Researchers identified Nevada, Louisiana, New York, and Texas as states with high levels of dark personality traits like narcissism and psychopathy. Factors such as poverty, crime, and inequality were linked to these traits. Vermont, Massachusetts, New York, and Maine scored lowest due to better societal conditions like education and healthcare. The study, conducted by the University of Copenhagen, surveyed over 144,000 Americans. States like California, Alabama, and Mississippi with high crime rates and poverty also showed high dark traits. Geographical isolation and cultural heritage were suggested as reasons for lower dark traits in Alaska, Oregon, and Rocky Mountain states. The study highlights the impact of societal conditions on personality development. (Dailymail)
