I don't agree that all these are examples where ethics let slip in a way "that wouldn't be acceptable for academics". Would love to chat in longer former about all this, best off social media :)

FWIW, I am deeply sympathetic to the thesis of the paper—for over a decade I have encouraged students interested in industry research to read Milosz's The Captive Mind in preparation. So I want to help you strengthen the work by encouraging precise arguments.

Huszár et al. wasn't an experiment, it was observational. And the UCSD and Cornell studies both went before IRB. So the journals didn't waive anything, as far as I know. I feel like precision here is quite important, because the history of these studies is full of muddled details.

Thanks, it just didn't seem like any of the three I knew the details of were "examples" of the previous sentence (journals waiving IRB).

Am confused…
- Bond et al [33] was approved by UCSD IRB.
- Thomas & Wahedi [39] both authors had only Meta affils; no university IRB had jurisdiction.
- Huszar et al [75] dunno, cc @inference.vc.
- Kramer at al [82] was exempted; much has been written about this case. See the PNAS ed statement.
