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 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

“Over the past 20 years, Paris has undergone a major physical transformation, trading automotive arteries for bike lanes, adding green spaces and eliminating 50,000 parking spaces.

Part of the payoff has been invisible — in the air itself.”

Leadership, strategy, real action, common sense. #Paris
Paris said au revoir to cars. Air pollution maps reveal a dramatic change.
Air pollution fell substantially as the city restricted car traffic and made way for parks and bike lanes.

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

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.

What’s in a correlation?
Correlation may not imply causation, but let’s just ignore that for a second. Correlations are standardized effect size metrics and as such have some quirks by design. These are benign enough when you...

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...

Clear advice from @catherinedevries.bsky.social on clear writing.

Who could argue with such solid advice? (he naively asks the internet)
A Rough Guide to Writing Clearly To write clearly is to take your readers seriously. It means refusing the safety of abstraction and meeting the moment with language that informs rather than obscures. In the spirit of Orwell’s rules, here’s a working checklist for writing clearly: Spotlight our core claim: Don’t hide an argument behind abstraction. If we believe something, state it plainly. If we're uncertain, say so. Define our terms: Especially in public writing, don’t assume our readers to share our definition of “liberalism,” “resilience,” or “hegemony.” And let’s be just as clear about what we don’t mean. Be specific: Abstract claims are weaker than grounded ones. If we write that “many scholars argue,” be ready to name or quote them. Trim the fat: Ask: Can this be said more clearly? More simply? Our reader’s time is precious, and we should respect it. Avoid the passive: “The report was released” distances cause and effect. Say who did what: “The agency released the report.” Check our tone: Clarity doesn’t require condescension. Be precise without being pedantic, concise without being abrupt. Above all, write to be understood: Don’t write to be clever, to be admired, but write to connect.

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.
