New pontification piece with @awestbrook.bsky.social and Jean Daunizeau, just out in TICS:
Why is cognitive effort experienced as costly?
(or why does it hurt to think)

never written a review paper before in my life, that was a new and unusual experience
Why is cognitive effort experienced as costly?
A widespread observation is that people avoid mentally effortful courses of action, and much recent work examining cognitive effort has explained subjective effort evaluation – and, consequently, pref...

Anyone understands why such a big part of internet depends on one single US-based company? That sounds like a terrible security flaw on so many levels (sovereignity, vulnerability, etc.)

R.I.P. US-based research 😅
Just unbelievably cruel and stupid.
“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”

For-profit journals are supposed to improve research quality, yet they're perversely incentivized to churn out whatever they can monetize. This was happening before AI (see Strain: bit.ly/43gJPUM), and AI will make it worse.

It's insane that we volunteer our time to help them do so.

Not super reassuring for young european researchers 😅 thank you Donald
Europe's MSCA postdoctoral fellowships are now attracting many researchers who would have gone to the US. So the payline has dropped below 10% (~1,600 fellowships to 17k applicants). Super tough situation. One more reason to double the next Horizon budget, as proposed by the EU Commission.
Applications for MCSA are up 64%! 50% now come from outside the EU. Trump effect?

The European Research market just got a hell of a lot more crowded.

EU should turn on the tap

Evidence that even when LLMs produce similar results to humans, they “rely on lexical associations and statistical priors rather than contextual reasoning or normative criteria. We term this divergence epistemia: the illusion of knowledge emerging when surface plausibility replaces verification”

Effort research is booming & it’s tough to keep up with how it's defined and measured.

Huge kudos to @dhprlab.bsky.social PhD student @lukas-hack.bsky.social for leading our attempt to create an impartial overview & starter guide. Great effort (pun intended 😉)!

Interested? Check it out ⬇️
Exciting milestone, my first PhD preprint is out! 🎉

Together w/ @israelhalperin.bsky.social & @wanjawolff.bsky.social, we put together A Hitchhiker’s Guide to Effort 🪐

New paper from the lab on the predictive role of prefrontal cortex metabolites in motivated effortful behavior in humans. Congrats to Arthur Barakat and @nclairis.bsky.social who led the work & to all our collaborators!
Arthur's main & final PhD paper is finally out! In it, we show that a few metabolites (mainly glutamate, aspartate and lactate) measured at baseline with 1H-MRS in the dmPFC/dACC allow to predict inter-individual differences in the motivation to engage with cognitively effortful tasks! 1/2

"Springer Nature’s group revenue has risen by 6% to €926m (£800m) in the first half of 2025, while adjusted operating profit (AOP) was up by 10% to €241m (£208m)." they could at least say thanks to all of us researchers who made that waste of public money possible 🥲
