The word homophily, in a literal way can be defined as “love for equals”; in a social environment it refers to the inclination of certain individuals to relate to others who are very similar to them. Therefore, it could be said that it is based on the basic element of communication that supports the exchange of ideas that frequently manifests between people defined as equals.

These similarities of which we speak allude to different attributes that these people may possess such as education, beliefs, social class, among others, that is to say that although on many occasions sexual connotations are attached to it, it does not always have to refer to this, due to to which it can be associated with a friendship that shares different hobbies, inclinations, tendencies, etc. that is, people with a union based on shared interests.

For its part, homophily harboring sexual connotations is used as an alternative word to homosexuality; term that was widely used in the 1950s and 1960s by different homosexual organizations and publications; therefore the groups existing in this period are known today as the homophile movement.

Then, in the late 1960s and early 1970s, in this context, the term homophily began to fall out of use thanks to the rise of gay liberation movements, to be replaced by new terms such as gay, lesbian, transgender and bisexual, however it should be noted that certain homophilic groups survived until 1980, 1990 and even 2000.

It was Karl-Günther Heimsoth, a German psychoanalyst, astrologer and author who coined the term homophily in his doctoral dissertation Hetero- und Homophilie in 1924, and it was from then on that the concept began to be widely used in sociology and other fields. fields.
