The evolution of neuroticism in psychology unravels the development and adaptive significance of emotional sensitivity throughout human history. Neuroticism, a personality trait characterized by heightened emotional reactivity and vulnerability, can be traced back to our evolutionary past. In ancestral environments, individuals with a tendency towards neuroticism may have been more attuned to potential threats, enabling them to anticipate and respond to dangers effectively. However, in modern societies, the same heightened emotional sensitivity can lead to maladaptive responses and increased vulnerability to psychological distress. Understanding the evolution of neuroticism sheds light on the interplay between genetics, environment, and the complex dynamics of emotional regulation.
