My impressions: I was very struck by how intellectually incurious and closed-minded Alice Crary was about EA (thought this wasn't surprising given her written work on the topic). She would respond to Peter's points by saying things like, "That all sounds very reasonable, so you just must not really be an EA, as I use the term." I had the strong impression she'd never actually spoken to an EA before.

Her overarching framing took the form of a dilemma: either EA is incapable of considering any evidence beyond RCTs (this seemed to be her core definition of EA), or else there is nothing distinctive about EA. Her underlying reasoning, as emerged at a few points, was that EA doesn't tend to fund the (self-evidently good) social justice advocacy of her political allies. The only possible explanation is that EA is blinded by an RCT-obsessed methodology. (Extrapolating a bit from her written work: Demands for evidence constitute moral corruption because proper moral sensitivity lets you just see that her friends' work ought to be funded.) EA is grievously harmful (again, by definition), because it shifts attention and resources (incl. the moral passions of the smartest college students) away from social justice activists. As such, it ought to be "abolished".

In my question, I tried to press her on whether she saw any "moral risks" to her opposition to EA. (In particular, since less effectiveness-focus would predictably lead to fewer donations to anti-malarial charities, is she at all concerned that her advocacy could result in more children dying of malaria.) She offered a politician-style non-response, that in no way acknowledged that trade-offs are real, or that there could be any possible downsides to abolishing EA. I was not impressed.

Fortunately, Peter did a great job of pushing back against all this, clarifying that:

• RCTs are great, but obviously not the only kind of evidence. EA is about evidence, not just about RCTs. (Some projects can be quite speculative. Peter stressed that expected value reasoning can be quite open to "moonshots".) Still, it is important to do followups and be guided by evidence of some sort because otherwise you risk overinvesting in debacles like Playpumps.
• If there's evidence that justice-oriented groups are doing work that really does a lot of good, then he'd expect EA orgs to be open to assessing and funding that.
• Before GiveWell came along, charities weren't really evaluated for effectiveness. Charity Navigator used financial metrics like overhead ratios which are entirely disconnected from what actual impact the charity's programs are having. Insofar as others are now starting to follow GiveWell's lead and consider effectiveness, EA deserves credit for that.

Previous forum discussion of Alice's book: Book Post: The Good It Promises, the Harm It Does: Critical Essays on Effective Altruism and Review of The Good It Promises, the Harm It Does

fyi, the recording is now available, and (upon reviewing it) I've expanded upon my other comments in a new post at Good Thoughts. (I'd be curious to hear from anyone who has a strikingly different impression of the debate than I had.)

Keen to listen to/watch this if it's released. Thanks for posting it
