The Horizons Project and Beyond Conflict partnered to create this video on ‘The Brain on Authoritarianism’ to support broad-based “united front” organizing in response to the rising authoritarian threat in the US and globally. Better understanding the brain’s response to fear, toxic othering, and threats to social identity will help pro-democracy organizers to confront the authoritarian playbook and come together across difference to work more effectively towards a multi-racial, pluralistic, and inclusive democracy.
