John Gottman is best-known for studying what causes marriages to break up. He hasn't said anything that hasn't been known for a few thousand years, but, these days, he's the one who's studied it the most. About 20 years, I think.
He found the biggest predictor of divorce is contempt. Actually there are four things: Criticism, Defensiveness, Contempt and Stonewalling. If you want, you can call them the Four Horsemen.
Contempt is the opposite of respect, and respect is based on gratitude and appreciation. What contempt is really saying is, "You're not good enough."
And the reaction to that attitude is going to be resentment and defensiveness, including the phrase, "Nope, I'm not going to do that..." You can end that phrase with, "...anymore."
There is always going to be a reaction to contempt, never good ones. So it mystifies me that some people think they can show contempt and ingratitude and expect something good to come out of it. Do they honestly think they can change behavior like that?
I know a man who was a mercenary, and he killed a lot of people, all of whom, in my opinion, deserved it. After he retired from it he became head of security in a pretty bad area. Whores, pimps, drug dealers, that kind of thing. He told them, you do your dealings over there, not here, and there will be no trouble. This is my territory and that is yours. He specifically used the word "respect" in taking to me. And, he told me, he never had any trouble with them, ever.
I see three main trends in the Manosphere, which means there are three main trends in society: Men Going There Own Way and men not getting married and having children.
Each of those is Stonewalling and saying "no," which means they are reactions to contempt and ingratitude.
The Third Trend is the PUA (Pick-Up Artist). This is based on revenge and contempt for women, contrary to the protestations of some well-known commentators. Of all the PUAs I have known, not one liked women. And every one of them screwed up his life unless he quit was he was doing.
Not long ago I read some articles about how some women are trying to draw out the courtship process to get free entertainment and food. The extent to which this is true, I do not know. Most women couldn't pull it off successfully.
But whether it is a little successful or a lot successful, it's showing contempt and disrespect for men, and zero gratitude and appreciation.
I know a man who went away to college when he was 18, and come not make it home for Christmas, since his home was a few thousand miles away. A woman he had met told him she'd pick him up and he could spend Christmas with her and her family.
She never showed up, never called, never explained or apologized, and I don't think he was ever the same. He was 18, alone, away from home for the first time, and got a rude awakening to what lies and disrespect really were like.
As for Men Going Their Own Way and not getting married and having children, the best explanation is that they feel they getting a bad deal - being treated contemptuously, without respect or gratitude, feeling that they are the objects of attempts to humiliate them.
Contempt is the attempt to humiliate someone. And the attempt to humiliate someone leads to the attempt at revenge. That's a repeatable science, and has been for thousands of years.
