It takes one to know one: Interpersonal sensitivity is related to accurate assessments of others' interpersonal sensitivity.

Neither gender nor acquaintanceship was directly related to accurate judgments of interpersonal sensitivity, nor did either variable moderate the it-takes-one-to-know-one effect.

Abstract

Interpersonal sensitivity (emotional and social) is the ability to accurately assess others' abilities, states, and traits from nonverbal cues. The authors predicted that individuals' interpersonal sensitivity would be related to accurate judgments of friends' interpersonal sensitivity. Fifty participants were recruited, each bringing a friend to participate in performance-based, self-report, and other-rating measures of emotional and social sensitivity. Interpersonal sensitivity was related to accurate judgments of others' interpersonal sensitivity (the "it-takes-one-to-know-one effect"). Neither gender nor acquaintanceship was directly related to accurate judgments of interpersonal sensitivity, nor did either variable moderate the it-takes-one-to-know-one effect.
