Initial State:
As alcohol is further consumed, the mind resembles this state:
Now there are a couple of take home messages here:
Firstly, it's important to the recognise the importance of social factors in female decision making and of its relative resistance to alcoholic effects. This would seem to indicate that the weighting is "hard wired" and innate to female nature. Men and women process information differently.
Secondly, under the influence of alcohol the weighting given to primitive processing increases while the weighting given to rational and social processing decreases. The net affect is that a woman is more likely to make decisions based on her feelings rather than on rational calculation. In terms of mating, the man that can elicit a sexual/mating response whilst the woman is in this state is going to get the goods. But since the mating response is contingent on activation of the alpha receptor(and this to a certain degree is hard wired) it follows that alpha traits will elicit this response. Traits which elicit a feeling comfort ( Nice Guy traits) are not going to elicit a sexual response. This is why the Nice Guy gets to take the drunk girl home with a peck on the cheek(no sexual response elicited), whilst the dominant jock gets to engage in unnatural perversions(High sexual response). It's also why the "nice girl" under the influence, is prepared to engage in depraved acts since her brain is totally being driven by "basic instincts", the inhibitory cognitive pathways have been neutralised by alcohol.
Tirdly, the choice of mate that a woman makes whilst inebriated is not the choice that she would make whilst sober, as in sober states rational and social factors influence mate selection. This is why the sober woman frequently regrets the drunken one night stand.
Alcohol is a "sleaze propellant" because it neutralises our higher cognitive functions, letting our 'baser instincts" take control. As more alcohol is consumed we in fact become more like animals; and like the animals, mating preference is genetically geared towards alpha males.
