In the new study, the authors suggested that inferring personality from facial features, especially traits that signal a threat or potential harm, could be an adaptive mechanism.<\/p>\n
“Inferring personality from faces without any concrete source of information might be an evolutionarily adaptive trait,” they wrote.<\/p>\n

The study also tested whether participants could detect traits from the “big five” personality model\u2014traits like agreeableness, extraversion, and conscientiousness. Results here were mixed. Agreeableness, which includes qualities like trustworthiness and warmth, was the most consistently identifiable of the big five, especially in male faces.<\/p>\n
Interestingly, participants consistently struggled with identifying openness and neuroticism\u2014two traits that were actually misidentified more often than not. Similarly, extraversion was only accurately detected in women’s faces, not men’s.<\/p>\n
Cultural differences and similarities<\/p>\n
What sets this study apart from earlier research is its inclusion of both WEIRD (Western, Educated, Industrialized, Rich, and Democratic) and non-WEIRD populations.<\/p>\n
To test whether personality traits are visible in people’s faces, researchers used composite images from the Faceaurus database, developed by psychologist Nicholas Holtzman. These images were created by blending the faces of real people who had scored very high or very low on traits like psychopathy, narcissism, or agreeableness.<\/p>\n
Although the faces were based on American participants, they were shown to people in both the U.S. and Turkey to see if judgments held up across cultures.<\/p>\n
“All dark triad traits were found to be visible in prototypical faces,” the study’s authors wrote. “This finding replicated across three samples spanning WEIRD and non-WEIRD contexts.”<\/p>\n
Despite this, the composite images were still only made to look Caucasian, as a result study authors noted that future research should use a more diverse set of images.<\/p>\n

\n How to spot dark triad personalities<\/p>\n
While these results show that the dark triad can be identified with looks alone, psychology professor Jason Walker of Chicago’s Adler University who has studied the dark triad told Newsweek that there are other ways to detect a dark triad personality.<\/p>\n
“Stop mistaking charm for character. Narcissists are often highly performative and skilled at telling people what they want to hear,” Walker said.<\/p>\n
“Watch how they treat those with less power. True character is revealed in how someone engages with people they don’t need to impress.”<\/p>\n
He said that while looks may open the door, trust should be earned through true personality, not charisma or curated image.<\/p>\n
“Pay attention to subtle power plays\u2014like monopolizing credit, gaslighting dissenters, or constantly shifting blame. These are not quirks, they’re red flags,” Walker explained.<\/p>\n
