(I’ve only spent several hours thinking about this, so I’m not confident in what I say below. I think Ole Peters is saying something interesting, although he might not be phrasing things in the best way.)
Time-average wealth maximization and utility=log(wealth) give the same answers for multiplicative dynamics, but for additive dynamics they can prescribe different strategies. For example, consider a game where the player starts out with $30, and a coin is flipped. If heads, the player gains $15, and if tails, the player loses $11. This is an additive process since the winnings are added to the total wealth, rather than calculated as a percentage of the player’s wealth (as in the 1.5x/0.6x game). Time-average wealth maximization asks whether , and takes the bet. The agent with utility=log(wealth) asks whether , and refuses the bet.
What happens when this game is repeatedly played? That depends on what happens when a player reaches negative wealth. If debt is allowed, the time-average wealth maximizer racks up a lot of money in almost all worlds, whereas the utility=log(wealth) agent stays at $30 because it refuses the bet each time. If debt is not allowed, and instead the player “dies” or is refused the game once they hit negative wealth, then with probability at least 1⁄8, the time-average wealth maximizer dies (if it gets tails on the first three tosses), but when it doesn’t manage to die, it still racks up a lot of money.
In a world where this was the “game of life”, the utility=log(wealth) organisms would soon be out-competed by the time-average wealth maximizers that happened to survive the early rounds. So the organisms that tend to evolve in this environment will have utility linear in wealth.
So I understand Ole Peters to be saying that time-average wealth maximization adapts to the game being played, in the sense that organisms which follow its prescriptions will tend to out-compete other kinds of organisms.
There is an old LW thread about this, with lots of discussion and links to similar ideas.
This comment feels relevant here (not sure if it counts as ordinary paranoia or security mindset).
I might be totally mistaken here, but the calculation done by Donald Hobson and Paul seems to assume von Neumann’s genes are sampled randomly from a population with mean IQ 100. But given that von Neumann is Jewish (and possibly came from a family of particularly smart Hungarian Jews; I haven’t looked into this), we should be assuming that the genetic component is sampled from a distribution with higher mean IQ. Using breeder’s equation with a higher family mean IQ gives a more optimistic estimate for the clones’ IQ.
Imagine instead some crank racist psuedoscientist who, in the process of pursuing their blatantly ideologically-motiviated fake “science”, happens to get really interested in the statistics of the normal distribution, and writes a post on your favorite rationality forum about the ratio of areas in the right tails of normal distributions with different means.
Can you say more about why you think La Griffe du Lion is a “crank racist psuedoscientist”? My impression (based on cursory familiarity with the HBD community) is that La Griffe du Lion seems to be respected/recommended by many.
As should be clear, this process can, after a few iterations, produce a situation in which most of those who have engaged with the arguments for a claim beyond some depth believe in it.
This isn’t clear to me, given the model in the post. If a claim is false and there are sufficiently many arguments for the claim, then it seems like everyone eventually ends up rejecting the claim, including those who have engaged most deeply with the arguments. The people who engage deeply “got lucky” by hearing the most persuasive arguments first, but eventually they also hear the weaker arguments and counterarguments to the claim, so they end up at a level of confidence where they don’t feel they should bother investigating further. These people can even have more accurate beliefs than the people who dropped out early in the process, depending on the cutoff that is chosen.
If I didn’t make a calculation error, the nobles in general recommend up to a 100*max(0, 1 - (the factor by which peasants outnumber nobles)/(the factor by which each noble is richer than each peasant))% tax (which is also equivalent to 100*max(0, 2-1/(the fraction of total wealth collectively owned by the nobles))%). With the numbers given in the post, this produces 100*max(0, 1 − 1000/10000)% = 90%. But for example with a billion times as many peasants as nobles, and each noble a billion times richer than each peasant, the nobles collectively recommend no tax. When I query my intuitions though, these two situations don’t feel different. I like the symmetry in “Each noble cares about as much about themselves as they do about all peasants put together”, and I’m wondering if there’s some way to preserve that while making the tax percentage match my intuitions better.
I find it interesting to compare this post to Robin Hanson’s “Who Likes Simple Rules?”. In your post, when people’s interests don’t align, they have to switch to a simple/clear mechanism to demonstrate alignment. In Robin Hanson’s post, people’s interests “secretly align”, and it is the simple/clear mechanism that isn’t aligned, so people switch to subtle/complicated mechanisms to preserve alignment. Overall I feel pretty confused about when I should expect norms/rules to remain complicated or become simpler as groups scale.
