WH sources say Venezuela's opposition leader committed the "ultimate sin": She accepted the Nobel Peace prize. “If she had turned it down and said, ‘I can’t accept it because it’s Donald Trump’s,’ she’d be the president of Venezuela today,” one said. www.washingtonpost.com/national-sec...

This was not an easy one to write, but here it is! 🎈🤡 Freshly published in Collabra: Psychology: the life and death of one of the coolest findings in my PhD dissertation. 🎈🤡 With the usual – and wonderful – Karen M. Douglas, @paulbertin.bsky.social, and @olivierklein.bsky.social. 1/11

I love when colleagues share amazing stories with me! Thanks @olivierklein.bsky.social They Droned Back - Young journalists expose Russian-linked vessels circling off the Dutch and German coast www.digitaldigging.org/p/they-drone...

New publication led by @kenzonera.bsky.social. A very instructive set of studies if you want to teach about transparency and replication.

This iconic Fabian Todorovic cartoon is still one of the best I’ve seen at illustrating the remarkable amount of space we surrender to cars, leaving little space left for everyone and everything else. The text added later makes the bonus point that many drivers still manage to complain about it.

“The paper warned that, in an extreme scenario, a highly persuasive AI chatbot ‘could benefit unscrupulous actors wishing, for example, to promote radical political or religious ideologies or foment political unrest among geopolitical adversaries.’” (I do not think this is an “extreme scenario”…)

new paper by Sean Westwood: With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research

knowing many directly affected, I personally asked some senior male colleagues to speak out about this during my earlier years as a professor, as i felt too vulnerable due to my stage of career.. it was shocking how much this was 'common knowledge' among women and how few male colleagues knew 😔

New publication. Congrats to the whole team, and especially @paulbertin.bsky.social who led this effort. Thanks also to the editor (Nicolas Sommet) and reviewers, who desserve credit for improving our paper.

Yes the BBC edit was poor journalistic form but the research indeed shows that Trump's speech predicted riots, violence, and weapons use on January 6th.

Journal publishers *are* bundling your papers up in "data licensing agreements" for big tech companies to use for AI model training. Our publisher, T&F, got £75m from Microsoft for that last year alone.

Results so stunningly clear they inspired this classic xkcd (xkcd.com/2400/):

Wow and wow and WE MUST ALL DO THIS!!

This post has not aged badly unfortunately.

As our kids go #BackToSchool, never forget that we ARE the traffic that we’re afraid of. If more kids walked, biked or rode transit to school, it would erase a massive number of car trips each day, and our kids would be safer, healthier and better at school. HT Ian Lockwood. Spread the word.

New blog post! Calculating a correlation is easy enough. But let's say you calculated two of them and they happen to differ. What follows from that? Turns out there are too many moving parts for an easy answer. www.the100.ci/2025/07/28/w...

I'm quoted in this piece. In short: do not use ChatGPT or any generative AI as a “therapist.” It’s not sentient. It doesn’t care. It may even lead people toward harm. And nothing shared is protected by HIPAA or real privacy standards; it's fodder for the machine. www.dazeddigital.com/life-culture...

"De grâce, que la Belgique ne réagisse pas trop tard. En commençant par manifester une indignation commune devant des menaces envers les magistrats, car cette indignation est le premier bouclier pour protéger les défenseurs de l’Etat."

Clear advice from @catherinedevries.bsky.social on clear writing. Who could argue with such solid advice? (he naively asks the internet)

Is there a difference between falsification and refutation? Popper used the former in the book about logic of scientific discovery and the latter in the last (conjecture and refutation). And I never understood the difference.

Very sad to learn that Helen De Cruz, who had been a constant online presence for me on Twitter and then here, passed away. Read her last blog post. A little gem on what we leave to others.

Great post on the many bad effects of measles. That Roald Dahl letter of his daughter's death gets me every time tho 😔

"Simpson's gender-equality paradox" surely deserve some award for best title 👑 The gender-equality paradox seems really central to some narrative people have constructed (and successfully sold). I absolutely wouldn't be surprised if it turned out 100% confounding.> www.pnas.org/doi/10.1073/...

I often see Ioannidis' paper 'Why most published research findings are false' on reading lists. And by all means - I found it educational when I first read it. But you might also want a summary of the criticisms on the paper, and we dive into these in our @nulliusinverba.bsky.social podcast episode.

Entendu à un colloque: selon une enquête faite sur un échantillon français (supposé représentatif), on arrête d’être jeune à 42 ans et on devient âgé à 64 ans…

It can be interesting to read why so many psychological scientists have raised concerns - which twice led to a crisis - about (social) psychology for over half a century. There are important lessons we can learn from our history about why these concerns have not been solved.

Great talk by @rritabajraktari.bsky.social at @bapsciences.bsky.social 2025, with a proud supervisor @olivierklein.bsky.social!
