In “Six Memos for the Next Millenium”, Italo Calvino distilled six literary virtues he felt should endure regardless of how the world changed.

As we enter an age of automated evaluation & production of science, what are the parallel epstemic virtues we should try to preserve? We want your input! 🧵

Bottom line:
The “motherhood penalty” is real, causal, and driven by discrimination, not differences in ability.

As the authors put it:
“Giving evidence of being a mother leads to discrimination against mothers in hiring and pay.”

Ik sta vandaag op de website van Knack met de stelling da we amnestie behoren te verlenen aan alle mensen in irregulier verblijf. Een. draadje met argumenten Sharing is caring enzo.

Veelgestelde vragen over starten met kinderopvang Veelgestelde vragen over starten met kinderopvang.

Noem het hoe je wil, maar uiteraard zorgt een maximale kindratio (en andere verplichtingen www.opgroeien.be/veelgestelde...) voor lager aanbod en hogere prijzen – een prijs die ouders niet willen betalen en dus gedragen wordt door het personeel (lagere lonen).

Living the metascience dream (or nightmare) with AI for science What happens when we go from replication crisis to robustness extremes?

AI makes continuous reproducibility and robustness testing trivial. What happens to science under new levels of scrutiny and stress-testing by default?

Some thoughts on how this could play out, informed by watching open science play out over the last decade.

Economic inequality does not equate to poor well-being or mental health Previous correlations of inequality with mental-health problems might have been affected by publication bias.

Nog eens bevestigd: een meta-analyse (11 mln mensen) vindt geen verband tussen inkomensongelijkheid en welzijn of mentale gezondheid.

Cijfers via Eurostat:
ec.europa.eu/eurostat/dat...

Volgens de WHO is partnergeweld nog een stuk frequenter buiten Europa
www.who.int/news/item/19...

De wereld is een betere plek dan vroeger, maar het is schokkerend hoeveel mensen er nog met (partner)geweld te maken krijgen in hun leven ...

* De cijfers zijn nog wat hoger als we ook bedreigingen meerekenen (17% V en 10% M)
* Cijfers voor NL zijn trouwens heel vergelijkbaar. Die van Finland zijn extreem: 28% en 14% mannen slachtoffer van fysiek of sexueel partnergeweld -- 53% en 45% als we ook psychologisch geweld meenemen 🤯

Ik denk dat we inderdaad onderschatten hoe vaak ook mannen slachtoffer zijn van partnergeweld (doch minder dan vrouwen). Wat cijfers op een rijtje:
* 16% vrouwen en 9% mannen in België geeft aan ooit slachtoffer te zijn geweest van fysiek of sexueel partnergeweld
* 30-32% van psychologisch geweld.

Can't imagine this to be the case in econ (and related fields) ... I guess it also shows how different scientific fields can be.

This reminds me of this cool paper by Calcagno et al. that showed that 75% of all published articles in biology are published in the first journal they are submitted to. I guess biologists are (or at least used to be) quite well calibrated:

Do you think that's a good thing? It's the same here in BE; statisticians teaching stats, but I've always feit that's not a good thing because the stats courses are so disconnected from the rest of the program as a result.

Yeah, I just noticed the author has a whole set of papers on this, and the 95% seemed clickbait [and worked]; sorry! :-)

Most people also, obviously, have no club what's going on outstide their own field.

Some fields are probably worse than others, but I think there are at least 2 things going on:
1. Progress: most research looks bad at some point.
2. Scientists being scientists: seeing things that could be better -> our field sucks [more than yours]

Why 95% of Papers in Top-Tier SCI Journals Are Garbage: A Critical Analysis of Academic Publishing Collapse This paper presents a systematic analysis of why the overwhelming majority of publications in toptier SCI journals constitute low-quality or erroneous research

Haven't read the paper yet, but it seems other people think so too.

What’s a multiverse good for anyway?

Julia M. Rohrer, Jessica Hullman, and  Andrew Gelman

Multiverse analysis has become a fairly popular approach, as indicated by the present special issue on the matter. Here, we take one step back and ask why one would conduct a multiverse analysis in the first place. We discuss various ways in which a multiverse may be employed – as a tool for reflection and critique, as a persuasive tool, as a serious inferential tool – as well as potential problems that arise depending on the specific purpose. For example, it fails as a persuasive tool when researchers disagree about which variations should be included in the analysis, and it fails as a serious inferential tool when the included analyses do not target a coherent estimand. Then, we take yet another step back and ask what the multiverse discourse has been good for and whether any broader lessons can be drawn. Ultimately, we conclude that the multiverse does remain a valuable tool; however, we urge against taking it too seriously.

New preprint! So, what's a multiverse analysis good for anyway?>

Ik weet niet of dat door 'n verschuiving in visie komt dan wel noodgedwongen door veranderde realiteit? Dalende onderwijskwaliteit waardoor zelfs de beste studenten (meer) extra studie nodig hebben om als onderzoeker aan de slag te kunnen + wetenschap die veranderd is (meer vereist vaak).

Ik vermoed niet dat iemand hier verbaast van opkijkt, maar het blijft pijnlijk natuurlijk – opscheppen over je eigen onwetendheid past wel goed in de tijdsgeest.

Ik denk dat @debiehendrik.bsky.social al gewoon hoogleraar is, maar voor alle andere ZAP gaat het door de besparingen (naar alle waarschijnlijkheid) langer duren om promotie te maken en de impact van bijv. 3j later promotie is over de hele loopbaan best wel heel groot.
