Fear of the dead, fear of death: is it biological or psychological?

Abstract The claim that aversion to dead bodies reflects a non-conscious response to objective physiological danger is thoroughly examined. No evidence is found for the idea that corpses are especially dangerous as potential sources of contamination. While reactions to dead bodies vary greatly among humans, depending on personal and cultural factors, fear of the dead is tied to the awareness of mortality. Humans react to the presence of death by transforming the dead, physically and psychologically.
