Some recent nonsense (especially the publication of The Male Brain, the newest installment of what one expects again to be the usual dose of bad science by Louann Brizendine), and the generally dismissive attitude towards alleged ‘non-scientific’ knowledge that swamps so much impoverished contemporary intellectual discourse, have reminded me of “The seductive allure of neuroscience explanation“, a 2008 article in the Journal of Cognitive Neuroscience. Here is the abstract:
Explanations of psychological phenomena seem to generate more public interest when they contain neuroscientific information. Even irrelevant neuroscience information in an explanation of a psychological phenomenon may interfere with people’s abilities to critically consider the underlying logic of this explanation. We tested this hypothesis by giving naïve adults, students in a neuroscience course, and neuroscience experts brief descriptions of psychological phenomena followed by one of four types of explanation, according to a 2 (good explanation vs. bad explanation) x 2 (without neuroscience vs. with neuroscience) design. Crucially, the neuroscience information was irrelevant to the logic of the explanation, as confirmed by the expert subjects. Subjects in all three groups judged good explanations as more satisfying than bad ones. But subjects in the two non-expert groups additionally judged that explanations with logically irrelevant neuroscience information were more satisfying than explanations without. The neuroscience information had a particularly striking effect on non-experts’ judgments of bad explanations, masking otherwise salient problems in these explanations.
