My paper on concerns about replicability, theorizing, relevance, generalizability, and methodology across 2 crises is now in press at the International Review of Social Psychology. After revisions it was 17500 words, so it is split in 2 parts: osf.io/dtvs7_v2 and osf.io/g6kja_v1
Many Gen AI tools are free now. If you do not train yourself (e.g. you never learn how to program without them) you will be dependent on them. In the future they will increase their prices drastically, and you will have to pay, because you can't do without them anymore.

ourselves a few years before my uni created a central one. Of course, this meant the central ERB was based on the one we had already created, which means it works as we wanted it to work. That in itself is an excellent illustration of my original point.

Indirectly, it is. Because Ethics review exists in the US, an increasing number of publishers started requiring it for publication. Publishers and funders are another external power. Our uni get it had to create one. Interestingly, our department had seen this coming, and we created one >

Actually, empirical research shows not everyone hates them, ours is pretty good (COI as the chair). I just got a proposal auto-approved immediately after submission 3 days ago, little to complain about :)
I am sure we did a better job than the government would have done.

This is actually not true, as psychology has ethical review boards as a consequence of a threat of the US government to intervene, as I discuss here rips-irsp.com/articles/103...

For many social dilemma's in Science (e.g. the slow uptake of diamond open access journals) stronger top down management is necessary. It won't just happen. If scientists will not create this management themselves, someone is going to create it for us.

It was great fun to teach a full day course on interpreting statistics to the Dutch Behavioural Insights Netwerk, a collaboration between all Dutch ministries for the application of behavioural knowledge within the Dutch government. They are doing lots of interesting research!

Work programme 2026-2027: the Netherlands takes the next step towards open science | Open Science NL
With its second work programme, Open Science NL takes another major step towards making open science the norm in the Netherlands. On 14 November, the Steering Board approved the programme for 2026 and 2027. It outlines thirteen funding instruments covering the full spectrum of open science, ranging from citizen science hubs, AI, replication studies, to open science infrastructure.

This is an education problem, not a tool problem; and we don't want people simply moving from thinking p-values are magic to thinking confidence intervals are.

To all educators out there: We are trying to formulate a criterion for our exams that tackles the vagueness of LLM output and punishes it more strictly. If you recognize the issue, has anyone of you come up with a crisp operationalization of such a criterion. Also grateful for other pointers 🙏

I have seen the same people criticize preregistration, based on highly unlikely hypotheses about why they would not be needed, or even counterproductive. Literally *none* of these critics have provided any empirical support for their criticism in the last decade. I wonder why.
