Other research has shown that Extraverts do better than introverts in a rapid mating context such as speed dating (Luo & Zhang, 2009; also see : the more shy the man appeared, the less popular the man.The researchers suggest that this may be due to traditional male sex roles, which require men to be assertive and proactive in the mating domain, skills that may not come as easily to shy guys.I've already witnesses women saying one thing and chasing after the complete opposite and it simply goes back to the age old question: "What the hell do women want?
The popularity of the speed-dater was also positively related to the choosiness of that speed-dater, although the correlation was only significant among men (perhaps due to the fact that women on average were choosier than men).
Most dates don't turn into anything, which means that a man who is way too serious (some would say desperate) makes a woman feel like she's crushing his hopes and dreams if she rejects him.
Most people don't want to be put in that situation.
Seeing as I have very little understanding of women (as do the rest of us males), perhaps I'm missing something but it sounds quite counter-intuitive.
The arguments for this seem either forced or just speculation because it seems that men who prefer casual encounters or are willing to engage in such, are less likely to want a long-term commitment.
