Assignment task: In Everything Is Obvious, Once You Know the Answer, Duncan Watts argues that our common sense explanations of how society works are often erroneous. How do Watts define common sense? Why did Stanley Milgram and his students have such a hard time walking up to strangers and asking for their seats on the subway in New York? Can you give an example of a common sense error you have made in your life or a common sense idea about something that might not be common sense for another person?
