Intelligent people are better judges of the intelligence of others (psypost.org)

A German study in Intelligence found that participants who scored higher on cognitive ability were more accurate at judging the intelligence of others from one-minute videos. The study also linked better emotion perception and higher subjective life satisfaction with more accurate judgments, while gender and traits like empathy or openness were not consistently associated. The authors suggest that accurate perceivers may rely on clearer, more informative behavioral and language cues, though the video format and sample may limit real-world applicability.
