I want to be this person at *every* conference. Would be the most (and least) popular person. 🥱🫩
Speeches can not be too long- every year an 8 year girl has the task of shouting ‘Please stop, I’m bored’ until the speaker stops talking.

Cow Tools!

We have lived alongside cows for nearly 10,000 years.
We breed them and exploit them

It is now, only now, that we have discovered THEY CAN USE TOOLS

I have been a part of five psychology/public health departments over the years. I wish I could go back in time and tell myself — when I was really struggling and unhappy and felt like I didn’t belong in the field at all — how different your social experience can be from institution to institution.

So much statistics discourse orbits around Bayes verses frequentist debates, but in practice Bayes verses frequentist is often a false dichotomy. Just as important as the inferential strategy is the underlying model, and how that model is specified. 🧵

Amadeu Antonio wurde 1990 von einem brutalen Neonazimob ermordet während die Polizei zusah. „Die Baseballschlägerjahre sind nie ganz weg gewesen und in vielen Regionen kommen sie auch wieder", erklärt unser Vorstand @timoreinfrank.bsky.social was es braucht, damit sich die Geschichte nie wiederholt.
Amadeu Antonio: Todesopfer der "Baseballschlägerjahre"
Am 24.11.1990 wird Amadeu Antonio in Eberswalde Opfer eines rassistischen Angriffs. Sein Tod erschüttert das Land und zeigt die Gefahr rechter Gewalt.

formalizing this process is fraught. This requires a bottom up cultural change starting with doctoral training. Top down impositions such as citation diversity statements come with a lot of other risks.

It is a common theme in academia to forget that faculty also get paid to do research and write papers. Getting paid doesn't mean no intellectual contribution to a paper, otherwise unpaid interns would be the only authors on papers.
Someone asked us (neuromatch.social/@tenzingCont...): if you are paid to do data collection, are you qualified to be an author?
