when we look at the outputs, there is not much visible change (nicely captured in 2020 here www.fantasticanachronism.com/p/whats-wron..., but see new doi.org/10.1177/2515... for more optimistic signs), but those who want to do more credible science, can do so much more easily today than 15 years ago

so ppl (e.g., see below) interested in good theory could spot the papers more easily and not waste time with weak-theory ones, obviously! 🫣

At #SIPS2025, @alexh.bsky.social argues that even studies based on strong theories should be preregistered. I couldn’t agree more — in addition, I say let’s give them their own badges so they’re not mixed up with the weak ones 💪
(& because badges make everything better 😉)

not only do I disagree with almost everything in the blogpost, I find the image of science it presents genuinely messed-up... I guess I am team Feynman on this: “Science is the belief in the ignorance of experts.”

... and that is already a toned down version of the abstract 🫢 I fully agree that the statements are weak ("can cause", "correlate", "may be associated") and I am fine with that: consensus on the absence of clear evidence for any strong statements has its value. But I see no bold claims there..?

The key value of this study lies in its carefully worded expert consensus statements. Interestingly, while experts often have strong beliefs, the actual evidence tends to be far less clear-cut: the core content is in Supplement S5, from page 64

so, this is just to make a ton of money by short-selling and then tanking the global economy, right? that is likely the whole plan... it is also incidently the first answer given by chatGPT and we already know they use it for their policy ideas ,)

if you are interested in real vs. hypothetical choices and/or Taking Games (a version of Dictator Game), we have a super brief paper showing that hypothetical decisions are not always more prosocial / ethical than the real ones authors.elsevier.com/a/1k0dEc5GSa... / t.co/cfuUTxJeAl

I am really surprised how all over the place these results are... that is much more variability (considering CIs widths) than I would expect... also, what is going on with Heimovitz & Dweck, 2016?! in any case, amazing class project!

wow, talk about life goals! ... anyway, it is quite noisy around here in the last couple of days and every other post mentions some "starterpacks" and at this point, I am afraid to ask...

what a splendid idea, Springer! imagine that anyone can already read any of my articles, it is called "preprints" and you know what is best about it? it doesn't cost me a penny!

it doesn't look so bad... more high quality studies directly evaluating this would be nice (maybe @briannosek.bsky.social has something underway?), but there is no need to pause reforms such as requiring data and material sharing, conducting power analyses, and preregistering hypotheses and analyses
