A 2000 study found that the rule was fairly accurate at describing the minimum age of a woman that a man would marry or date. However, the rule was not found to be descriptive of the minimum age of a man that a woman would marry or date, nor (by reversing the formula) of the maximum age that either sex would marry or date.<ref name=didonato>{{cite magazine|url=http://www.psychologytoday.com/blog/meet-catch-and-keep/201405/the-half-your-age-plus-seven-rule-does-it-really-work|title=The Half-Your-Age-Plus-Seven Rule: Does It Really Work? |magazine= Psychology Today|date=2014 |access-date=5 July 2014}}</ref>

This rule implies that the younger individual should be at least 14 years older than the difference between the two ages<ref>{{math|''Y'' ≥ ''Z''/2 + 7}} implies that {{math|''Y'' ≥ (''Z''−''Y'') + 14}}.</ref> and the older individual should be at least 14 years older than twice their age difference.<ref>{{math|''Y'' ≥ ''Z''/2 + 7}} implies that {{math|''Z'' ≥ 2×(''Z''−''Y'') + 14}}.</ref>
