Having skin in the game makes one thoughtful. Sometimes it works in debates too. "Let's do A, it's much better design." "Will you do the debugging and support for the feature?" "Ummm, maybe let's rethink this A, I see some flaws in it."
Could be. With no financial reward there's not much incentive to spend energy thinking about things: so answers default to supporting political views. Suddenly there's a financial incentive, and so people take a few more steps in their thought processes. (maybe, idk)
