This comic strip summarizes 5 concepts from social psychology: 1) Diffusion of responsibility, where people passing a beggar don't help assuming others will; 2) Stereotyping, where a shopkeeper sees a tattooed man as a gangster; 3) Affective forecasting, where the shopkeeper inaccurately predicts being robbed; 4) First impressions, where a woman rejects the man thinking he's unattractive; 5) False consensus effect, where the beggar assumes no one will help like everyone else. The comic shows how appearances and assumptions can lead people to make inaccurate judgments of others.
