Introducing Nature Instant!

We've automated rejection so you can get disappointed faster. Because why wait 6 months for reviewer 2 when you can get roasted by an #AI in seconds?

Here is how it works.

Most of the power authoritarians have is freely given. We should not comply with them in advance.

Trump is far weaker than he looks. So is the GOP. We should draw them out, drain them at every opportunity, and fight for people’s wellbeing at every turn.

We have been sent here to fight for people.

Here is my commentary on @ruthrosenholtz.bsky.social's BBS paper. I point out deep parallels between topics in 2D and 3D human vision that are usually studied separately: summary statistics and attention in 2D, and 3D vision. This suggests studying them together. psyarxiv.com/dz3rx_v2

An array of 9 purple discs on a blue background. Figure from Hinnerk Schulz-Hildebrandt.

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.

The effect presumably comes from the absence of S-cones in the fovea.

Ten principles for reliable, efficient, and adaptable coding in psychology and cognitive neuroscience - Communications Psychology Programming is essential for modern research in neuroscience and psychology, but it can quickly become a source of frustration and error. This Primer introduces ten practical principles guiding researchers toward writing clear, adaptable, and easily shareable code, ultimately supporting reproducible science.

If you're paid to collect the data (e.g. as an RA) and you *also* sign on to be (partly) responsible for the manuscript content and its veracity, then authorship may be warranted. More so if you also made any kind of design or analysis contribution.

Should an undergraduate RA be accountable for inaccuracies? imo: if they're not an author, then absolutely not. (see e.g. Gino case -- the "it was the RA" defence). In other words:

Thanks for your thoughts here Alex. I think detailed contribution statements are great and should be mandatory. For me, one thing that differentiates contributorship from authorship is a certain level of responsibility for the content of the manuscript...
