An almost linear relationship between how much money a man makes and how likely he is to be unfaithful to his wife

This jumped out to me from 8:00 in the first video lecture. Wow! This of course could be explained in a number of different ways, am enjoying Michael’s presentation of anomalies that don’t seem to be well explained by what might be called our ‘folk psychology’ our intuitive ideas about how the mind works.

I googled “linear correlation more money a man makes less likely they are to remain faithful” and the third result that came up was @memills’s post on his Psychology Today blog.

The men that women generally most desire – powerful, high status men – are the very men who are the least likely to remain faithful to their wives. A man’s income level and the probability that he will be unfaithful is almost a perfect linear correlation. If a woman wants a faithful husband, she would do better to marry a taxi driver than a surgeon.

From the above article. I’ve googled for a study that shows this, would be cool to see the evidence for this, haven’t found a study yet though.

Another article that is referenced at the end of @memills article talks about this.

Most research does show that making more money is associated with having more affairs. In a 2001 study using a nationally-representative sample of the USA, David Atkins and his colleagues found people making more than $75,000 were 1½ times more likely to have an affair compared to those making less than $30,000. In that same study, people with graduate degrees were 1¾ times more likely to cheat on their spouses than those who did not graduate high school. A lot of other evidence points to high status people having extra-marital sex, but interpreting this can be tricky. Does achieving high status cause us to desire an affair, or do the same personality traits that cause us to achieve high status also cause us to be more likely to have affairs? It’s probably a little bit of both.

This article references this study but I can’t past the paywall.
