When reading AI reasoning text (aka CoT), we (humans) form a narrative about the underlying computation process, which we take as a transparent explanation of model behavior. But what if our narratives are wrong? We measure that and find it usually is.

Fundamentally: the fact that LLMs' output is linguistic has a MASSIVE attention capture over social scientists in particular.
We need to keep our wits about us when we use these models and avoid anthropomorphizing them purely because of formal similarities in language.

A recently published meta-analysis in Nature Human Behaviour "found evidence supporting the efficacy of social comparison as a behaviour change technique in shaping behaviour in the desired direction".
I was curious, so I re-analyzed the manuscript, but the funnel plots below say it all.
