A striking new study published in PNAS has mapped where people with so-called “dark” personality traits—such as psychopathy, narcissism, and everyday sadism—are most likely to reside, linking these traits to broader social conditions such as poverty, inequality, and violence. The findings, drawn from multiple datasets and encompassing 1.8 million individuals across 183 countries and 144,000 participants in the United States, offer new insights into how environment and society can shape individual psychology (NewsNationNow).

A sweeping new global study shows that people living in societies plagued by corruption, inequality, poverty, and violence are significantly more likely to develop what psychologists term “dark” personality traits, including psychopathy, narcissism, and machiavellianism—a finding with profound implications for social policy and Thai society. Researchers from the University of Copenhagen, analyzing data from nearly 2 million individuals across 183 countries, report that social adversity is a strong predictor of psychological tendencies towards selfishness, aggression, and exploitation, raising key questions about how governance and environment shape the character of entire populations (Phys.org, news.ku.dk).
