The world has changed.Today we live in cities with huge populations.Today,a man might ask out a different woman every day,and not in ten years exhaust the pool of young women who might say yes.A man can afford to be rejected almost all the time,so long as some women consent.This was not the world our foraging ancestors lived in.Back then,the world was sparsely populated.A man might live in a band of about twenty-five people,of whom perhaps six at most would be women of reproductive age,and most of these would be spoken for.It would be common that the man would only have frequent encounters with one or two potential mates.A wise designer of human instinct would therefore give men a fear of “blowing it” with such rare and precious women.The maxim “There are plenty more fish in the sea” would be even less of a comfort to a man who knows that he might not set eyes on another single woman for months.In short,the cost of putting a woman off with a clumsy approach would have been,in the environment of our ancestors,very high.This would lead to a selective pressure on men to take the task of propositioning very seriously indeed.Making a bad mistake would be almost as deleterious to the potential for reproduction,as forgetting to bring a dagger to a knife fight.
