This study examined Big Five and Dark Tetrad personality perception for 56 characters from the popular TV show Game of Thrones—and the book series that inspired it, A Song of Ice and Fire—by 309 fans recruited from three relevant subreddits. Specifically, we examined consensus—the extent to which multiple perceivers (participants) rate one or more targets (characters) similarly—and projection (a.k.a. assumed similarity)—the extent to which perceivers (participants) see targets (characters) as they see themselves. Using cross-classified structural equation models (CC-SEMs), we found that consensus correlations were significant for all Big Five and Dark Tetrad traits, ranging from .54 for narcissism to .83 for agreeableness (M = .66, SD = .10). Projection slopes were positive (range: 0.07 to 0.29; M = 0.15, SD = 0.06) and significant for all traits except conscientiousness and open-mindedness. Thus, raters reliably assumed that characters were similar to themselves on 7 of 9 traits. Exploratory sex-differences analyses showed no sex-of-character effects, but significant sex-of-perceiver effects for conscientiousness, open-mindedness, and Machiavellianism; women perceived characters to be higher on these traits than men. In addition, women (vs. men) rated themselves as higher on extraversion, agreeableness, and conscientiousness, but lower on Machiavellianism. We also present rankings for characters with the highest and lowest scores on each trait. Broadly, this work is important not only for understanding how our perceptions of personality generalize to fictional characters, but also how we use fiction characters—and our perceptions of their personalities—to better understand our own social world.
