A common rule of thumb, at least on the internet, is that it’s okay to be interested in someone “half your age plus seven” years.
According to this rule, it would not be creepy for a 30 year old to date a 22 year-old, but an 18 year-old would be off-limits.
To get 22, you divide 30 in half, leaving you with 15 remaining, and then add seven more to arrive at 22.The “half your age plus seven” rule of thumb probably helps you avoid being a creep, but is it accurate?Much to my surprise, when overlaying a line representing the rule of thumb on Kenrick and Keefe’s results (see red line in the figure below), you can see it closely matches the low end of the range (i.e., youngest preferred) for all but the oldest men.It is so funny to see how some social behaviors are exactly the same between France and the US, and others are completely different. Well, this was a big shock to me when I arrived in the US. I understood of course a man and a woman could be interested in each other in a romantic way, let me reassure you.One of the very obvious difference is the dating game. But I was not aware that accepting to go out to dinner with a man alone gave the signal that I was possibly romantically interested in him.Figuring out the high range of 46 requires knowing the math of a 46 year old.
