forms of consensus across them.

This switch will not cause such information processing to abate, however.  There is rarely any personal action that an individual can take that will affect the level of danger that a societal risk poses to him or anyone he cares about; his decisions as a consumer, voter, or participant in public debate won’t matter enough, for example, to affect the course of climate change, or the regulation of fracking, or the siting of nuclear waste facility.  In contrast, such an individual’s personal behavior, including the attitudes he evinces on issues infused with social meanings, will typically have tremendous significance for the impressions that others form of his character (Sherman & Cohen 2002; Lessig 1996).  As a result, it will be individually rational, if collectively disastrous, for individuals to form habits of mind that reliably produce identity-affirming rather than accurate ones when societal risks become infused with meanings that divide their groups from others (Kahan 2015b).  

Hi, it's me again! Click me to say hello!Indeed, these habits of mind will become seamlessly interwoven into the capacities essential for assessing scientific information. “Motivated system 2 reasoning” refers to the tendency of individuals to use their proficiency in Numeracy, cognitive reflection, and science comprehension to ferret out and credit identity-congruent evidence and explain away the rest (Kahan in press_b).  Much as a virus does to the genetic material of an otherwise healthy cell, identity protective cognition effectively insinuates itself into reasoning dispositions essential to recognizing the best available evidence (Kahan 2013; Kahan, Peters et al.  2013).  Their cognitive faculties having been redirected in this fashion, the individuals most adept in these forms of reasoning will end up the most polarized on culturally contentions risks (Hamilton 2011, 2012; Kahan, Peters et al..  2012).

Identity-protective cognition is thus not a not a natural outgrowth of but rather a pathological deformation of the processes associated with the AH-CT model. The trigger of this pathology, moreover, is the advent of culturally antagonistic memes (Figure 1).

2.2. A concrete illustration

Many persistently contested science issues fit this pattern.  But we will focus on one that we believe is particularly well suited for illustration: the U.S. experience with the HPV vaccine.

I dare you: click me!

The HPV vaccine confers (near-perfect) immunity to the human papilloma virus, an extremely common s

exually transmitted disease that cause cervical cancer.  The vaccine also has the distinction of being the only childhood immunization recommended for universal administration by the U.S. Centers for Disease Control that is not now on the schedule of mandatory school-enrollment immunizations in the United States.  Legislative proposals to add it were defeated in dozens of states in the years from 2007 to 2008 as a result of intense political controversy over the safety and effectiveness of the vaccine (Kahan 2013).

Although the proposal to add the HPV vaccine to the list of mandatory vaccinations divided the public along predictable lines, the conflict over it was in fact not inevitable.  Only a few years before nearly every state had endorsed the CDC’s proposal for universal administration of the HBV vaccine, which likewise confers immunity for a sexually transmitted disease, hepatitis-b, that causes cancer (of the liver).  The HBV vaccine is now given in infancy, but at that time it was an adolescent shot, just like the HPV vaccine.  During the years in which legislative battles were raging over the latter vaccine, nationwide vaccination rates for the former were well over 90% (ibid).

Like every other childhood vaccine that preceded it, the HBV vaccine was considered and approved for inclusion in state universal-immunization schedules by non-political public health agencies delegated this expert task by state legislatures.  The vast majority of parents thus learned of the vaccine for the first

time when consent to administer it was sought from their pediatricians, trusted experts who advised them the vaccine was a safe addition to the array of prophylactic treatments for keeping their children healthy.  Just as important, regardless of who these parents were—Republican or Democrat, devout evangelical or atheist—they were all afforded ample evidence that parents just like them were getting their kids vaccinated for HBV.  This is a science communication environment in which the AH-CCT model can be expected to generate largely convergent affective reactions across all groups—exactly the outcome that was observed.

The HPV’s vaccine path to public awareness, in contrast, was much more treacherous. Seeking to establish a dominant position in the market before the approval of a competing shot, the manufacturer of the HPV vaccine  orchestrated a nationwide campaign to establish immunization mandates by statutes enacted by state legislatures.  What was normally a routine, nonpolitical decision—the administrative updating of states’ mandatory-vaccination immunization schedules—thus became a high-profile, highly partisan dispute.  People became acquainted with the vaccine not during visits to their pediatricians’ office but while viewing Fox News, MSNBC, and other political news outlets. There they were bombarded with reports on the “slut shot” (Taormino 2006) and “virgin vaccine” (Page 2006) for school girls, a framing enabled by the manufacturer’s decision to seek fast-track FDA approval of a women’s-only shot as part of company’s plan to vault over the conventional, less speedy, depoliticized administrative-approval process (Gollust, Lorusso et al.  2015).

