I agree from a rational perspective, but unfortunately on top of that I find it personally very emotionally draining to see and engage with.

I'm slowly starting to mute the LLMs-are-better-than-us-at-everything nihilist posters on here, so I can focus on interesting (and yes, reasonable) takes.

Classic example of massive confusion in elites in recent decades. The elites are never in danger of being driven into suicide by "motivated" judicial and prosecution projects. We need to keep remembering him!

These accounts exist aplenty. You could think of the entire Bourbaki project as concerned with understanding at a structural level, not problems. What is the right conceptual framework in which this theorem becomes natural? The emphasis was on definitions and conceptual architecture.

Super helpful, thanks a lot! I was already curious about possible surprises. I had read some EU topic-specific hta guidelines, which seemed reasonable though vague.

Thanks for the suggestion! Basically the latter, but with many others having strong but not mainly (public health, pharmacology, econ) stats background.

Ehm, you're including the important initial case "0 kids were so easy, no idea why people are complaining". I like that initial case. Also applies to many things.

It's a systemic problem in science reporting that these summaries exaggerate the evidence. In the actual candy study, the participants were all students, status was manipulated in the lab by telling some students they were better than others, and "nearly twice" means 1 piece vs 2 pieces.
Piff and his colleagues found that upper-class drivers were more likely to cut other cars off at junctions and ignore pedestrians at crossings. Wealthier people also appeared more willing to lie at work. In one experiment, volunteers were left alone with a jar of sweets ostensibly meant for children. When the researchers returned, upper-class people had snaffled nearly twice as many candies as lower-class people.

Weeeell, Austrian German is also called "German", so this always turns into a circular discussion. And nearly all our dialects (one exception) are Bairisch, so... Even though I am sure you know all that, can't hold back on this one 😅

Editors who at least *might* demand revisions if they saw a piece committing an obvious logical fallacy like affirming the consequent routinely *don't* ask pop psych or business psych contributors to demand revisions for selection on the dependent variable.

That's terrible. Even on social media I wonder whether all these people "editing" their posts (LinkedIn looking at you) have led to an increase in perceived quality. Or perceived and implemented "you really don't respect my time".

This doesn't work for confidence intervals that can be the whole real line. Ratio of Normal means (eg cost-effectiveness) is one genuine case (when both numerator and denominator have uncertain sign) and a trivial case is empty set with prob alpha and whole real line otherwise

I've written a few books and checked all the quotes (deleting some bangers because I doubted their authenticity) and if you're letting fabricated ones slip through then you're cutting corners in an egregious way. It is not the copy-editor's job to check every source, it's yours. Do the damn work

Do you have any good refs re punitive vs motivational? I find that already pretty hard to define, since many students who don't cheat consider "punitive" measures simply leveling measures.

I wasn't talking about interventations, I do see your point. But I cannot disagree with the OP that LLM-Ai seems to amplify a lot of this.

Not sure about this. There is a middle class (in many countries), studying in higher ed not simply to survive. Of course there are socio-econ pressures, but there are also other socio-cultural tendencies that push people into opportunism at all costs.

Fabio E. Tonti @tontief.bsky.social · 24/07/2026
I'd even say *rarely* instead of not always. Also, not only psych and bio, I feel like many engineering disciplines do that too, albeit with a slightly different focus. Classic in engineering: use "Analysis 1" for thinning stud population, more applied parts for "real stuff". Bad bad bad.
