Man is capable of changing the world for the better if possible, and of changing himself for the better if necessary. The work of Barbara Fredrickson offers further evidence of a positive attitude as promoting resilience. Fredrickson’s research suggests we are better able to solve problems when we are in a positive frame of mind because a positive mind frame broadens our thought–action repertoire. Historically, research has been correlational, showing a relationship between social support and resilience where the direction of influence was not clear. Most people understand that people get sick from others who are have a contagious illness. However, research shows that there is a contagion effect for illnesses that are not transmitted biologically. Community-level support networks are very important sources of resilience or pathology for officers. A cornerstone of resilience is sleep. The lack of sleep is so damaging, sleep deprivation has been used as a form of torture.
