Anyone running HSR experiments and willing to consider including what @srajtmajer.bsky.social and I call a "consent-insert" mini-experiment? Let me us know.

Some details on the consent-insert are on pp 45-49 of Defending Consent in Privacy Law

"American innovation" now refers to making a kind of atrocity cronut by combining insider trading with war crimes.

Some minds are louder than others.
His is quiet on the hill.
The mountain doesn’t know what it took to get here, but I do.
Every run earned twice
once on the inside, once on the snow.

Seven Billion Reasons for Facebook to Abandon its Face Recognition Plans Meta’s analysis that it can avoid scrutiny by releasing a privacy invasive product during a time of political crisis is craven and morally bankrupt. It is also dead wrong.

Meta thinks now is a great time to launch facial recognition surveillance tech in their creepy glasses because EFF will be too distracted by fascism to notice.

We noticed.

Hey, remember that time I said that pointing out that AI is giving bad data to ICE is missing the point because ICE doesn't actually care if the data is good? Check out how right I am.

Nearly a third of social media research has undisclosed ties to industry, preprint claims Industry-linked studies were also more likely to focus on particular topics, suggesting these ties may be skewing the field

One of the issues that has come up again and again in my reporting on misinformation and social media is the massive influence social media companies have on research in the field.

Last night a preprint dropped that tries to get at this with some numbers. My piece in @science.org (and πŸ§ͺ🧡 coming):

If you’re at AAAI next week, check out our work on stereotyping in LLMs.

We find LLMs flatten identities into predictable and racially charged patterns.