These media stories and resulting social media reaction were replete with what we are referring to as “culturally antagonistic memes.”  “Trust us: Vioxx, Now Gardasil,” declared a viral internet feature that mocked the manufacturer’s own advertising campaign (Figure 2). “HPV vaccine: Republicans prove themselves morons once again,” sneered liberal commentators (2011). “They value your virginity more than your life,” another righteously intoned; “there was a time when only the loony left believed that the loony right favored death over sex; not any more” (Goodman 2005).  Individualist-oriented commentators retorted: “Let’s use teenage girls as lab rats for a monopoly” (Erickson 2011).

These are exactly the conditions one would expect to fuse a risk issue to antagonistic social meanings, thereby triggering identity-protective cognition on the vaccine’s risks and benefits (Fowler & Gollust 2015; Bolsen, Druckman & Cook 2013).  Studies confirmed that exactly that happened (Gollust, Dempsey et al.  2010; Kahan et al.  2010).

What antagonistic memes look like: the case of the Zika virus

From the new APPC/CCP Working Paper, Culturally Antagonistic Memes & the Zika Virus:

3.1. Why Zika

The focus of the study was the impact of culturally antagonistic-meme generating communications on the perceived risks of the Zika virus.

We selected the Zika virus for two reasons. The first is that we are confident there isn’t currently meaningful cultural dissensus on Zika at the current time. For over five months, the Annenberg Public Policy Center (2016a) has been tracking U.S. public opinion on the disease. Attention early on spiked and then leveled off, and is now rising again; knowledge about the health effects of the virus and about effective means of self-protection have proven uneven; certain misunderstandings about the link between the virus and microcephaly have persisted, albeit at modest levels (Annenberg Public Policy Center 2016b).

But nothing in this mix varies meaningfully with ideology, religion, or like forms of cultural identity.  There is reason to be apprehensive about the speed with which members of the public are progressing in their understanding of key facts about the virus. But the evidence suggests that culturally diverse members of the public are progressing in unison, much in the manner one would expect under the “normal,” nonpathological process contemplated by the AH-CCT Model (Figure 1).

click me-- more refreshing than a cold lemonaid in the middle of an AGW heatwave!At the same time, there has been a steady accumulation of communications tying the Zika health threat to already culturally charged issues (Figure 3).  The voice of public health officials furnishing the public with precautionary advice is only one in a chorus, whose other members include a collection of advocacy groups all seeking to leverage public anxiety over Zika into greater attention to their special cause.

Among these are anti-immigrant groups. These actors suggest that the spread of Zika is likely to be accelerated by undocumented aliens as well as lawful immigrants from Zika-affected regions. “Latin America’s Zika virus is the latest undocumented immigrant to hit our shores,” one commentator caustically notes (Malkin 2016). It’s obvious from the “available evidence” that “open borders contribute to the vulnerability of the United States to the virus” (Corsi 2016). “People from Central and South America, ground zero for Zika and other infectious diseases including tuberculosis, dengue, Chagas, Chikungunya and schistosomiasis, make up nearly 15 percent of the illegal-immigrant population in the U.S.” (Malkin 2016). “[A] drain on our economy, a peril to our national security, and a drag on our souls,” illegal immigrants are now “hazardous to our health, thanks to sloppy U.S. immigration laws acting as incubators for diseases once foreign to North America — like the untreatable Zika virus” (Abruzzo 2016).

