Since it was relevant in Berlin over the last days, two technical tips for communication without mobile communcations or internet:
1. bitchat operates only using Bluetooth and allows communication with nearby people bitchat.free
2. Get a small LoRa device (~40€) for using Meshcore meshcore.nz

The three "waves" of psychotherapy are often described as historical fact, which is astonishing when you consider that they represent the distorted and sometimes straight up incorrect view of a single individual (Hayes).

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!
Would love to hear expert views on this paper. It appears to show that the operationalization of brain activity the field has relied on for 3 decades—the BOLD response—is not actually a sensible measure of brain activity.

Important new paper on normative bias in research. In a many-analyst design estimates produced by pro- vs anti-immigration teams systematically differ, driven by specification choices. It’s exploratory analysis expanding on a PNAS paper, but findings seem plausible. www.science.org/doi/epdf/10....

Sadly, also what happened to large parts of the former psychology Twitter community.
Practitioners mostly went to Instagram, researchers either here or Linkedin (ugh). Now, Linkedin is where you can find most of them.

People are misunderstanding what happened here. They mostly did not go back to twitter. They went to linkedin or substack or threads nowhere and so interesting technical conversations simply didn't happen that could have.
Lots of people tried to reconstruct the ML/AI/stats community over here. 90% of them left because the random abuse they got for just posting ordinary research results was too much.

Have you checked your university’s contract with qualtrics? I noticed mine allowed qualtrics to use survey responses to train AI.
