> Conservatives have been consistently in the lead, and there are studies showing how much more prone to believing misinformation they are.
No, that's misleading. Conservatives have also been consistently in the lead on "authoritarianism" to the point that it was considered a purely conservative phenomenon, until someone actually thought to ask questions like "what would left wing authoritarianism look like?" and suddenly they found it everywhere.
You seem not to realize how unreliable the data is on these questions. Not only is the replication rate of psychology and sociology ~35%, but the demographics of those fields yields a clear bias on exactly these questions. You simply cannot draw such sweeping conclusions from the unreliable data we have.
When conspiracy and biased thinking are tested directly, as with the study I linked, there is no difference in how the biases impact their thinking. Both sides are extra harsh on their enemies, are overly forgiving of their allies, etc. Confirmation bias and motivated reasoning all around.
> There's at least reasoned arguments for that.
Do you think that there were reasoned arguments for Trump having won in 2020?
> That isn't the same thing as rejecting useing masks during a pandemic.
They could cite reasons for that too, you just don't believe they are valid reasons. It's the same confirmation bias in all cases though.
