Conspiracy theorists' insistence that people should "do their own research" doesn't seem to emerge in their actual choices (i.e., they don't robustly seek out first-hand evidence instead of expert opinions). journals.sagepub.com/doi/full/10....
We should no longer trust data collected on MTurk

My guess is that other online data is going to drop in quality due to LLMs. This is going to be an existential crisis for the behavioral sciences.

Affective inertia, the association between affect at two timepoints, was stronger overnight than it was within a given day. So if you woke up on the wrong side of the bed, you likely fell asleep on it too. www.tandfonline.com/doi/full/10....

Oh man. I'm imagining his description of the false sunrise of dragon fire coming from the North and Maeglin's descent into spiteful hate and yeah, you're right, that would be amazing.
