"Do we have free will?"

An article linked from slashdot claims, or seems to claim, that in at least some cases, we have no free will.
Horse manure.
Free will is the ability to chose. Simply having a tendency to do something doesn't mean you had to do it. A child cannot be help responsible because it can't really make a choice - it doesn't have the required mental facilities yet. Neither can someone with an IQ of below 40, or someone insane.
But for all the rest of us, we are what we make of ourselves. So I'm lazy by nature, tough shit. Should society pay me an allowance to sit on my butt all day and play WoW?!
