A question for the ages: Are you stuck with yourself?
Plenty of researchers who study personality would answer in the affirmative. For a long time, the study of personality was stuck in two extremes: Some psychological scientists argued that your personality is so stubborn that it forms once and for all in early childhood, staying essentially the same from first grade into adulthood. (“Personality Set For Life By 1st Grade,” was one headline on the matter in 2010.) You are who you are, and there is not much that you can do about you. Others would say that personality is so unstable that trying to measure any change is hardly worthwhile. Lately, personality psychologists have taken a more moderate view: If personality traits do change, they change slowly, and the overall difference over time tends to be modest.
