I think a very interesting trait of humans is that we can for the most part collaboratively truth-seek on most issues, except those defined as 'politics', where a large proportion of the population, with varying IQs, some extremely intelligent, believe things that are quite obviously wrong to who anyone who has spent any amount of time seeking the truth on those issues without prior bias.

The ability for humans to totally turn off their rationality, to organise the 'facts' as they see them to confirm their biases, is nothing short of incredible. If humans treated everything like politics, we would certainly get nowhere.

I think a community hazard would, unfortunately, be trying to collaboratively truth-seek about political issues on a forum like LessWrong. People would not be able to get over their biases, despite being very open to changing their mind on all other issues.
