Previous work showed that people find explanations more satisfying when they contain irrelevant neuroscience information. The current studies investigate why this effect happens. In Study 1 ( N=322), subjects judged psychology explanations that did or did not contain irrelevant neuroscience information. Longer explanations were judged more satisfying, as were explanations containing neuroscience information, but these two factors made independent contributions. In Study 2 ( N=255), subjects directly compared good and bad explanations. Subjects were generally successful at selecting the good explanation except when the bad explanation contained neuroscience and the good one did not. Study 3 ( N=159) tested whether neuroscience jargon was necessary for the effect, or whether it would obtain with any reference to the brain. Responses to these two conditions did not differ. These results confirm that neuroscience information exerts a seductive effect on people’s judgments, which may explain the appeal of neuroscience information within the public sphere.

Previous work has found that people are drawn to explanations of psychological phenomena when these explanations contain neuroscience information, even when that information is irrelevant. This preference may be due to a general preference for reductive explanations; however, prior work has not investigated whether people indeed prefer such explanations or whether this preference varies by scientific discipline. The current study asked 82 participants to choose which methods would be most appropriate for investigating topics in six scientific fields. Participants generally preferred methods that either matched the field of investigation (e.g., biology for biology) or that came from the immediately more reductive field (e.g., chemistry for biology). Both of these patterns were especially evident for the pairing of psychology and neuroscience. Additionally, participants selected significantly more methods as being useful for explaining neuroscience phenomena. These results suggest that people’s sense of the relations among scientific fields are fairly well calibrated but display some general attraction to neuroscience.
