The science of Slutology continues to advance and here I present another interesting paper worth perusing.
Nothing here that's new under the sun but it's nice to see science proving what common sense asserts. Some choice quotes from the paper:
This wide variation in reports of frequency of infidelity and non-paternity may reflect differences in reporting accuracy regarding these delicate matters. In a US study, women (but not men) tended to underreport their number of sex partners unless they believed lying could be detected (Alexander & Fisher, 2003). Another study of American women found that when asked face-to-face about number of sexual intercourse partners in the past year, 1.08% of married women reported infidelity whereas when the same question was asked through a computer questionnaire, 6.13% of the married women reported having sexual intercourse with more than one man (Whisman & Snyder, 2007). [Ed: Ouch! That's almost a sixfold increase!]
Values: Smith (1994) found permissive sexual values to be associated with infidelity. Over three-quarters of Americans who did not think extramarital sexual relations are “always wrong” reported engaging in infidelity, whereas those who said it was “always wrong” reported a 10% rate. Being politically liberal, highly educated, and sexually permissive before marriage was related to casual sexual mores. At least two studies have discovered that the more religious people were, the less likely they reported engaging in extramarital sexual relations (Buss & Shackelford, 1997; Whisman & Snyder, 2007)
Physical attractiveness, as determined by independent raters, was not a predictor of the number of times US college women engaged in extra-pair sex [ED](Gangestad & Thornhill, 1997). In fact, women with low self-esteem tended to have had more sex partners and one-night stands (Mikach & Bailey, 1999). Similarly, adolescent girls who had had many sex partners rather than few or none tended to have lower self-esteem and more depression (Spencer et al., 2002).
One factor that seems to affect infidelity across cultures is low paternal investment. For example, in matrilineal societies paternal investment typically is low, often giving rise to the avunculate, and infidelity and divorce tend to be common (Daly, Wilson, 1983; van den Berghe, 1979). Similarly, where the wife is relatively independent economically of the husband, marital bonds tend to be weak (Friedl, 1975; Goode, 1993; Seccombe & Lee, 1987) and infidelity by the wife is relatively common (van den Berghe, 1979).Nothing is certain in life and picking a good partner is hard but an attractive girl, who loves her daddy, and is from a good, stable, conservative-religous family is a pretty safe bet.
