People do make judgments about other people, like about how healthy their personalities are.
But stop and think: what are the components of a healthy personality? This is not just a food-for-thought question, but a real research topic, at the likes of the Personality Change Lab at the University of California-Davis.
And after a lot of work, lab members think they have the five key variables: neuroticism, extraversion, openness to experience, agreeableness and conscientiousness. Before you start to assess yourself and others on these scales, listen to our interview with lab director Wiebke Bleidorn and fellow researcher Chris Hopwood.
