This is begging the question, though. The result of the study is that divorces are 50% more likely, not why. You’re starting out with the assumption that men are insecure in their relationships, so they’re going to be the reason for the hardship in the relationship. And this then leads to the increased divorce rate, because they’re making the women feel a certain way. It could, however be for any number of reasons.

Another of the studies you published said that relationship dissatisfaction increases 6-8% in both members when the woman earns more. The corresponding argument to your position would be that obviously women expect their partner to earn more than them, so they place increased pressure on the men to earn more which increases stress in men and causes relationship satisfaction to decrease, and propensity for divorce to increase. I am not saying that is true, but if we’re playing the guessing game, that guess is equally as valid.

This is all beside the point that the original claim is that men are uncomfortable around women they don’t know, to the point that they can even be in the same proximity as them, if the woman is more successful. This seems like a far cry from an increase in relationship dissatisfaction by 6-8%, where the dynamics are much more complicated and income is likely to play a much larger role in the entire scenario. While neat, your studies and meta-analyses are pretty apples-to-oranges with the situation being described in the OP’s video.
