Editing Infidelity (section)

===Strategic pluralism theory===
[[Sociosexual orientation#Strategic pluralism theory|Strategic pluralism]] is a theory that focuses on how environmental factors influence mating strategies. According to this theory, when people live within environments that are demanding and stressful, the need for [[bi-parental care]] is greater for increasing the survival of offspring. Correspondingly, monogamy and commitment are more commonplace. On the other hand, when people live within environments that encompass little stress and threats to the viability of offspring, the need for serious and committed relations is lowered, and therefore [[promiscuity]] and infidelity are more common.<ref name="Schmitt, D.
