Two studies investigated the relative social acceptability of certain prejudices within a society (Study 1) and between societies (Study 2), using (less) internal motivation to control prejudice as an indicator of social acceptability. In Study 1, White British participants reported less internal motivation to control prejudice against people with schizophrenia than against Black people. In Study 2, Jamaican participants reported less internal motivation to control anti-homosexual prejudice than did either British participants or American participants. Other differences in motivation to control prejudice were smaller, absent, or at odds with this difference, indicating that differences in motivation to control anti-homosexual prejudice were not solely due to cultural differences concerning motivation to control prejudice in general. Results are discussed in terms of novel findings, relevance to the literature and possible future research. Copyright © 2011 John Wiley & Sons, Ltd.
