Sushi is the Gay Marriage of Food
I recently gave a talk at the American Enterprise Institute. Jonathan Rauch, who writes often on gay issues, asked me how moral attitudes could have changed so quickly on gay marriage. People often seem to think that if I’m saying that moral foundations are innate and evolved, then our moral beliefs are innate and can’t change. In response, I offered the example of sushi. For centuries Americans thought it was disgusting to eat raw fish. But once some people started doing it more visibly, and people habituated to it, the disgust factor decreased and sushi became OK. This short clip offers my general explanation of one way that morals change rapidly.
