In a new study, Stanford psychologists examined why some people respond differently to an upsetting situation and learned that people’s motivations play an important role in how they react. Their study found that when a person wanted to stay calm, they remained relatively unfazed by angry people, but if they wanted to feel angry, then they were highly influenced by angry people. The researchers also discovered that people who wanted to feel angry also got more emotional when they learned that other people were just as upset as they were, according to the results from a series of laboratory experiments the researchers conducted.
…To learn how people react to upsetting situations and respond to others around them, the researchers examined people’s anger toward politically charged events in a series of laboratory studies with 107 participants. The team also analyzed almost 19 million tweets in response to the police shooting of Michael Brown in Ferguson, Missouri, in 2014. In the laboratory studies, the researchers showed participants images that could trigger upsetting emotions, for example, people burning the American flag and American soldiers abusing prisoners in Abu Ghraib prison in Iraq. The researchers also told participants how other people felt about these images. The researchers found that participants who wanted to feel less angry were three times more likely to be more influenced by people expressing calm emotions than by angry people. But participants who wanted to feel angry were also three times more likely to be influenced by other people angrier than them, as opposed to people with calmer emotions. The researchers also found that these participants got more emotional when they learned that others also felt similar emotions to them.
