The concept of 'emotional intelligence' (EI), popularized by Daniel Goleman in the 1990s, has been both celebrated and scrutinized within academic psychology. Proponents argue that EI, defined as the ability to perceive, use, understand, and manage emotions, predicts success in interpersonal domains beyond traditional cognitive intelligence (IQ). However, critics contend that the construct is poorly defined and overlaps excessively with personality traits such as agreeableness and neuroticism. Recent meta-analyses suggest that while ability-based measures of EI show modest incremental validity in predicting job performance, self-report measures are often confounded with mood and self-esteem. Consequently, researchers advocate for a clearer distinction between trait EI and ability EI, urging that future studies employ rigorous, performance-based assessments to validate the construct's unique contribution to human behavior.
