  - I do have a sense of caution about what is essentially a polytheistic practice; I’m an atheist who’s generally fine with engaging in woo in a spirit of experiment, but I have a vague sense that dealing with gods is probably frowned upon by monotheists for good reason. It might do something to you that you wouldn’t want. In the same way that some people argue IFS can “give” people something more like multiple personalities when it’s healthier to be unified, I wonder if dealing with multiple gods might “break up” your sense that you live in one world/one reality. (A friend of mine used to joke that atheists believe in one god, Athe.)

  - https://openresearchinstitute.org/onboarding/A_B_U.html I like this A/B/U system.
  - When I encounter a claim, I can’t usually easily sort it into “I believe this” or “I don’t believe this”. There are other buckets, like “all I know is this guy said the thing, I cannot or have not compared it to my other beliefs to see what I think of it”. Epistemic systems need an “other” bucket, not “I think it’s true”, “I think it’s false” or even “I am uncertain”, but something like “unprocessed”. Most claims I read are unprocessed! (Certainly most upsetting claims go in the “gee, that would suck, wouldn’t it? i can’t stand to think about it!” bucket.)
    I also like that U stands for “unclear, undefined, unknowable, or untrue”—i.e. anything where I don’t clearly recognize the truth of it. it’s caused a lot of anguish for me over the years when I can’t rule out that a claim might be true. In A/B/U, you don’t actually have to distinguish “true” from “false” every time; you distinguish “clearly true” from “everything that’s not clearly true”. Thinkers who throw up a lot of Us and not a lot of As or Bs (novel or familiar truths) are not necessarily wrong, but you’re not in a position where you should rationally trust them very far. (And, to put this more reassuringly, you are free to not trust them very far, you are not epistemically obliged to treat them as correct or to keep investigating until you can “disprove” their theories.)

- - https://www.hyperdimensional.co/p/aviate-navigate-communicate Dean Ball has good ideas about governance for Mythos-style models that create security vulnerabilities.
  - yes, if we’re going to regulate AI capabilities, the government should pick a rule and stick to it, not permit models from its friends and forbid models from its enemies in the ad-hoc fashion the Trump Admin has been. Also, it probably makes more sense to have independent, government-licensed private organizations do the model evaluations than to do it within tiny CAISI.

  - https://www.bitsaboutmoney.com/archive/nonprofit-indicted-bank-fraud/ damning stuff about the SPLC and associated nonprofits, by Patrick McKenzie at his most acid. yes, it looks like they plainly broke the law by lying to banks about the shell companies used to pay hate group informants. Also, they may well have broken the law in additional ways, by campaigning to get fund transfers to Trump-supporting political donation groups blacklisted. (nonprofits are not allowed to take sides on political campaigns.)
  - In general, I’m sympathetic to private boycotts or corporate policies against speech they consider bigoted or otherwise inappropriate. Free speech and free association should protect private individuals and organizations who object to certain views and choose not to do business with those who express them. And there are views I find objectionable and prefer not to encounter, with different standards for different contexts.
    but the campaigning behavior being described here seems legitimately horrible. this was not an organic expression of public distaste. it was also not a set of independent choices by corporate executives based on their own values. it was a manipulative and gross organized campaign. even where this sort of behavior is legal, it violates some of my strongly held intuitions about “minding one’s own business”. it is really not some activist group’s business to tell corporations who they may and may not platform or allow to access financial services! you can have an opinion, but you can’t presume to give orders when it’s not your company and not your money. and no business should be taking orders from people who, properly, are just bystanders who happen to have opinions; it’s astonishing that they did. Something very screwy went on here, and I think I understand some of the accusations over the past several years better than I used to.

