Personality Types: working with people who aren't you

The academically validated model from personality psychology, five broad traits: Openness (to experience), Conscientiousness (organized vs. spontaneous), Extraversion (social energy direction), Agreeableness (cooperation vs. competition), Neuroticism (emotional volatility vs. stability). Each is a dimension, not a category. McCrae and Costa's research from the 1980s onward, replicated across cultures. Unlike Myers-Briggs, the Big Five has strong empirical support and is the working vocabulary of modern personality science.
