Legalizing Same-Sex Marriage Will Increase Prevalence of Homosexuality:
Research Provides Significant Evidence
by Trayce Hansen, Ph.D.
An accumulation of research from around the world finds that societies which endorse homosexual behavior increase the prevalence of homosexuality in those societies. The legalization of same-sex marriage—which is being considered by voters in several U.S. states—is the ultimate in societal endorsement and will result in more individuals living a homosexual lifestyle.
Extensive research from Sweden, Finland, Denmark, and the United States reveals that homosexuality is primarily environmentally induced. Specifically, social and/or family factors, as well as permissive environments which affirm homosexuality, play major environmental roles in the development of homosexual behavior...
A Danish research investigation studied two million adults living in Denmark, a country where same-sex marriage has been legal since 1989. This study uncovered a number of specific environmental factors that increase the probability an individual will seek a same-sex rather than an opposite-sex partner for marriage.
For Danish men, the environmental factors associated with higher rates of homosexual marriage include an urban birthplace and an absent or unknown father. Significantly, there was a linear relationship between degree of urbanization of birthplace and whether a man chose homosexual or heterosexual marriage as an adult. In other words, the more urban a man's birthplace, the more likely he was to marry a man, while the more rural a man's birthplace, the more likely he was to marry a woman.
For Danish women, the environmental factors related to increased likelihood of homosexual marriage include an urban birthplace, maternal death during adolescence, and mother-absence. Interestingly, this Danish research finds that urban birthplace and separation from the same-sex parent both were associated with same-sex marriage for men as well as women. (The latter finding supports psychological theories that have long asserted homosexuality is related to childhood problems—real or perceived—with the same-sex parent). In summary, this study finds that environmental factors that contribute to the development of homosexuality can be social and/or familial.
Finally, an American research study—the most comprehensive and representative survey of sexual behavior in America—reported its findings concerning homosexuality. The results of this study also support an environmental theory of homosexuality, not a genetic one. In particular, this survey identified specific types of environments that increase the likelihood of homosexual behavior. The authors describe these environments as "congenial" to the development of homosexuality.
