This conversation reminds me of the MGTOW conversation where everyone is coming at it from different angles and different experiences.
It is true that everyone thinks of themselves as alpha, and no one identifies with beta because of judgment associated. On the other hand it is also true that every man has various levels of leadership in them.
And I think it is also true that leadership, and in particular leadership among men, is an attractive characteristic to women.
It is not really new info. Think back of the old Charles Atlas advertisement. Or the Back to the Future movies where the Dad is a wimp in the bad outcome futures but he is a confident self-controlled guy in the good outcome futures.
Basically, the PUA guys found out that this is still basically true, and that women still want this despite all of the modern talk of "toxic masculinity".
Further they found out that you can work on and improve in this area. Some ways it is just common sense things, like a firm handshake and looking the other man in the eye.
Or the square in the video, for example (which I found highly interesting and amusing). No one listened to the squeaky voice guy, but everyone listened to the man who talked slowly with a lower voice (this also comes out of the parenting 101 manual). Lower your voice if you want to command. It was a lesson I learned in the Navy.
Another thing to understand that these are all just factors, one of many. For example, as the video says, size helps. But clearly it is not the only factor, otherwise Andre the Giant would have been President of the US.
It is also, well known that short men have a major hurdle to overcome. Women, in general, do not like to be with men who are shorter than they are. That is just the way it is.
So what to make of all of this?
I think it is useful. If you want to more of a man among men. If you want to be more of a leader. If you want to be more attractive to women. This is helpful knowledge.
And while the PUA community discovered or re-discovered a lot of this stuff, clearly the application goes beyond simple pickup. It can be used in a business setting to get yourself viewed as more of a leader. It can make you more attractive to women, or to your wife. It is in effect basically in any social setting.
Is it important?
I think there are clearly other things more important such as character and integrity (referred to as "inner game" in the PUA community).
I would liken this to Moses and Aaron. Moses had the character and the integrity and God chose him as a leader. Unfortunately Moses did not have game and deferred to Aaron. Clearly the character and the integrity were the important part, but it might have been better for him if in addition he had his own game and not had to defer to his brother.
Note: I am aware that I used game here as a synonym for confidence, which is probably the #1 factor in game.
