I'm not sure that Dieda gives a prescription for certain behavior that is attractive to women, for if a man did that, he would by definition become placating. What I got from Dieda is the man should do what he honestly wants to do with little concern for what the woman likes, but by doing that, he makes himself into a secure male that is then attractive to a particular type of woman. If another woman is not attracted to this version of a man, then so what? She can find someone she likes, but the man needs to be himself and wait for the right woman to follow him.
Trying to put forth certain behavior that is "attractive" to a woman puts the man in the trap of trying to gain approval. The Nice Guy book talks specifically about this and warns of that trap. The book also postulates that this comes about from the absence of father roles and the expectations of the feminist movement to "shape" men in the feminine ideal, and how that "ideal" ends up not being attractive to those women who tried to create it in the first place.
So if there is one particular behavior that men should follow to become attractive to women, I say it is not give a rat's ass about whether you (the man) are attractive to women. That will attract the most women.