Climate change advocates have also latched onto Zika. “Zika is the kind of thing we’ve been ranting about for 20 years,” one observes. “We should’ve anticipated it. Whenever the planet has faced a major climate change event, man-made or not, species have moved around and their pathogens have come into contact with species with no resistance” (Milman 2016). Now “thanks to climate change” Zika could “soon enjoy a greater reach” (Mercer 2016), “spread[ing] deeper” into now secure areas of the U.S. (Gillis 2016).  Of all the “tragedies stemming from global warming,” including the “floods and droughts and storms, the failed harvests and forced migrations, . . . no single item on the list seems any more horrible than the emerging news from South America about the newly prominent Zika disease” (McKibben 2016). “We need to face up to the fact that pushing the limits of the planet’s ecology has become dangerous in novel ways.”  “The Republicans are in denial about climate change, but in the real world, we can feel it . . . . It’s also an invitation for breeding mosquitoes and putting Americans at risk all across the United States” (Johnson 2016).

The situation presented, then, furnishes an ideal one to extend previous research.  The tropes that inform advocacy material linking Zika to other culturally contested issues are replete with the accusatory and resentment-focusing tropes featured in highly polarized risk disputes. Yet in no  previous study  has there been an opportunity to test the impact of such tropes in relation to an issue not already the subject of at least modest contestation.

It is possible, of course, that the explanation for the patchwork of contestation and tranquility that forms the fabric of public risk perception is some as-yet undetected factor intrinsic to particular risk sources. It is perfectly plausible to believe, too, that deeper, historical influences render a particular risk source either impervious or distinctly amenable to controversy of a particular form, in particular societies. But through an appropriately constructed study, one can test the alternative hypothesis that it is the contingent advent of exposure to culturally antagonistic memes that triggers such conflict, and accounts for its complexion and intensity.  The study we conducted was aimed at furnishing evidence relevant to assessing the relative plausibility of these alternative conjectures.

New paper: Zika risk perceptions & culturally antagonistic memes!

Latest from the APPC/CCP "Science of scienc communication initiative working paper series" (previous installments include Kahan, D.M. ‘Ordinary science intelligence’: a science-comprehension measure for study of risk and science communication, with notes on evolution and climate change, J. Risk Res, 1-22 (2016), & Kahan, D.M. Climate-Science Communication and the Measurement Problem, Advances in Political Psychology 36, 1-43 (2015)). More on this paper "tomorrow."

 

Culturally Antagonistic Memes and the Zika Virus: An
Experimental Test

Abstract

This paper examines a remedy for a defect in existing accounts of public risk perceptions. The accounts in question feature two dynamics: the affect heuristic, which emphasizes the impact of visceral feelings on information processing; and the cultural cognition thesis, which describes the tendency of individuals to form beliefs that reflect and reinforce their group commitments. The defect is the failure of these two dynamics, when combined, to explain the peculiar selectivity of public risk controversies: despite their intensity and disruptiveness, such controversies occur less frequently than the affect heuristic and the cultural cognition thesis seem to predict. To account for this aspect of public risk perceptions, the paper describes a model that adds the phenomenon of culturally antagonistic memes—argumentative tropes that fuse positions on risk with contested visions of the best life. Arising adventitiously, antagonistic memes transform affect and cultural cognition from consensus-generating, truth-convergent influences on information processing into conflictual, identity-protective ones. The paper supports this model with experimental results involving perceptions of the risk of the Zika virus: a general sample of U.S. subjects, whose members were not polarized when exposed to neutral information, formed culturally polarized affective reactions when exposed to information that was pervaded with antagonistic memes linking Zika to global warming; when exposed to comparable information linking Zika to unlawful immigration, the opposed affective stances of the subjects flipped in direction. Normative and prescriptive implications of these results are discussed.

Weekend update: Could Trump really win? What people do & don't *fear* says, "sure, why not?"

Thursday
Jul072016

Why don't we have more gun control given that there is such overwhelming bipartisan public consensus in favor of that policy? WEKS strikes again . . .

So there have been a rash of news commentaries recently about “why” we don’t have more gun control given that there is overwhelming  “public support” for it.

I myself have offered explanations for this in the past.

But I’m wondering: is the premise really true? Is there really overwhelming public support for more gun control?

Or is this (like the “astonishing change in societal norms on gay marriage”) another instance of “WEKS” – “ ‘what everyone knows [is true]' syndrome,” the condition in which people with like-minded cultural outlooks convince themselves that “everyone” agrees with them on some issue that is in fact highly contested as a cultural matter?

