30 dating 20 year old
Those age preferences consistently hover around the values denoted by the rule (the black line).
If anything, in practice men are than the rule would designate appropriate.
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.
As you can see from the graph, one partner exceeded the rule’s calculated acceptable maximum age, while Ashton Kutcher’s age fell short of the socially-acceptable minimum age when they first started dating in 2003.
With some quick math, the rule provides a minimum and maximum partner age based on your actual age that, if you choose to follow it, you can use to guide your dating decisions.
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?
Men do not show a linear increase in maximum age preference that matches the rule’s predictions.
In general, the figure shows that women are reporting minimum age preferences that the rule’s predictions.
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.
Women’s preferred maximum partner age: Examining maximum preferences, again the rule is more lenient, offering an age range with which most people are not comfortable.
The rule states that it is acceptable for 30-year old women to date men who are up to 46 years old, but in actuality, 30-year-old women state that their max acceptable partner age would be less than 40 (around 37).
