Have you ever wondered why people split themselves up into certain groups? Why people like one person or one idea, but dislike another? Why do people disagree over politics and policies such as immigration or civil rights? This course uses the lens of psychology to explore the hidden forces that drive conflict, group loyalty, and decision-making in our society. Rather than debating specific policies, we will investigate the science of human behavior to understand what makes us "us" and them "them." Step back from the noise and learn how to navigate a complicated world with curiosity and critical thinking.
