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).
Figure 2 clearly shows that the rule’s max-age guidelines for men do reflect real-world preferences.
The rule overestimates the perceived acceptability of men becoming involved with older women.
The rule underestimates women’s reported preferences in their 20s, but the gap between reports of what is socially acceptable and the rule itself widen over time. Let’s take a look at Demi Moore, who at times has been criticized for dating men who differ substantially from her own age.
Thus the rule for maximum ages is fairly ineffective at capturing what men actually believe is acceptable. Now let's apply the rule to actual dating behavior by examining George Clooney’s dating habits.By the time of their separation in 2011, however, Kutcher, then 33 had crossed the minimum threshold (31.5) defined by the rule. Curious outsiders are quick to judge when they can see a wide age gap between two romantic partners. In a world in which many social norms are often unspoken, the half-your-age-plus-7 rule concretely defines a boundary.But the rule does map perfectly onto actual reports of what is socially acceptable.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.
