Scientific data does show a notable, population-wide shift in human behavior and personality traits following the pandemic. Here are two prominent studies for your review, plus the Pew Research Center Study, thrown in for extra measure. 1. The FSU College of Medicine "Pandemic Personality" Study The Findings: The study found statistically significant population-wide declines in Agreeableness (the capacity for empathy, trust, sympathy, and cooperation) and Extraversion (sociability and the desire to seek out others' company) by 2021/2022. The shifts were so severe that researchers stated the population experienced the equivalent of a decade of normal personality alteration compressed into just two years. Younger adults were hit hardest, showing sharp increases in neuroticism paired with a steep drop in overall friendliness and compliance with social norms. 2. The College Student Cognitive Empathy Study. The Study: Published in the Journal of American College Health (2022), this longitudinal study tracked college students' psychological well-being and empathic capacity immediately before and during the pandemic phases. The Findings: The researchers observed a significant decline in cognitive empathy (the psychological capacity to take another person's perspective or understand their mental and emotional state). This degradation of perspective-taking directly mirrors the "colder" and more "detached" behavior observed in the general public, as individuals became structurally less capable of processing or caring about the experiences of those around them while battling their own chronic stress and isolation. The Pew Research Center also reveals that 47% of American adults explicitly report that public human behavior became significantly ruder and more aggressive since the onset of the pandemic.
