So I suppose an alpha is someone who is popular with women right? The beta is someone who is not?

TRPillers also associate alpha traits with being dominant and confident while beta traits are being caring or something?

There is a problem with this dichotomy. You realize that there are several people out there who are not caring and might have dominant personalities but are still not getting laid, right? I've known confident people who were not popular with women. I'm not going to give personal anecdotes now since I'm sure nobody cares.

On the other hand I've known people who were not uber socially dominant and in fact might have been more "quiet" types and were very popular because...I don't know they had good looks and style or something.

Of course TRP has other funny labels like sigma, omega and whatever else, but in the end it seems like a shallow way to categorize people.
