Here's a suggestion for a New Year's resolution: If you see influential bad research, say something. One part of the whole replication crisis story is that a lot of psychological researchers privately knew that a lot of stuff was bad, but it wasn't discussed publicly.

It finally happened - I was asked to review a paper that cites Martinovici, A, and B (YYYY). Only that I don't have a paper with A and B. For the love of science - read your own papers before submission and don't copy-paste LLM output without verifying every single comma it generates.

I am not anti LLM across the board. But if your use case starts with the necessary assumption that the model is a vessel of all human knowledge, then you are consulting an oracle not doing scientific research.

I don't care about claims for the link between causal inference knowledge and academic career success, but I sure hope that the arrow from lack of single-minded focus is as causal as it gets. It has to be, right? It's just a tiny arrow, there's nothing in between.

when trump and co say they're seizing control of research because of the reproducibility crisis, it's pretty similar to when they say they're enacting trans bathroom bans and sports bans because of violence and discrimination against women.

I think in part the higher education funding crisis and the LLM-teaching crisis actually strike at the same problem, which is that education doesn't work without a broad, society-wide sense that the *actual content* of education - not the credential - is valuable.

Data Colada has submitted a motion for sanction against Francesca Gino and her former lawyer team. I hope the court rules in their favor. It will be a powerful message that sleuths can expose fake research without fearing legal consequences.

Just because your code executes without error doesn't mean there's no mistake in it. Do yourself a favor and write code thinking that another human will have to read it and understand it. "another human" includes you in X months from now
