Yuck! The Science of Disgust

The podcast explores the psychology of disgust, examining its influence on personal relationships, values, and political manipulation. David Pizarro, a psychologist at Cornell University, discusses how disgust, initially evolved to protect us from pathogens, now shapes our perceptions and behaviors in unexpected ways. Examples include Nixon's sweaty appearance impacting the 1960 presidential debate, the debunked rumor of immigrants eating pets affecting political discourse, and the use of disgust in Nazi propaganda. The conversation highlights disgust's connection to homophobia, moral judgments, and even outcomes in the criminal justice system, noting how it can be weaponized in public life. Pizarro also shares personal experiences and research findings, revealing the emotion's complex role in shaping our worldviews and actions.
