Although Machado ultimately said she was dedicating the award to Trump, her acceptance of the prize was an “ultimate sin,” said one of the people. “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,” this person said.

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.

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

Iconic cartoon showing a single driver in a wide car taking up most of the street space. With many people crammed into the bus, bike and pedestrian space left over. Someone later added a voice box with the driver saying “Damn those bike paths and bus lanes taking all the space!”

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 😔

“Deserve” sorry

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.

The Impact of Freedom of Speech on Conspiracy Beliefs Conspiracy beliefs are often portrayed as a threat to democracies. However, less is known about the extent to which the state of democracy may affect conspiracy beliefs. Hence, we investigated the im...

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!!

If the University of Chicago Won’t Defend the Humanities, Who Will? Why it matters that the University of Chicago is pausing admissions to doctoral programs in literature, philosophy, the arts, and languages

“Chicago has long helped to keep alive tiny fields & esoteric areas of humanistic study... Without the univ’s support, & the continued training of grad students who can keep these bodies of kn going, entire spheres of human learning might eventually blink out.” www.theatlantic.com/culture/arch...

Cartoon illustrating, how traffic induces more traffic. “There is too much traffic for Billy to walk to school, so we drive him.”

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.
