They would be... if it wasn't retaliation. But if the something that embarrassed the company or that made employees feel threatened was the very thing that was exposed which is being retaliated for - specifically feeling unsafe in the wake of the Arday fraud exposure - that's textbook retaliation!

It sounds like the people who are firing him were responsible for overseeing the hiring, and were grossly negligent in their jobs in several ways, either in the hiring, or in the pretextual firing that was either retaliation, or on the basis of things explicitly publicly discussed when he was hired!

Did you? He was explicitly told that this was partially because people didn't like what he did in exposing Arday's fraud. And I agree he was an asshole about it. But that's still prima facie evidence that it was, in fact, partly retaliation for what he did!

Oh, I certainly agree he's an ass, and I've know that for a couple years. But that's not the question. The question is whether it's OK for Ghent to fire him base on things they knew when he was hired, as a pretext to engage in retaliation. And it seems like we're talking past one another.

David Manheim @davidmanheim.alter.org.il · 26/08/2026
I strongly agree with @evoroseman.bsky.social's points there - but if this was about a poor hire and bad science, it doesn't agree with the claims in the letter explaining his firing, where they explicitly note that this was largely, in fact, about the Arday incident and the reaction.

I'd love to see arguments about the facts and norms that are relevant here - what I see instead is a bizarre level of deference to those who are alleged to have engaged in retaliation when they say it was for the pretextual reasons which they can't disclose details about.

David Manheim @davidmanheim.alter.org.il · 26/08/2026
Right, and imposing consequences in response to something is also often called retaliation. No one is saying Ghent should renew his contract, they are saying that firing him on pretextual grounds, *even if those would otherwise have been sufficient* is now unacceptable, because it is retaliation.

1. I'm not defending what you're claiming I'm defending. 2. You say it's not in retaliation, but that's not credible given that they effectively said the press and coverage around Arday was what made it a problem. 3. Academics are generally free to do other things and aren't kept on tight leashes.

Also, MacAskill tried to resolve part of this. (He's now the big proponent, and has developed this, but to be fair the idea was not at all novel to him, and was discussed extensively over a decade ago on lesswrong, etc.) www.forethought.org/research/the... bsky.app/profile/zach...

I disagree with total utilitarianism generally, as well as not being utilitarian myself, but my biggest pet peeve in this space is infinite ethics, which is simply not based in reality. (Annoyed enough to write a paper about it: philarchive.org/rec/MANWIT-6)

None of this is an argument that it wasn't retaliation, it's just saying that retaliation is fine. And that's a fine position, but it doesn't match the claim that they "support academic freedom 100 per cent" - saying anti-social ideas are disallowed is almost the opposite! aa.com.tr/en/europe/gh...

1. I think that they will have a hard time justifying that they didn't know those things about him when they hired him. 2. Retaliation is a problem, and the burden of proof is on the University to make the case - and not to say "trust us, it's not retaliation, but we can't tell you more about why."

David Manheim @davidmanheim.alter.org.il · 26/08/2026
The reasoning seems clear; right now, it sounds like you're maintaining that if someone is "improperly" hired, then the company should be allowed to fire them to retaliate for, say, reporting a superior for harassment or lawbreaking, on the basis of the things they knew when hiring the person?
100
David Manheim @davidmanheim.alter.org.il · 26/08/2026
Again, the fact that Cofnas is wrong, and is a bad person, doesn't mean that Ghent is not doing anything wrong by firing him! So whether or not I think that Ghent should have hired him, once they did so, they can't decide to fire him in retaliation for what should be protected conduct.
410
David Manheim @davidmanheim.alter.org.il · 26/08/2026
Yes, I certainly agree that the suggestion in the op-ed not to punish Cofnas because otherwise people will commit suicide out of spite was absolutely vile. And Cofnas is also a gross person. But bad arguments for a claim don't invalidate good ones; none of that changes that this was retaliation.

David Manheim @davidmanheim.alter.org.il · 26/08/2026
I don't think I can be any clearer about my opposition to the anti-intellectualism and sabotage of critical institutions on the right, but they obviously don't have a monopoly on stupid and harmful ways to undermine public trust in academia.

The entire notion of retaliation is that they have a pretext. And in this case, it's a thin one; if this wasn't about Arday and the reaction, why are they citing the disruptions that arose recently and new damage to psychosocial wellbeing as part of the reason, and why are they doing it now?
210
David Manheim @davidmanheim.alter.org.il · 26/08/2026
I agree that they are not saying it's due to the incident, but: 1) it's hard to believe that it's unrelated; they said it's due to controversy, 2) the fact they would fire an academic for doing something outside their job description is fundamentally antithetical to the notion of freedom of inquiry!

I don't understand this debate; Cofnas is a racist, and also, he's being punished for reporting what everyone agrees was clear academic misconduct. The fact that he's a gross person doesn't change the fact that retaliation for reporting misconduct is unacceptable and a horrible precedent, right?

Public opposition to data centers somewhat matches the vibes of the people worried about AI safety, but actually stopping their construction isn't meaningfully helpful for AI safety, it's at best irrelevant.

Working on a post on this. And no, not a generation, but I'd argue loosely that the internet-enabled workers work longer hours and have no real time off, even if broader gains are occurring. (Similar to how factory workers and those injured by pollution were hurt, but broader society gained.)

David Manheim @davidmanheim.alter.org.il · 17/05/2026
Alternatively, of course, there are the even larger changes possible. That is, if AI isn't a normal technology, and strong AGI or ASI is developed, we should be looking at a different class of changes - but that's hardly less concerning!

David Manheim @davidmanheim.alter.org.il · 17/05/2026
Yes, I agree the base-rate prediction implies no permanent underclass, and implies long term benefits - but looking at the details, the immediate impact of each was bad for the majority of people for at least a generation. Assuming AI adoption will buck this trend requires more justification.

David Manheim @davidmanheim.alter.org.il · 17/05/2026
What are some relevant base rates? I'd start with revolutionary technologies; agriculture, industrial revolution, computers, the internet. Each seems to promise paradise, but each led to short term consolidation of power and harm to most people (esp. the non-elite) in civilizations adopting them.

David Manheim @davidmanheim.alter.org.il · 17/05/2026
As a forecaster, strongly disagree with @kulveit.bsky.social on this. 🧵 "Massive change" is pushing narratives over base rates and trends; in the past 20 years, inequality increased in developed countries. Predictions defying trends based on "this changes everything" are a common error.

On the other hand, the idea that this can be solved with a more transparent process involving the regulators and the public is just a way of saying they want the data centers blocked. (Though if they failed to plan for the impacts of the power needs, it would serve the data center builders right...)
