A comment on Lee Jussim's Social Perception and Social Reality: Why Accuracy Dominates Bias and Self-Fulfilling Prophecy (Oxford 2012).
This comment uses the dynamic of identity-protective cognition to pose a friendly challenge to Jussim (2012). The friendly part consists of an examination of how this form of information processing, like many of the ones Jussim describes, has been mischaracterized in the decision science literature as a “cognitive bias”: in fact, identity-protective cognition is a mode of engaging information rationally suited to the ends of the agents who display it. The challenging part is the manifest inaccuracy of the perceptions that identity-protective cognition generates. At least some of the missteps induced by the “bounded rationality” paradigm in decision science reflect its mistaken assumption that the only thing people use their reasoning for is to form accurate beliefs. Jussim’s critique of the bounded-rationality paradigm, the comment suggests, appears to rest on the same mistaken equation of rational information processing with perceptual accuracy.
