Summary: a (rather simple) AI bot can not only successfully evade survey-level protections, it can also mimic personas accurately across questions, parse photos/videos, and infer the researcher’s hypotheses to produce data that confirms them.

Gemini 3 performs quite well on a wide range of benchmarks.

NEW: The Tate brothers, who have been accused of sexual misconduct in three countries, had their devices seized by law enforcement when they arrived in the U.S.

Days later, a White House official told DHS to return them.
The White House Intervened on Behalf of Accused Sex Trafficker Andrew Tate During a Federal Investigation
Federal authorities were chided for seizing electronic devices from Tate and his brother, and told to return them, records and interviews show. Experts said the intervention was highly inappropriate.

please remember that an “asset” that produces no value can rise in price **only if** someone else is willing to pay more for it.

"Using a regression discontinuity in time design, we find that mass shootings mobilize local voters (especially in heavily Democratic areas) but do not shift presidential vote choices."

If women are underrepresented in STEM, it's at least partly because men like this offer mentoring, then embarrass themselves by assuming their mentees must be into them, then decide the best solution is to cut ties, which sends the signal to other faculty that the mentee must not be good enough.
The emails have Summers reporting to Epstein about his attempts to date a Harvard economics student & to hit on her during a seminar she was giving.

I see the point of the commentary but am not so sure about these examples... Isn't the PCA doing what it's supposed to do in these examples? (I often use "finding the most informative perspective to look at a fish" as an intuitive way to understand PCA.)

"The barriers to performing sophisticated cyberattacks have dropped substantially—and we predict that they’ll continue to do so."

I'm a longtime fan of Not Just Bikes, but his 95(!) minute video on John Forester and Vehicular Cycling is truly his magnum opus.

If you are even remotely interested in the history of bicycling in America, it is worth a watch.

Hey 👋🏽 Cville peeps! If you haven't voted yet, be sure to get out on TUESDAY, NOVEMBER 4 to vote. Voting is, admittedly, a rather limited way to build political power, but it's still a really important one.

Here's the sample ballot for Cville. Next up, I'll share who I'm voting for, and why

1. We ( @jbakcoleman.bsky.social, @cailinmeister.bsky.social, @jevinwest.bsky.social, and I) have a new preprint up on the arXiv.

There we explore how social media companies and other online information technology firms are able to manipulate scientific research about the effects of their products.

Federal Judges— or staff, but same-same— used "AI" to summarize & draft rulings, issued them w/o checking the work, leading to basic factual errors, & thus undermining the facticity & validity of the rulings entire.

Gee. Who Could Have Foreseen. *stares directly into the camera like in the office*

Two federal judges admitted in response to an inquiry by U.S. Senate Judiciary Committee Chairman Chuck Grassley that members of their staff used artificial intelligence to help prepare recent court orders that Grassley called "error-ridden."
