Here is the "effective payline" for each institute, estimated (by Claude) as the percentile where one can expect 80% probability of funding from a logistic regression fit. The effective payline has gone from a historic ~12% to 6% in 2025.

Ever wondered how the Dalmatian Dog effect works?

The human brain can quickly learn from a single experience and generalize it to related experiences β€” an impressive feat so far not matched by AI.

Our new paper in @natcomms.nature.com reveals how this works.

Congratulations, You've Discovered Fatigue Just when I thought I was out, they pull me back in.

After 20 years as psychology's golden child, ego depletion collapsed. Now it's back...with a catch. The secret? Make people work for 30-40 minutes instead of 5. In other words, we finally discovered fatigue.

New post on the redemption tour.

The OPAM conference is looking for new organizers, and senior grads and postdocs are eligible. Please share and post widely! This was one of the best things I ever did for my career, and as a service, and I cannot recommend it enough. Deadline 3/1/26; questions to me or opam.info@gmail.com.

Are you interested in adding Bayesian analyses to your next project so you can finally start interpreting your null results? Then join us tomorrow where Dr. Johnny van Doorn from @jaspstats.bsky.social will give a workshop how easy Bayesian stats can be using JASP! Sign up below!

Line chart of Google search interest for β€œChristmas gift wife” and β€œChristmas gift husband” from November 18 to December 24. Bold lines show the average pattern across 2020–2024, while lighter shaded lines represent individual years. Shaded areas highlight which term has higher search interest at each point in time. The chart shows that searches for gifts for wives peak later in December than searches for gifts for husbands.

I've used Lavaan almost every (work)day for 15 years, but this open source labour of love has never received proper institutional support.

Neural mechanisms of learned suppression uncovered by probing the hidden attentional priority map Learned suppression of distractor locations in visual search emerges through reactive mechanisms that involve initial spatial selection prior to suppression.

We used a brain "pinging" again and found that distractor suppression is reactive rather than proactive, meaning attention is first drawn to the distractor before being suppressed.

A recent redesign of OSF by @cos.io led to widespread access failures. What began as a few broken download links became for me a total disappearance of eight years of DOI-registered work. What happened, how was it resolved, and what it reveals about trust and infrastructure in open science

Overall, we argue that, just like smartphones and wearables, driving behavior is a rich form of sensing data that can be harnessed to understand and promote health and well-being!

Some driving behaviors are highly specific in their predictions. E.g., longer minutes per trip more strongly predicted physical decline than anything else.
