Genetic scores linked to depression and neuroticism are associated with lower voter turnout

A new study suggests that your DNA might have a say in whether you show up at the polls. Researchers analyzing data from more than 50,000 individuals have found that genetic predispositions linked to depression and neuroticism are associated with lower rates of voter turnout.

The team used advanced DNA scoring methods to examine how genetic factors related to health and personality traits might predict political participation. Their findings indicate that people with higher genetic scores for these conditions are less likely to cast a ballot.

The research does not claim that genes alone determine voting behavior. Instead, it points to a complex relationship between biology, mental health, and civic engagement. Depression and neuroticism can affect energy levels, social interaction, and a person's sense of efficacy, all of which influence whether someone participates in elections.

Experts say the results could help explain persistent gaps in voter turnout that go beyond income, education, or geography. If certain health and personality traits, partly shaped by genetics, make voting harder, then making the process more accessible could help more people take part.

The study adds to a growing body of work exploring how psychological and biological factors shape political behavior. It also raises questions about how campaigns and policymakers might better support citizens who face internal barriers to voting.
