Terror Management Theory
Nearly everyone fears death. How that fear influences human thinking and behavior is the focus of terror management theory (TMT) research. According to TMT, death anxiety drives people to adopt worldviews that protect their self-esteem, worthiness, and sustainability and allow them to believe that they play an important role in a meaningful world. Some of these views lead to troubling actions.
According to TMT, people need to insulate themselves from their deep fear of living an insignificant life destined to be erased by death. One path to address this fear is to assure themselves that they are part of an important group. This desire to reinforce cultural significance in the face of death often results in displays of prejudice based on the belief that the group with which one identifies is superior to others. In this way, people confirm their self-importance, at least to themselves.
TMT proposes that individuals are motivated to develop close relationships within their own cultural group in order to convince themselves that they will somehow live on—if only symbolically—after their inevitable death.
The Fear of Death
Terror management theory was developed by Jeff Greenberg, Sheldon Solomon, and Tom Pyszczynski and expanded in their 2015 book, The Worm at the Core. But the concept is built on the earlier work of anthropologist Ernest Becker, whose 1973 book, The Denial of Death, argued that the majority of human actions are undertaken primarily as a means to ignore or evade death.
Most psychologists consider TMT to be a sort of evolutionary trait. Humans naturally became aware of dangerous threats as a means of preserving their lives and continuing their gene pool. The deep existential anxiety that comes with that knowledge is an unfortunate byproduct of this evolutionary advantage.
The Ramifications of Terror Management
Terror Management Theory suggests that large groups, and even entire societies, may make decisions, or put them off, primarily to gain comfort from avoiding thoughts of death or reassurance that their ideas will live on after they are gone. Research finds that this plays out in some unexpected ways, both beneficial and potentially hazardous.
