Confirmation bias is an incredibly stubborn human trait (and a near universal one at that). The particular issue this post is engaging with is called attitude polarization: two groups of people diverging more and more in their opinions despite being presented with the same evidence.
Why are humans like this? I think it’s a survival trait that people conform to the opinions of their in-group and are reluctant to let go of opinions that are most central to their world-view. They’ve already invested a lot in both their in-group and their world-view, so rejecting all that is more costly to them than rejecting the truth about some particular fact (that they may not even care about that much).
When you consider that beliefs and openly held opinions have different costs and different benefits depending on which group you belong to, it becomes a lot less obvious that abandoning a position is the right move.
