I said maybe only because--there's this famous psychological example where people don't want other people to have more than them, even if, hypothetically, giving other people more means they'd get more than they'd normally get. (Sorry if that's not clear; brain not working so well and it's late.) So, like, logically speaking, if nobody else will volunteer (i.e. if there isn't a logical alternative candidate in the mix) you'd be best off volunteering cause 50% is as good as you're gonna get anyway, plus you do this good deed: logically, that should be a no brainer, except for some people, the very fact that others are getting more than you even if you yourself gain and/or don't lose is a problem.

That's about as clear as I'm getting on this tonight! *G*
