The seductive allure of neuroscience explanations

Researchers found that sprinkling irrelevant neuroscience into explanations of psychological phenomena significantly increased people’s ratings of them, even when the explanations were wrong.

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.
