Theory put forward by Anthony Sherratt concerning how/why it's the bastards who end up with women:
Women find confidence attractive. The only problem with this is that quite often the other traits a woman may look for are not present in the most common form of Confi-magnon man: the Bastard. Bastards are very confident particularly in social situations because they have less invested in it. That is, they don't really care. And when you don't care there’s little or no nerves, a nonchalant attitude and sometimes a touch of arrogance. This lack of caring (the very lack of the sensitivity that women also want) is easily disguised when The Charm needs to be turned on: true bastards do this easily. Their philosophy is that women are for just their pleasure and I've even had one offer his "hunting philosophy" that went along the lines of "I'll get/ask for sex and I get it or I don't. 99 rejections are worth 1 acceptance." (paraphrased) In summary they see women as a sex toy or meat and it's their low care factor that gives them their confidence, their strongest weapon.
Now women reading this may be crying out NO, No at this point but the real problem lies in the fact that most females seem unable to distinguish between confident bastard (common) and confident man (rarer and becoming disillusioned). After all bastards camouflage themselves well and have more opportunity to practice the charm (ie lies). But unlike confident man the bastards don't follow through. Occasionally they will for awhile (refer: sex-on-tap) but their selfishness will shine through.
The truly sad thing is that because of the higher profile the bastards enjoy a lot of women will generalise and categorise all men into the bastards genre. This is obviously untrue (and unfair) but the sensitive man is the one who is a little less likely to play the games and may often be rebuffed early. Going off on a tangent now... But most men can distinguish between the sleaze/player/bastard (confidant-eructus) and the dying breed of confidant romantics (confidant-heartbrokus).
Ironic that the shallower (and retrospectively less attractive) man is more attractive in the short-term. Is humanity doomed by our own genes? Or just our emotional desires?