I am a little confused about the large group sizes for some of your examples. For example, the vegan one doesn’t seem to depend on a large group size: even among one’s close friends or family, one might not want to bother explaining all the edge cases for when one will eat meat.
I noticed that the parliamentary model of moral uncertainty can be framed as trying to import a “group rationality” mechanism into the “individual rationality” setting, to deal with subagents/subprocesses that appear in the individual setting. But usually when the individual rationality vs group rationality topic is brought up, it is to talk about how group rationality is much harder/less understood than individual rationality (here are two examples of what I mean). I can’t quite explain it, but I find it interesting/counter-intuitive/paradoxical that given this general background, there is a reversal here, where a solution in the group rationality setting is being imported to the individual rationality setting. (I think this might be related to why I’ve never found the parliamentary model quite convincing, but I’m not sure.)
Has anyone thought about this, or more generally about transferring mechanisms between the two settings?
I’m curious how well you are doing in terms of retaining all the math you have learned. Can you still prove all or most of the theorems in the books you worked through, or do all or most of the exercises in them? How much of it still feels fresh in mind vs something much vaguer that you can only recall in broad strokes? Do you have a reviewing system in place, and if so, what does it look like?
Comments like this one and this one come to mind, but I have no idea if those are what you’re thinking of. If you could say more about what you mean by “updating/changing after the week”, what the point he was trying to make was, and more of the context (e.g. was it about academia? or an abstract decision in some problem in decision theory?), then I might be able to locate it.
I had already seen all of those quotes/links, all of the quotes/links that Rob Bensinger posts in the sibling comment, as well as this tweet from Eliezer. I asked my question because those public quotes don’t sound like the private information I referred to in my question, and I wanted insight into the discrepancy.
I have seen/heard from at least two sources something to the effect that MIRI/CFAR leadership (and Anna in particular) has very short AI timelines and high probability of doom (and apparently having high confidence in these beliefs). Here is the only public example that I can recall seeing. (Of the two examples I can specifically recall, this is not the better one, but the other was not posted publicly.) Is there any truth to these claims?
What are your thoughts on Duncan Sabien’s Facebook post which predicts significant differences in CFAR’s direction now that he is no longer working for CFAR?
Back in April, Oliver Habryka wrote:
Anna Salamon has reduced her involvement in the last few years and seems significantly less involved with the broader strategic direction of CFAR (though she is still involved in some of the day-to-day operations, curriculum development, and more recent CFAR programmer workshops). [Note: After talking to Anna about this, I am now less certain of whether this actually applies and am currently confused on this point]
Could someone clarify the situation? (Possible sub-questions: Why did Oliver get this impression? Why was he confused even after talking talking to Anna? To what extent and in what ways has Anna reduced her involvement in CFAR in the last few years? If Anna has reduced her involvement in CFAR, what is she spending her time on instead?)
Michael isn’t banned from LessWrong, but also hasn’t posted here in 5 years
He seems to have a different account with more recent contributions.
I wonder if you saw Oliver’s reply here?
Here are some examples I found of non-Wikipedia-related wikis discouraging the use of external links:
Links to external sites should be used in moderation. To be candidate for linking, an external site should contain information that serves as a reference for the article, is the subject of the article itself, is official in some capacity (for example, run by id Software), or contains additional reading that is not appropriate in the encyclopedic setting of this wiki. We are not a search engine. Extensive lists of links create clutter and are exceedingly difficult to maintain. They may also degrade the search engine ranking of this site.
Elinks should be constrained to one section titled “External links” at the end of a page. Elinks within the main content of a page are discouraged, and should be avoided where possible.
If you want to link to a site outside of Wookieepedia, it should almost always go under an “External links” heading at the end of an article. Avoid using an external link when it’s possible to accomplish the same thing with an internal link to a Wookieepedia article.
Avoid using external links in the body of a page. Pages can include an external links section at the end, pointing to further information outside IMSMA Wiki.
External links should not be used instead of wikilinks unless absolutely necessary.
I’m confused about what it means for a hypothesis to “want” to score better, to change its predictions to get a better score, to print manipulative messages, and so forth. In probability theory each hypothesis is just an event, so is static, cannot perform actions, etc. I’m guessing you have some other formalism in mind but I can’t tell what it is.
