Sexual orientation continues to be an explosive issue in American classrooms. Increasing the political knowledge of students can reduce the volatility of this explosive issue by increasing tolerance toward the lesbian, gay, bisexual, and transgender community. This relationship between political knowledge and political tolerance has been recognized since Stouffer's seminal work (1955) examining respondents' tolerance toward unpopular groups. Since then, a number of political scientists have worked to further our understanding of the link between political knowledge and political tolerance. This manuscript expands upon the existing literature by examining the effect of political knowledge on political tolerance toward same-sex marriage equality using 10-minute lectures involving the U.S. Constitution. Findings will show that significant changes can be made to political tolerance levels by using a limited amount of time and information to increase the political knowledge of survey respondents.
