Rob,
Thanks for this clarification and acknowledgement of what happened with the podcast. Hope you're doing better since your last post.
One question on how I should be interpreting the statements describing your views:
So it seems worth clarifying what I actually do think. In brief, I entirely agree with Matt Yglesias that:
- Returns to additional money are certainly not linear at large scales, which counsels in favour of risk aversion.
- Returns become sublinear more quickly when you're working on more niche cause areas like longtermism, relative to larger cause areas such as global poverty alleviation.
- This sublinearity becomes especially pronounced when you're considering giving on the scale of billions rather than millions of dollars.
- There are other major practical considerations that point in favour of risk-aversion as well.

While in the hypothetical your downside is meant to be capped at zero, in reality, 'swinging for the fences' with all your existing funds can mean going far below zero in impact.
The fact that many risky actions can result in an outcome far worse than what would have happened if you simply did nothing, is a reason for much additional caution, one that we wrote about in a 2018 piece titled 'Ways people trying to do good accidentally make things worse, and how to avoid them'.

So between $1 billion with certainty versus a 10% chance of $15 billion, one could make a theoretical case for either option — but if it were me I would personally lean towards taking the $1 billion with certainty.

I regret having swept those and other complications under the rug for the sake of simplicity in a way that may well have confused some listeners to the show and seemed like an endorsement of an approach that is risk-neutral with respect to dollar returns, which would in fact be severely misguided.
Just wanted to clarify whether I'm meant to be interpreting these as "these are my views and they were my views at the time of the SBF podcast", or "In hindsight, I agree with these views now, but didn't hold this view at the time", or "I think I always believed this, but just didn't really think about this when we published the podcast", or something else?
The reason I ask is because the post makes it sound like the first interpretation, but if these were your views and always have been, to the point where you are saying an approach that is risk-neutral with respect to dollar returns would be "severely misguided", it seems difficult to reconcile that with the justification of publishing the relevant quote[1] as "for the sake of simplicity".
If you are happy to publish things like "you should just go with whatever has the highest expected value", "this is the totally rational approach" for the sake of simplicity when you actually don't endorse the claim (or even consider it severely misguided), what does that mean about other content on 80,000 hours? What else has been published for the sake of "simplicity" that you actually don't endorse, or consider severely misguided? I find this option hard to believe because it's not consistent with the publication/editorial standards I expect from 80,000 hours, nor its Director of Research, and it's an update I'm rather hesitant about making.
Sorry if this wasn't worded as politely or kindly as it could have been, and I hope you interpret me seeking clarification here as charitable. I'm aware there may be other possibilities I'm not thinking of, and wanted to ask because I didn't want to jump to any conclusions. I'm hoping this gives you an opportunity to clarify things for me and others who might be similarly confused.
Thanks!
Edit: Added this quote from the podcast, taken from davidc's comment below:
"But when it comes to doing good, you don’t hit declining returns like that at all. Or not really on the scale of the amount of money that any one person can make. So you kind of want to just be risk neutral."
- ^
"If you were offered a 100% chance of $1 million to keep yourself, or a 10% chance of $15 million — it makes total sense to play it safe. You’d be devastated if you lost, and barely happier if you won.
But if you were offered a 100% chance of donating $1 billion, or a 10% chance of donating $15 billion, you should just go with whatever has the highest expected value — that is, probability multiplied by the goodness of the outcome [in this case $1.5 billion] — and so swing for the fences.
This is the totally rational but rarely seen high-risk approach to philanthropy championed by today’s guest, Sam Bankman-Fried. Sam founded the cryptocurrency trading platform FTX, which has grown his wealth from around $1 million to $20,000 million."
Apologies for maybe sounding harsh: but I think this is plausibly quite wrong and nonsubstantive. I am also somewhat upset that such an important topic is explored in a context where substantial personal incentives are involved.
One reason is that the post that gives justice to the topic should explore possible return curves, and this post doesn't even contextualize betting with how much money EA had at the time (~$60B)/has now(~$20B) until the middle of the post where it mentions it in passing: "so effectively increase the resources going towards them by more than 2-fold, and perhaps as much as 5-fold." Arguing that some degree of risk aversion is, indeed, implied by diminishing returns is trivial and has little implications on practicalities.
I wish I had time to write about why I think altruistic actors probably should take a 10% chance of 15B vs. a 100% chance of 1B. Reverse being true would imply a very roughly ≥3x drop in marginal cost-effectiveness upon adding 15B of funding. But I basically think there would be ways to spend money scalably and at current "last dollar" margins.
In GH, this sorta follows from how OP's bar didn't change that drastically in response to a substantial change to OP funds (short of $15B, but still), and I think OP's GH last dollar cost-effectiveness changed even less.
In longtermism, it's more difficult to argue. But a bunch of grants that pass the current bar are "meh," and I think we can probably have some large investments that are better than the current ones in the future. If we had much more money in longtermism, buying a big stake in ~TSMC might be a good thing to do (and it preserves option value, among other things). And it's not unimaginable that labs like Anthropic might want to spend $10Bs in the next decade(s) to match the potential AI R&D expenses of other corporate actors (I wouldn't say it's clearly good, but having the option to do so seems beneficial).
I don't think the analysis above is conclusive or anything. I just want to illustrate what I see as a big methodological flaw of the post (not looking at actual returns curves when talking about diminishing returns) and make a somewhat grounded in reality case for taking substantial bets with positive EV.
Hi Misha — with this post I was simply trying to clarify that I understood and agreed with critics on the basic considerations here, in the face of some understandable confusion about my views (and those of 80,000 Hours).
So saying novel things to avoid being 'nonsubstantial' was not the goal.
As for the conclusion being "plausibly quite wrong" — I agree that a plausible case can be made for both the certain $1 billion or the uncertain $15 billion, depending on your empirical beliefs. I don't consider the issue settled, the points you're making are interesting, and I'd be keen to read more if you felt like writing them up in more detail.[1]
The question is sufficiently complicated that it would require concentrated analysis by multiple people over an extended period to do it full justice, which I'm not in a position to do.
That work is most naturally done by philanthropic program managers for major donors rather than 80,000 Hours.
I considered adding in some extra math regarding log returns and what that would imply in different scenarios, but opted not to because i) it would take too long to polish, ii) it would probably confuse some readers, iii) it could lead to too much weight being given to a highly simplified model that deviates from reality in important ways. So I just kept it simple.
I'd just note that maintaining a controlling stake in TSMC would tie up >$200 billion. IIRC that's on the order of 100x as much as has been spent on targeted AI alignment work so far. For that to be roughly as cost-effective as present marginal spending on AI or other existential risks, it would have to be very valuable indeed (or you'd have to think current marginal spending was of very poor value). ↩︎
