“Some people—those with high levels of neuroticism, need for closure, and obsessive-compulsive disorder—find uncertainty particularly aversive. Neuroticism is a personality trait characterized by a pattern of negative affect, anxiety, fear, and rumination. When people high in neuroticism are exposed to uncertain feedback compared to negative feedback, the nervous system delivers an outsize emotion-laden response.17 As psychologists Jacob Hirsh and Michael Inzlicht note, people scoring high in neuroticism “prefer the devil they know over the devil they do not know.” The implications of neuroticism for mental health are tremendous, with some researchers going so far as to argue that neuroticism is the common core of all forms of psychopathology!”
