Now we can see how well the rule corresponds with people’s reported acceptable ages.Men’s preferred minimum partner age: Let’s start with minimum age preferences reported by heterosexual men.
Only twice has he become involved with women whose ages were outside the rule’s guideline.
Women’s preferred maximum partner age: Examining maximum preferences, again the rule is more lenient, offering an age range with which most people are not comfortable.
The rule states that it is acceptable for 30-year old women to date men who are up to 46 years old, but in actuality, 30-year-old women state that their max acceptable partner age would be less than 40 (around 37).
According to the rule, for example, a 30-year-old should be with a partner who is at least 22, while a 50-year-old’s dating partner must be at least 32 to not attract (presumed) social sanction. Does it match our scientific understanding of age-related preferences for dating? Researchers Buunk and colleagues (2000) asked men and women to identify the ages they would consider when evaluating someone for relationships of different levels of involvement.
People reported distinct age preferences for marriage; a serious relationship; falling in love; casual sex; and sexual fantasies. Based on the figures Buunk and colleagues (2000) provided (and thus the numbers are only informed approximations), I replotted their data superimposing the max and min age ranges defined by the half-your-age-plus-7 rule.
