It is a human impulse to mimic others. Without realizing it, we yawn when we see other people yawning. When someone in a crowd looks up, other people in the crowd look up as well. In social situations, people choose to “go along” with others depending on the degree of pressure the social influence has on the individual. If deviating from another person’s beliefs has social consequences (e.g., isolation), people will be more likely to conform. For instance, you may have experienced this in high school: when a person is being bullied, the bystander may feel sorry for the individual being bullied, but fear that they may be bullied themselves or become socially isolated. As a result, the bystander may be more likely to “go along” with the bullying, even though they are against it.
