Is neuroticism fueled by overthinking?

In a Trends in Cognitive Sciences Opinion paper published Aug. 27, psychologists present a new theory for why neurotic unhappiness and creativity go hand-in-hand. The authors argue that the part of the brain responsible for self-generated thought is highly active in neuroticism, which yields both of the trait's positives (e.g., creativity) and negatives (e.g., misery).
