In a speech given at a TED
conference filmed in May, psychologist David Pizarro details the findings of
his study on the emotion of disgust and how it might play a role in our
political decisions. Pizarro is
currently an associate psychology professor at Cornell University and recently
conducted a survey in which he measured a person’s tendency to be disgusted and
how it might affect their political leanings.
He was able to engage the audience by describing the exact process he
went through to conduct the survey, which involved showing the exact same
images in the presentation that he used to illicit a disgusted response during
the survey, such as blood and vomit. In
addition, he repeatedly used humor as a way to keep the audience entertained
yet focused on the topic at hand.
Pizarro eventually determined that the more likely a person was to be
disgusted, the more likely they were to be politically conservative.
Beyond simply stating this conclusion though,
Pizarro also posed a specific question to his audience, most of whom were TED
speakers themselves and therefore were familiar with the scientific process
Pizarro used to conduct his study.
Ultimately, he questioned why we tend to view things like gay marriage
as disgusting, even though disgust as an emotion is meant to protect us from
disease and potential contamination. By providing statistical evidence, Pizarro
forces his audience to question their own method of political decision-making
and to be wary of those trying to manipulate the emotion of disgust as a tool
for political gain.
