A new theory proposes that social identity and policy positions compete to shape voter choice. This model explains why voters often select candidates whose policies contradict their own interests, as people prioritize their self-image and social media signals over the practical benefits of voting.
Researchers propose a new model predicting voter choice that prioritizes identity over policy issues. This approach aims to improve election outcomes predictions by considering how voters' personal identities influence their voting decisions.
