ArXiV has a new LLM policy (Screenshots with alt text so you don’t have to click through to the other place and see all the stupid responses)
Attention @arxiv authors: Our Code of Conduct states that by signing your name as an author of a paper, each author takes full responsibility for all its contents, irrespective of how the contents were generated. 1/If generative AI tools generate inappropriate language, plagiarized content, biased content, errors, mistakes, incorrect references, or misleading content, and that output is included in scientific works, it is the responsibility of the author(s). 2/

We have recently clarified our penalties for this. If a submission contains incontrovertible evidence that the authors did not check the results of LLM generation, this means we can't trust anything in the paper. 3/The penalty is a 1-year ban from arXiv followed by the requirement that subsequent arXiv submissions must first be accepted at a reputable peer-reviewed venue. 4/

Examples of incontrovertible evidence: hallucinated references, meta-comments from the LLM ("here is a 200 word summary; would you like me to make any changes?"; "the data in this table is illustrative, fill it in with the real numbers from your experiments") end/

Here’s a thought that might make you tilt your head in curiosity: With every movement of your eyes, head, or body, the visual input to your eyes shifts! Nevertheless, it doesn't feel like the world does suddenly tilts sideways whenever you tilt your head. How can this be? TWEEPRINT ALERT! 🚨🧵 1/n

This is going around again! Clearly it's time to resurrect this which I made for twitter back when it was less evil. Types of Psych Papers [Note: it is slightly more cynical (for humour value) than I actually am]
Types of psych paper: 1) my honours student needed a publication; 2) I have this enormous dataset that I don't know what to do with but isn't it cool? 3) people on MTurk can sometimes learn things; 4) children are like weird adults; 5) my model does the same thing as previous models but is Bayesian; 6) people make silly decisions; 7) I found random noise in my data and made up a big theory to address it; 8) my research doesn't need math but if I have equations people will think I'm smart; 9) my model doesn't explain things but has nice fits, see? 10) things get weird as soon as you have people in groups; 11) all of cogsci is like undergrads at my university; 12) humans, what the heck?!?
