20 years ago, a man saved her life, by putting his own life in danger. He ran across 4 lanes of freeway traffic, to bring her to safety after being in a car accident that could have killed her. The man was a total stranger, who took off after making sure she was okay – she never even got his name.

With this data, Marsh wanted to research whether or not it was different for highly altruistic people as well. Marsh tested people who showed a huge level of altruism: people who gave away their kidneys to complete strangers without any gain. What Marsh found was that these people are complete opposites of psychopaths: 1) they are better at detecting other people’s fear as well as detecting their distress. 2) The amygdala is hyperactive. 3) Their amygdala is larger than average by 8%. This led to the observation of the “Caring Continuum”, which is a scale showing that on one end psychopaths are and on the other, are extreme altruistic
