This seems like an interesting attempt to see how far LLMs can help with social science research. But I am not sure how much progress will come from producing more papers. What we need -I think- is figuring out how to use LLMs to produce better papers.​​​​​​​​​​​​​​​​

These are essential questions to be asking right now. Ignoring the power of these models (which are only getting smarter by the month) is a recipe for professional obsolescence for one's self and their students.

The science ( knowing *which* models to fit, *why*, and what the answer means) still requires expertise. It didn't happen automatically. But the implementation did. What are we actually training our students *for*? And are we teaching the right things? We really need to start answering this. 3/3

New post on Data Colada. I spent a very long time trying to figure out a figure in a methods paper that is not in my area of expertise. It shows extremely *negative* R-squared values from replications of a true effect. The question on my mind was: WHAT?? I learned some stuff. datacolada.org/134
