The thing is, all those red button pressers can't see that, for all their exact and flawless reasoning, they have a bias towards individuality, which they see as the only possibility, and we blue button pressers perfectly understand the math and yet we have a bias towards others, and would sacrifice more readily at many situations like this one. This sacrifice is what reds see as "dumb", but natural selection has chosen this because it probably works.

Both sides have a mental bias, and just can't see each other's "reasoning" because of it.

We blues think of reds as selfish, because we can't conceive of anyone not thinking of the worst outcome for others, and being empathetic about it, making it one's own. And they see us as "virtue signalling", or getting some external value of some kind (recognition from peers) because they can't think of any other explanation to justify that behavior, when it is just pure bias towards sacrifice. Sacrifice is just that, giving something without asking nothing, which does not make sense for a red. Reds think we are dumb but society needs a little more blues than reds. Otherwise it probably collapses.

I'm such a proud blue. in fact... ;)
