According to the Merriam-Webster dictionary, '''incest''' is "[[sexual intercourse]] between persons so closely related that they are forbidden by [[law]] to [[marry]]; also:  the statutory [[crime]] of such a relationship."<ref>[http://www.merriam-webster.com/dictionary/incest Incest - definition by the online Merriam-Webster dictionary]</ref> [[Sociologist]]s call incest "the universal [[taboo]]", due to the fact that every [[human]] [[society]] condemns it, regardless of their other [[belief]]s. Incest almost always occurs among estranged relatives, due to a [[psychological]] effect called reverse sexual imprinting. Essentially, if someone is raised from [[birth]] around someone they know, instead of becoming sexually attracted to that person, they become protective of that person. Sons tend to be protective of their [[mother]]s, and [[father]]s tend to be protective of their [[daughter]]s for this reason. The reason the incest taboo is embedded so deeply into human [[instinct]] is probably because of the significantly higher risk of birth defects among conception between direct relatives. Between [[cousins]], the probability is double the normal rate (of 4%)- if [[reproduction]] among relatives gets any closer than that, the probability spikes dramatically.
