Most electoral democracies, including forty-three states in the United States,
deny people the right to vote on the basis of intellectual disability or mental illness. Scholars in several fields have addressed these disenfranchisements, including legal scholars who analyze their validity under U.S. constitutional law and international-human-rights law, philosophers and political scientists who analyze their validity under democratic theory, and mental-health
researchers who analyze their relationship to scientific categories.
