For example, this sample of 60-year-old men report that it is acceptable to fantasize about women in their 20s, which the rule would say is unacceptable.But fantasies, of course, are not generally subject to public scrutiny and the rule is only designed to calculate what is socially acceptable —so this discrepancy is not necessarily a failure of the rule.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).Women’s preferred minimum partner age: Below are the data from Buunk et al.’s (2000) study on women’s minimum age preferences; the rule’s age calculations are represented by the solid line.In general, the figure shows that women are reporting minimum age preferences that the rule’s predictions.In Figure 1, the solid black line represents the rule’s calculation for minimum acceptable range.
The utility of this equation is that it lets you chart acceptable age discrepancies that adjust over the years. Let's examine it: How well does the rule reflect scientific evidence for age preferences?
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.