Well, here’s some evidence for WEKS:

click for bigger viewAs the captions indicate, the data come from two separate APPC /CCP studies, one just concluded and the other from Jan.

They both show that gun control is not only massively polarizing but is among the most polarizing issue in American politial life—right up there with climate change and affirmative action.

The left-hand panel uses the tried-and-true Industrial Strength Risk Perception Meaure, which, as a result of the “affect heuristic” (Finucane, Alhakami, Slovic & Johnson 2000), magically encapuslates in one simple it the same level of covariance one would see when one relates the variable on the x-axis (here political outlooks) to any other more specific question that individuals would recognize as having to do with the risk in questin (e.g., on global warming, “is it happening,” “are humans causing it,” “are we all going to suffer horrendous harm as a result of it” etc).

It helps to show, then, that the proposition that there is as much polarization on guns—whether one frames the issue as one of the risks of allowing or not allowing people to have them—as there is on climate change, which is pretty much the most polarizing issue today (maybe ever) in American politics (there’s definitely a lot of “WEKS” on that, btw, although there is also the disturbing influence of attempts to “message” people with invalid surveys; maybe I’ll talk about that “tomorrow”).

click here for policy preference item wordingI put the right-hand panel in to help show that the sort of polarized affective responses look like when one cashes them out in terms of “policy positions.”

It shows, again, that proposals for stricter gun control laws have the same political-polarization profile as many of the issues we recognize as benchmarks of left-right factionalization.  I’ve also put in a couple of “non-polarized” issues just as a reference point (if you didn’t know vaccines were non-polarizing, you need to get out—of the WEKS bubble—more often).

Those data, again, are from Jan.

But another reason for putting in the left-hand side ISRPM panel is to help asnwer the question whether “something might have changed” given recent mass shooting.  Because the covariance from the ISRPM will always be nearly identical to the covariance on policy issues like this (for a miraclous proof of that propostion, check this out), we can be confident that if we are seeing the sort of ISRPM profile displayed in the left-hand panel, then we’d still see today the sort of division on “policy preferences,” or any other gun control question we might ask that people could actually understand.

So . . .

Why do so many people (but not all! there are plenty of people, it should be pointed out, who recognize gun control is polarizing) think there is consensus in the public for more gun control?

Like I said, I’ve definitely myself formed and expressed this impression myself!

But I do think it is almost certainly WEKS at work.  The people who say there is consensus for "more control" are on the “left” or at least tend to be inside the left’s political-communication bubble. Actually, people on the "right" think there is consensus against gun control; they live in their own bubble!

But there might be other explanations, too. . .

What do you think?

Travel report: Has liberal democracy lost its power to motivate?

This is a belated postcard from stop on recent around the world (I know it was because it included both Cambridges—UK and US—with lots of stops in between) tour. . . . It reports on one of two talks I gave at the annual Breakthrough Institute Dialogue series.  This one was part of a panel on “Progress Problems,” in which the question that I and the other panelists, who included Max Roser and Lydia Powell, addressed was “why are so many of the richest and most privileged people on earth, despite reaping such extraordinary benefits,  convinced that progress is a mirage and modernity must inevitably end badly?My remarks, as best as I can recall them, were as follows (slides here) . . . .

So the question as I understand it is --

Have liberal democratic ideals lost the power to motivate the citizens of liberal democracies?

Can we summon their attention to the common challenges they face by invoking their shared commitment to self-government, civil liberties, and free markets? Or are the animating ideals of liberal democracy now themselves a source of estrangement and division that ennervate public spiritedness?

My answer to these qustions will take a dialectical form. That is, like Clint Eastwood at the Republican Convention of 2012, I will treat you to a disagreeable dialogue with myself, in which I will radically change direction at least twice.

But insofar as I will get the last word, I’m confident that I’ll ultimately come out on top in the exchange.

So to start, with . . .

                Thesis: Sure, those ideals can motivate! I’ll show you . . . .”

I’ll show you, that is, an experiment (Kahan, Jenkins-Smith et al. 2015), one in which invoking the spirit of liberal democratic institutions sharpened apprehension of, and magnified the will to address, a collective challenge –namely the one posed by human-caused global warming.

In the experiment, we measured the willingness of subjects (members of two separate nationally representatives samples, one from  American and the other from England) to engage open mindedly with a climate-change study.

