More detail from the footnote on the posting, for those interested:
Security clearance requirements are most common for executive branch placements, for example those at national security-focused departments and agencies. Permanent residents are able to work in most Congressional offices and think tanks, and may also be eligible for certain executive branch placements.
Thanks! Good catch - looks like that didn't save into the URL.
Thanks! In addition to the books in your authoritarianism reading list, I'd suggest two from this (partly long-term-oriented) course on AI governance:
Sorry for my delay, and thank you for posting this!
I have two main doubts:
This piece focuses on criticizing the credence assumption. You make compelling arguments against it. But I don't care that much for the credence assumption (at least not since some of our earlier conversations)--I'm much more concerned with the claim that our willingness to make bets should follow the laws of probability. In other words, I’m much more concerned with decision making than with the nature of belief. Hopefully this doesn't look too goalpost-shifty, since I've tried to emphasize my concern with decision theory/bets since our first discussions on this topic.
You make a good case that we can just reject the credence assumption, when it comes to beliefs. But I think you'll have a much harder time rejecting an analogous assumption that comes up in the context of bets:
We can have expected value theory without Bayesian epistemology (i.e. we can see maximizing expected value as a feature of good decisions, without being committed to the claim that the probabilistic weights involved are our beliefs. Admittedly, this makes expected value not a great name). So refuting the psychological aspect of Bayesian epistemology doesn't refute expected value theory, which longtermism (as I understand it) does depend on.
2. None of the proposed alternatives to expected value maximization fill its important role: providing a criteria of rightness for decision making under uncertainty.
Maybe I should be more clear about what kind of alternative I'm looking for. Apologies for any past ambiguous/misleading communication from my end about this--my thinking has changed and gotten more precise.
A distinction that seems very useful here is the distinction between criteria of rightness and decision procedures. In short, perhaps as a refresher:
Why are criteria of rightness useful? Because they are grounds from which we can evaluate (criticize!) decision procedures, and thus figure out which decision procedures are useful in what circumstances.
A useful analogy might be to mountain-climbing (not that I know anything about mountains). A good criteria for success might be the altitude you've reached, but that doesn't mean that "seek higher altitudes" is a very useful climbing procedure. Constantly thinking about altitude (I'm guessing) would be distracting at best. Does that mean the climber should forget about altitude? No! Keeping the criteria of altitude in mind--occasionally glancing to the top of the mountain--would be very useful for choosing good climbing tactics, even (especially) if you're not thinking about it all the time.
I'm bringing this up because I think this is one way in which we've been talking past each other:
As far as I can tell, this post proposes alternate epistemologies and decision procedures, but it doesn't propose an alternative criteria of rightness. So the important role of a criteria of rightness remains unfilled, leaving us with no principled grounds from which to criticize decisions made under uncertainty or potential procedures for making such decisions.
Loose end: problems vs paradoxes
Hence, paradoxes lurking outside bayesian epistemology are the reason one can never leave it, but paradoxes lurking inside are exciting research opportunities.
Nice, this one made me laugh
Loose end: paradoxes
Other paradoxes within bayesian epistemology include the Necktie paradox, the St. Petersburg paradox, Newcomb’s paradox, Ellsberg Paradox, Pascal’s Mugging, Bertrand’s paradox, The Mere addition paradox (aka “The Repugnant Conclusion”), The Allais Paradox, The Boy or Girl Paradox, The Paradox Of The Absent Minded Driver (aka the “Sleeping Beauty problem”), and Siegel’s paradox.
I'd argue things aren’t that bad.
Also, to make sure we’re on the same page about this - many of these paradoxes (e.g. the Pasadena game) seem to be paradoxes with how probabilities are used rather than with how they’re assigned. That doesn’t invalidate your point, although maybe it makes the argument as a whole fit together less cleanly (since here you’re criticizing “Bayesian decision making,” if you will, while later you focus on criticizing Bayesian epistemology).
Loose end: supposed alternative decision theories
Despite [expected value theory’s] many imperfections, what explicit alternative is there?Here are some alternatives.
Despite [expected value theory’s] many imperfections, what explicit alternative is there?
Here are some alternatives.
Unless I'm missing something, none of these seem to be alternative decision theories, in the sense discussed above. To elaborate:
A two-valued representation of uncertainty, like the Dempster-Shafer theory, lets one express uncertainty about both A and -A
I have several doubts about this approach:
Alternative logics one might use to construct a belief theory include fuzzy logics, three-valued logic, and quantum logic, although none of these have been developed into full-fledged belief theories.
Fascinating stuff, but many steps away from an alternative approach to decision making.
Making Do Without Expectations: Some people have tried to rehabilitate expected utility theory from the plague of expectation gaps.
You make a compelling case that these won’t help much.
Loose end: tools from critical rationalism
For important decisions, beyond simple ones made while playing games of chance, I use tools I’ve learned from critical rationalism, which are things like talking to people, brainstorming, and getting advice.
+1 for these as really useful things that expected value theory under-emphasizes (which is fine because EV is a general criteria of rightness, not a general decision procedure).
Loose end: authoritarian supercomputers
[...] So the question is: Would you always do what you’re told?
Do you really buy this argument? A pretty similar argument could get people riled up against the vile tyranny of calculators.
Apparent problems with this thought experiment:
Loose end: evolutionary decision making
Yes, it’s completely true that decisions made according to this framework are made up out of thin air (so it is with all theories) - we can view this as roughly analogous to the mutation stage in Darwinian evolution. Then, once generated, we subject the ideas to as much criticism from ourselves and others as possible - we can view this as roughly analogous to the selection stage.
As I’ve tried to argue, my point is that, without EV maximization, we lack plausible grounds for criticizing decisions amidst uncertainty. Criticism of decisions made under uncertainty must logically begin with premises about what kinds of decisions under uncertainty are good ones, and you’ve rejected popular premises of this sort without offering tenable alternatives.
Another opportunity that just came out is the Stanford Existential Risks Initiative's summer research program - people can see info and apply here. This summer, we're collaborating with researchers at FHI, and all are welcome to apply.
Also, here's a reading list on democratic backsliding, recently posted as a comment by Haydn Belfield.
Some additional arguments:
Thanks for this! I especially appreciated the recommendations for doing 2-person reading groups, and for having presentations include criticisms.
On top of your recommendations, here's a few additional ideas that have worked well for reading groups I've participated in/helped organize, in case others find them useful. (Credit to Stanford's The Precipice and AI Safety reading groups for a bunch of these!)
I see, thanks for clarifying these points.
I think this mostly (although not quite 100%) addresses the two concerns that you raise
Could you expand on this? I see how policy makers could realize very long-term value with ~30 yr planning horizons (through continual adaptation), but it's not very clear to me why they would do so, if they're mainly thinking about the long-term interests of future [edit: current] generations. For example, my intuition is that risks of totalitarianism or very long-term investment opportunities can be decently addressed with decades-long time horizons for making plans (for the reasons you give), but will only be prioritized if policy makers use even longer time horizons for evaluating plans. Am I missing something?
I'm also curious:
