We have had nearly 3 million years of natural selection wherein the most worthy males have bred and had offspring. We are a product of those 3 million years. Of course we have the instinct - if we didn't we'd have been weeded out of existence pretty damn quick.

Let me put it this way - have you ever seen a little boy of about 3 interact with people? Do they need tactics and pick-up lines and NLP to go and chat to someone they've just met? Do they bollocks - they just rock up and say "look at my cool train". We could do alot worse than learning from children.
