The “memory wars” of the 1990s refers to the controversy between some clinicians and memory scientists about the reliability of repressed memories. To investigate whether such disagreement persists, we compared various groups’ beliefs about memory and compared their current beliefs with beliefs expressed in past studies. In Study 1, we found high rates of belief in repressed memory among undergraduates. We also found that greater critical-thinking ability was associated with more skepticism about repressed memories. In Study 2, we found less belief in repressed memory among mainstream clinicians today compared with the 1990s. Groups that contained research-oriented psychologists and memory experts expressed more skepticism about the validity of repressed memories relative to other groups. Thus, a substantial gap between the memory beliefs of clinical-psychology researchers and those of practitioners persists today. These results hold implications for the potential resolution of the science-practice gap and for the dissemination of memory research in the training of mental-health professionals.

Recent research and theorizing suggest that narcissism may predict both positive and negative leadership behaviors. We tested this hypothesis with data on the 42 U.S. presidents up to and including George W. Bush, using (a) expert-derived narcissism estimates, (b) independent historical surveys of presidential performance, and (c) largely or entirely objective indicators of presidential performance. Grandiose, but not vulnerable, narcissism was associated with superior overall greatness in an aggregate poll; it was also positively associated with public persuasiveness, crisis management, agenda setting, and allied behaviors, and with several objective indicators of performance, such as winning the popular vote and initiating legislation. Nevertheless, grandiose narcissism was also associated with several negative outcomes, including congressional impeachment resolutions and unethical behaviors. We found that presidents exhibit elevated levels of grandiose narcissism compared with the general population, and that presidents’ grandiose narcissism has been rising over time. Our findings suggest that grandiose narcissism may be a double-edged sword in the leadership domain.