A composite of two real studies (Allen et al. 2009; Solomon et al. 2009), the one featured in our experiment—call it the “Nature-Science study”—told a bleak story. Scientists, it reported, had overestimated the speed with which carbon dioxide dissipates. As a result, even if human beings were to cease generating all greenhouse gasses tomorrow, past emissions would guarantee continued increases in global temperatures along with devastating consequences—from catastrophic flooding of coastal regions, to production-ending droughts in agricultural ones—for decades to come.

We also measured our subjects cultural worldviews along the two dimensions—hierarchy-egalitarianism and individualism-communitarianism—featured in studies of the cultural cognition of risk (Kahan 2012).

As we anticipated, experiment subjects of a hierarchical, individualistic orientation—the ones most predisposed to climate skepticism—were preemptively dismissive of the Nature-Science study results.

This, however, was in a control condition, in which subjects, before grappling with the Nature-Science study, read a news article about a town meeting over a proposal to install traffic lights in the vicinity of a new residential development.

Subjects in two other conditions were assigned to read different news articles: in one, a story about how a national association of preeminent scientists had issued a statement calling for increased limits on human CO2 emissions to combat global warming; and in the other, a story about how the same association had issued a statement calling for research on geoengineering to offset the effects of past and future emissions. We labeled these the “anti-pollution” and “geoengineering” conditions.

Logically, there’s no reason why subjects assigned to either of these conditions should have formed different views on the validity of the Nature-Science study: the validity of the evidence for an asserted problem doesn’t turn on whether someone approves or disapproves of any particular solution for it.

But psychologically, the solution might well matter.

The “anti-pollution” and “geoengineering” stories embed the problem of climate change in different narratives and thus invest it with alternative social meanings (Lessig 1995).

The former narrative is about the inevitable limits on technological ingenuity and the consequences for having too long ignored them. Against the background of the “anti-pollution story,” the message of the Nature-Science story is  “game over” and “I told you so.”

Individuals of a hierarchical, individualistic cultural outlook revere commerce and industry, not just for what they do but for what they signify about human resourcefulness and the welfare-enhancing consequences of spontaneous private orderings and the stratified systems of authority that they spawn.  They are motivated, unconsciously, to resist evidence of the existence and impact of human-caused climate change precisely because they know that if society credits such evidence it will call into question the premises of their preferred way of life.

The social meanings in the anti-pollution story reinforce that perception, and hence amplify the motivation to resist the evidence.

But the message of the “geoengineering story” is very different.

We are not the stupid animal, this narrative goes, who when it reaches the top of the Malthusian curve comes crashing down ass over tincups.  We shift the f***ing curve!

Drinking your own shit, you say? No problem! Try modern sanitation & you can increase the density of cities 10 fold relative to what a bunch of tight-sphinctered naysayers once told us was the “natural limit,” enforced by the dreaded penalty of cholera outbreaks.

Well, it’s time to shift the curve again! This time with mirror-coated nanotechnology flying saucers that magically—hell, not magically; by rational intention & design—spontaneously assemble at just the right attitude to cool the atmosphere to a predetermined, geo-thermostatically determined level.

Not “game over” but more of the same!

“I told you so”? Unh uh! Try, yes we can!

Whereas the social meanings implicit in the “anti-pollution” story narrative threaten and denigrate the identity of the hierarch individualist, the meanings implicit in “geoengineering” affirm and gratify his vision of the best life and its prospects

The result is an abatement of the unconscious, reflexive resistance to evidence that there is in fact a problem to be addressed—by one means or another.

In any case, that was the conjecture we wanted to test in our experiment.

And it was the result that we in fact observed.

Relative to the control condition, hierarchical individualists in assigned to read the “anti-pollution” news story first became even more skeptical, even more dismissive of the validity of the Nature-Science study, increasing polarization within the study sample.

But those who read the “geoengineering” story first were decidedly more receptive to the evidence in the Nature-Science study; they didn’t dismiss its findings out of hand. 

As a result, polarization, over the validity of the study and over the reality of human-caused climate change, both decreased.

So there you go!

The ideals of liberal democracy include the  confidence that people have that technology, human ingenuity, private orderings, and individual strivings can in the course of freeing us from the limits of nature, devise effective solutions for problems of their own making.

