1/#APB Summer 2025 Spotlight Day 20! Many people misunderstand police use of force - how often it’s used, officer shooting accuracy, & training levels. Research by Ariane-Jade Khanizadeh, Craig Bennell, & Heather McGale tests if public education can fix that. 🧵👇

Tyranny is not born overnight. It’s built one compromise at a time.

Column | Zuckerberg fired the fact-checkers. We tested their replacement. Our tech columnist drafted 65 community notes, Meta’s new crowdsourced system to fight falsehoods. It failed to make a dent.

Meta fired its fact-checkers, citing concerns of liberal bias, and replaced them with a version of X's "Community Notes." How's that going?

Well, my coworker @geoffreyfowler.bsky.social proposed 65 fact-checks debunking false posts... and only 3 got approved. www.washingtonpost.com/technology/2...

"Although participants were made aware that the consensus from scientists is that non-verbal lie detection is futile, the inclusion of balanced comments alongside the data still decreased perceived scientific consensus" (Han, Snook, & Day, 2025)

‘People think you come out … and live happily ever after. If only.’ The reality of life after wrongful conviction ‘Sometimes I sit in the bedroom and I’m crying my eyes out like a child’

In a recent interview with The Conversation, Paddy Hill describes his harrowing experience being wrongfully convicted for the Birmingham pub bombings in 1974. His story underlines how the impact of a wrongful conviction can extend far beyond exoneration.

Who’s afraid of academic freedom? - University Affairs Defenders of democratic debate are rising to meet the challenges of ideological polarization, governmental interference, and underfunding of academic institutions.

Academic freedom: universityaffairs.ca/news/whos-af...

"...we must relentlessly explain how it works & show how it benefits society as a whole"

If there was ever a moment where useful idiots who claim that misinformation isn't a clear concept, harms few, & is not widespread, have to come to terms with how their rhetoric is being co-opted by right-wing climate denial think thanks, this is THAT moment. The tobacco playbook - as predicted.

YouTube video by NPR's Skunk Bear Finding The Speed Of Light With Peeps | SKUNK BEAR

It came up, for highly scientific reasons, during yesterday's Data Science Lunch in my department that one can estimate the speed of light using a microwave oven and marshmallows. I've successfully done this experiment in my own home. Here's a nice video explaining. www.youtube.com/watch?v=HwRE...

This sounds simple, but it gets even better: sampling from two exponential distributions, with parameters λA and λB respectively, and choosing the event that happened first, is mathematically equivalent to sampling just once from an exponential distribution with parameter λ where λ = λA + λB. This means that the wait time sampled from an exponential distribution, τ ~ Exp(λA + λB), will work as the scheduling for the next event, whichever type it turns out to be. And, irrespective of the value of τ that this sampling ‘spat out’, we can trust that the event that occurs at that time is of type A with probability λA/(λA + λB) and an event of type B with the complementary probability λB/(λA + λB). This is an insight that may sound too good to be true (Box 1 lists some counter-intuitive consequences); it is key to making the Gillespie algorithm possible. It also extends to more than two event types. Thus, if a lemming can give birth (event type A), or be eaten by a fox (event type B), or be eaten by a skua (event type C), the computation simply employs and the production of another litter can be added to the lemming's life with probability λA/(λA + λB + λC).

This is a very nice clear explanation of Gillespie algorithm @kokkonut.bsky.social

How to Address Misinformation Without Censorship Too often, we excuse misinformation as a matter of opinion or free speech. And the consequences are dire.

Decades of research suggest that authoritarian leaders and their admirers consistently share one thing in common: they twist the truth!

Our OP-ED in @time.com today about how to fight harmful misinformation! And the need to speak out against it. More speech, not less! 💪
