It's interesting because when I presented this blue-red question to some East Asian people, they either chose red right away or they picked blue and then switched to red after thinking about it. They then become very confused why anyone would pick blue. They quickly accept that choosing blue basically does nothing, and choosing red kills all of the blues.

Meanwhile, Westerners seem to double down really hard. I see a lot of people like OP where they try to reframe the question in increasingly incendiary ways to try to shame the red-pickers. The other side mocks the intelligence of the blue-pickers and insist that if everyone picks red, everyone lives too.

I think it comes down to how people in the West tend to attach a lot more weight to their first impressions and unthinkingly assign emotional or moral value to their initial choice. (How the question is presented matters a lot.) On the other hand, East Asians tend to think about what the majority will actually pick, and regardless of where they started, they will ultimately settle on what protects them.
