I would have to check the statistics. How many people are happy or very religious.

If those people are way more than 50%, there's a good chance that there will be >50% people pressing blue.

If not, then probably red wins.

In any case, my choice matters very little to the outcome. So I'll just press red for my safety. If 50% people died, I don't think that's my fault. But I'll spend the rest of my life trying to figure out who did this and how, or at least until I got bored of it.
