The Role of Neuroscience Information in Choosing a Personality Test: Not as seductive as expected

There is a large number of different personality tests used by practitioners for selection purposes, many of which are promoted by commercial test publishers and do not measure the Big Five. The present study examined one particular promotion factor used by at least one successful personality test: the influence of a link between the brain and personality on the decision for or against a personality test. This factor was chosen as past research has demonstrated the seductive appeal of neuroscience information on judgments in other areas. Three samples consisting of human resource practitioners, business management students, and psychology students rated two versions of a fictitious personality test, one with neuroscience information and one without. Contrary to our expectations, the personality test with neuroscience information was rated more negatively than the same test without this information. Human resource practitioners in particular reacted negatively, whereas psychology students were not influenced by our manipulation.
