The Nutty Professor

  • This group tended to be introverted when sober but showed an increase in Extraversion and decrease in Conscientiousness when drunk
  • Compared to the other groups, this cluster had the biggest discrepancy between reported sober and drunk five-factor model traits
  • However, this group was not associated with having experienced more alcohol-related consequences
  • While the personality change for this group was most dramatic, this cluster was not associated with increased harm, possibly due to the fact that the mean drunk levels for these traits, while different from their sober levels, were still within normal range
