Being a Good Samaritan might be genetic, research shows. The phrase "Good Samaritan" refers to a parable from the Bible in which a traveler stops to help a wounded person when others had not. Scientists believe that the difference between those who tend to help others and those who do not might be a gene variation in the 5-HTTLPR region, which is related to social anxiety. This gene region is responsible for transmitting serotonin, a chemical in the brain that regulates mood. People who have higher levels of anxiety around other people might be less likely to intervene to help others because of their social discomfort.
