This rules states that by dividing your own age by two and then adding seven you can find the age boundary: Take your age, subtract 7, and double it.
So for a 24-year old, the upper age limit would be 34 (i.e., 17 * 2).
He approached the line with two other partners, but is well within the threshold in his marriage with Amal Alamuddin. The minimum rule (half-your-age-plus-seven) seems to work for men, although the maximum rule falls short, failing to reflect empirical age-related preferences.
How well does the rule capture women’s preferences?
Clooney has been scrutinized at times for dating younger women, though not consistently, and this pattern is nicely reflected in a graph of his own age, his partners’ ages, and the rule’s calculations for minimum and maximum acceptable ages.
Only twice has he become involved with women whose ages were outside the rule’s guideline.
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.
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.
Even when fantasizing, such women’s minimum age preference remains over 30.
The rule’s calculated minimum acceptable partner ages seem to fit men better than women.
Figure 2 clearly shows that the rule’s max-age guidelines for men do reflect real-world preferences.
