fwiw, really appreciated the dialogue here, we are excited to discuss---both the positives and the critiques. There is so much unknown with these models and their potential to improve our methods for social inquiry, but we won't know whats good---or bad--- until we explore.

@mollycrockett also a great way to quickly explore these models in an interpretable way, although LLMs surely can/will be used to do invalid inference with respect towards humans, it doesn’t have to be. They offer us a tool to better understand ourselves-something we currently aren’t great at!

@nickchk From a frequent viewpoint (the only view to use pvalues), these statements don’t make sense. The pvalue only matters in that it is above or below alpha, which controls the long term error rate (the alpha). One can’t have multiple levels of significance - it simply is or it isn’t!

@eizenb_alon @johnjhorton Yes! The agents in the experiments behave in line w/ theory (as you say), but when asked to make predictions, the LLM appears to largely ignore theory. There’s a dichotomy in its use of knowledge and its behavior, and I bet auction lit is very represented in training corpus!
