What is the similarity and infection?

"Similarity and infection" is a blanket used to indicate ways of thinking that sees similar objects to metaphysically attached (similarity) and objects that once come into contact as always in contact (infection). The term is used in cognitive psychology and anthropology for these universal tendencies in human reasoning. Anthropologists conducted hundreds of cultures; Including primitive tribal cultures, basically unchanged for thousands of years and found that similarity and infections are completely universal. For example, to curse someone, one could get a lock lock and disappear. Because the hair comes from a person and even grew from them, it is assumed that it will retain the essence of this person. What the hair owner affects. This principle is obviously symbolized by voodoo dolls, but in cultures around the world there are finer variations of similarities and infections.

In one experiment, postgraduate students refused to drink tea that was mixed with a disinfected fly, even though they offered money to do so. These and similar experiments and observations show that the similarity and thinking based on infection is not only a cultural delay from more primitive times, but a rooted aspect of human cognitive processing that is coded in our genes. Similarity and theory based on infection are heuristics-TJ. The rules-which helped our ancestors survive in the harsh world in which our species developed. Most of these heuristics were USEFUL-for example, it is really stupid to consume a fresh-looking piece of food if it is in a pile of rotting food. But under various conditions, especially modern conditions, this heuristics is no longer valid.
