You may be making two invalid assumptions: (1) that women themselves really know what they want, and (2) that they would honestly tell you.
Go visit the "skittles" link in the article.
The average woman has little use for "nice guys". Despite anything she says, she's biologically hard-wired to look for somebody who will protect and provide for her and her kids. A "nice guy" who can be pushed around by her, is of far less value than the SOB who will not accept being pushed around by anybody. The most-valued guy is the one who lots of women want (the "alpha male"), and the alpha male generally has the attitude of "if you don't treat me nicely, I can immediately replace you with another woman"
“The average woman has little use for “nice guys”. “
Who really wants an average woman? Has anyone considered that the average women and the alpha men have a purpose? They are mutually sucking leeches designed to draw one to the other and, in general, isolate and localize the poison that is...themselves.
Self-deluded pride enables them to feel like winners and write books telling others how to become a bigger child of hell than them.
Of course there are casualties along the way. The leeches have to feed off the decent in order to discover they hate the taste. The decent can learn from this. Or not.
