Regions where voters have more neurotic personality traits were more likely to vote for Donald Trump in the United States or for the Brexit campaign in the United Kingdom, revealing a new trend that could help explain the rise of fearmongering populist political campaigns across the world, according to new research published in the journal Social Psychological and Personality Science.
Researchers analyzed personality traits from online surveys of more than 3 million people in the United States and more than 417,000 people in the United Kingdom. Election data was compiled from public sources.
"Our study reveals how neuroticism or psychological hardship is shaping the global political landscape," said lead study author Martin Obschonka, PhD, a psychologist and associate professor at Queensland University of Technology in Australia. "One could also call this 'irrational' voting behavior because the surprising success of Trump and Brexit weren't predicted by models that relied on a rational understanding of voters."