Invoking these ideas, narratively, can inspire, can summon attention to common problems and the will to address them!

I’ve shown you!

 Antithesis: “No they can't! Take a closer look.”

Hold on.

Sorry.

What you’ve shown us is that liberal democratic ideals can’t genuinely motivate the citizens of liberal democratic regimes.  Just take a closer look at your own data, and you’ll see.

Yes, relative to their counterparts in the “antipollution” condition subjects in the “geoengineering” one became more open-minded about climate change.

But egalitarian communitarian subjects—people of the sort who normally are “climate concerned”—became less so.

They are the citizens who bridle at the self-centered acquisitiveness implicit in market institutions and in liberal conceptions of individual rights.

For them, the meanings of boundless individual ingenuity and permanent technological progress that pervade the narrative implicit in the “geoengineering” condition threatened and denigrate their identity.

If the meaning of climate change is “yes, we can” and “more of the same!,” then they want none of it.

Or least they want less.  Things aren’t that bad, egalitarian communitarian subjects assigned to the “geoengineering” condition said after reading the Nature-Science study.  We can still make “progress” by shutting down industry, turning off modern agricultural techniques, and simply retreating into a pre-modern style of economic life.

The scientists who wrote this study are biased, are relying on unproven computer models, are furnishing us with evidence that it would be precipitous to use in policymaking without a lot more corroboration etc etc.

Sound familiar? These are the tropes of skepticism—now from the mouths of those most inclined to be embrace climate change.

Why? Because what they really care about, what motivates them, is not  “evidence” (they definitely lack the science literacy to understand it) but the social meaning of “I told you!” and “game over!” (“This changes everything” blah blah) that informs the default narrative on climate change.

Change the narrative and they change their tune.

Just look at your data: They show that, relative to their counterparts in the anti-pollution condition, egalitarian communitarians became skeptical about climate change science in the in the geoengineering condition.

That, plus the greater receptivity to the Nature-Science study data on the part of hierarch individualists, was why there was less polarization in the “geoengineering” condition!

The motivation that invoking liberal democratic ideals, in the form of narratives of limitless technological progress and the self-corrective, self-redemptive power of private orderings and markets, is offset by the resistance that doing so motivates in that portion of or factionalized body politic that has come to despise individual striving, technology, and markets.

You can’t inspire with these ideals!

Invoking them on behalf of one cause of another is a zero sum game. 

Synthesis: “Liberal democratic ideals can indeed inspire--if you just stop obsessively looking at them.

I’m sorry.

You—both of you—are just playing a game.

What is this angst over the loss of the inspirational force of liberal democratic ideals, private markets included?  I mean really, what are you talking about?

Or better why are you focusing so much on talk—by such a small, small group of people who bother to theorize about these things?

Just look a tthe behavior of people—hierarch individualists, egalitarian communitarians, demoKrats/RepubliKans, “liberals,” “conservatives” or whatever.

Ambivalence about technology? Disaffection with consumption?

Ask Apple or Netflix or Amazon if that’s what their bottom lines tell them.

Yes your buddy’s new “environmental studies major” girlfriend is telling you about how environmentally destructive new information technologies are. But she’s showing you on her IPad, which has a “Green Party for Bernie Sander’s” IPad “skin”!

Against capitalism, Naomi Klein? Seriously? (Any chance you’ll show us your tax returns?)

Look.  This s a fashion statement:

And so is this:

Just as these opinions are:

 

Now here’s a worldview:

It’s real.

It’s anti-liberal.

It’s anti-market.

It’s anti-democratic.

And it’s just not on the table, in this society

No one around here finds this genuine repudiation of liberal democratic ideals the least bit inspiring.

The only thing that’s on the table here are the tokens of a demeaning, petty symbolic status competition driven by intellectually juvenile, self-promoting conflict entrepreneurs. . . . 

(Actually, you two guys both have garishly expensive but ridiculously dated sensibilities about fashion; in-your-face black is so 1999! You ain't no Johnny Cash, that's for sure.)

So don’t play that stupid game.

Stop looking & looking & looking at it.

“Messaging”/arguing liberal democracy doesn’t motivate people.

Living it does.
