Possibility of personality changes after the pandemic - Video

Despite a long-standing hypothesis that personality traits are relatively impervious to environmental pressures, the COVID 19 pandemic may have altered the trajectory of personality across the United States, especially in younger adults, according to a new study published this week in the open-access journal PLOS ONE.

In the new study, the researchers used longitudinal assessments of personality from 7,109 people enrolled in the online Understanding America Study. They compared five-factor model personality traits-neuroticism, extraversion, openness, agreeableness and conscientiousness-between pre-pandemic measurements and assessments early or later in the pandemic. A total of 18,623 assessments, or a mean of 2.62 per participant, were analyzed.

Participants were 41.2% male and ranged in age from 18 to 109.

Consistent with other studies, there were relatively few changes between pre-pandemic and 2020 personality traits, with only a small decline in neuroticism. However, there were declines in extraversion, openness, agreeableness, and conscientiousness when 2021-2022 data was compared to pre-pandemic personality. The changes were about one-tenth of a standard deviation, which is equivalent to about one decade of normative personality change. The changes were moderated by age, with younger adults showing disrupted maturity in the form of increased neuroticism and decreased agreeableness and conscientiousness, and the oldest group of adults showing no statistically significant changes in traits.
