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.
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.
After 40, maximum age preferences for most categories remain lower than their 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.
In other words, while the rule states that 40-year-old women can feel comfortable dating 27-year-old men, this does not reflect the social preferences and standards of women.
Women in their 40s think that approximately 35 or older is acceptable for marriage or a relationship.
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).
What is the acceptable minimum age for your own (and others’) dating partners?
When this question comes up in conversation, someone inevitably cites the “half your age plus seven” rule.
Men do not show a linear increase in maximum age preference that matches the rule’s predictions.