- - https://benjaminrosshoffman.com/telescopes-need-good-lenses/ this amounts to “yes, I think I am a better parent than liberals/progressives.” I am unconvinced.
  - One of his examples is that his kids are in the 99th percentile for height and weight despite not being visibly fat, thus he thinks that other parents are underfeeding their children. This doesn’t make sense. Child obesity is in fact a significant problem; on average, US parents probably feed their kids too many calories, not too few.
    The fact is that—I don’t know why, maybe measurement error at the doctor’s office, which is common—it’s not that unusual for kids to be “outliers” in size. Anecdotally it seems to me like “99th percentile” large or “1st percentile” small kids (who appear neither fat nor scrawny) are a lot more than 2% of the population. the thing is, the official distribution of heights and weights for kids is very narrow, so a “99th percentile” kid is not that enormous, and a 1st percentile kid is not that tiny. Plus, kids’ growth rates change enough over time that they usually grow out of “outlier” status. IMO, Ben’s kids are normal-sized, their “99th percentile” status may very well be random fluctuation unrelated to how he feeds them, and he is really jumping to conclusions from inadequate data to conclude that most of his peers underfeed their kids.
    I’ll grant him that being better at cooking tasty food might make kids less likely to be picky eaters, but there’s a lot of noise in that as well (I’m a pretty good cook and my kids often don’t like what grownups think is delicious). And I also am skeptical that liberals are worse cooks than conservatives on average in the US. (remember, the OP Scott post was about politics!)
    I have less objection to his overall point, which is a critique of altruism itself. Yes, people will never be as careful or as grounded, as effective, in helping others, if they’re motivated primarily by getting good-boy/good-girl points, as if their practical self-interest is entangled.
    I’m not sure that I buy that EA-style or progressive-style altruism is outright bad; for the most part, i think people aren’t harming themselves by doing it, and even if they help suboptimally they may still be helping a little. I see people as mostly putting themselves first, with a little ineffectual flavor text to make them feel good about themselves, and maybe also a little genuine help going to people who need it, and I don’t see a problem with the flavor text or the modest amount of help. I think charity is not obligatory and not the most important part of morality, but it’s probably net good; and I’m not too fussy about whether people rationalize/exaggerate how good they are, if it makes them feel better. (I also think building AI is cool and have no moral objection to it, so I don’t hold EAs blameworthy there either.)
    I don’t like the idea that we evaluate the goodness of “communities” by how “functional” they are, including via measuring fertility—yes, in an evolutionary sense, fertility is “fitness”, but that doesn’t tell me why i should care about it. I don’t want to be Satmar or Amish. If they are “virtuous”, so much the worse for virtue!
  - https://icmi-proceedings.com/ICMI-E-virtue-under-pressure.html Tim Hwang is trying to make AIs with Christian values. this freaks me out, even though i suppose it shouldn’t (Christians are not so overwhelmingly dominant worldwide that we wouldn’t also have secular AIs)

  - https://nymag.com/intelligencer/article/why-citrini-research-sent-an-analyst-to-the-strait-of-hormuz.html I gotta admire a finance firm that sends a researcher to an active war zone to get firsthand data.

- https://www.astralcodexten.com/p/against-the-concept-of-telescopic
- - I basically agree based on personal experience that telescopic altruism is not a thing. Liberals, progressives, and EAs who care about distant strangers don’t especially neglect their own family and friends. It’s just not a pattern I observe at all.
  - It seems like everyone puts themselves and their family/friends first. and to the extent “lefties” even do tend to care more than “righties” about distant strangers, that care doesn’t seem to come out of a fixed budget such that “righties” do nicer things for their family & friends. the “extra caring about strangers” is either virtually free (it affects how you vote, or how you talk, or what you read, or what you work on, and “righties” also vote/talk/read/work, just differently) or it just makes you generically more worried, because you worry about distant people in addition to nearby people.
  - I do think there is a thing where some people put energy into following politics at the expense of their career or their housework, which is a sort of “caring about distant strangers more than matters close to home”, and can be irresponsible… but that seems to exist on both sides of the political spectrum!

Maybe the problem is precisely the Malthusianism and, if i have to pick my flavor, i might pick Jewish Malthusianism as the least-worst option.

- https://paulgraham.com/mean.html obviously everything Paul Graham said during his tenure at YC was more about what he wanted founders to be like than what they necesssarily were like...but i do think i agree, actually, that mean people fail. at least, I agree with the weaker claim that the most overtly nasty people are usually jobless and socially isolated. successful people may be ruthless, but almost all of them have manners.
- https://www.anthropic.com/news/claude-is-a-space-to-think I like that Anthropic is branding itself as the less-skeezy AI. i want to use products that have a “we’re the Good Guys, we keep it classy” brand identity, even if obviously there are some compromises made for the sake of profit. a company culture of “we don’t do that lowest-common-denominator shit, we have Honor” is obviously toothless from an incentive perspective but can in fact hold out for some time and provide a better-quality customer experience.

  - one annoying thing about anti-psychiatry people is that they equivocate between “the person labeled insane is behaving in a valid fashion, and deserves acceptance/respect rather than pathologization” and “the person labeled insane is causing their own problems and ought to stop; they deserve criticism rather than therapeutic treatment”
  - either of these can, imo, sometimes be true, but it’s weird when someone is trying to pose as both the defender of the misunderstood and the teller of hard truths to malingerers.
- https://www.darioamodei.com/essay/the-adolescence-of-technology not a lot of news in here; Dario Amodei lays out “Anthropic-ism”, the summary of their research & policy programs of the past several years.
  - he and Paul Christiano deserve credit as the architects and prophets of the age we’re living in. things did, after all, turn out their way. i was always critical of their theories as basically blurring boundaries between “real intelligence” and the thing LLMs do, but in their defense, that boundary has turned out to be blurrier than I expected.
  - i think i might be at least sympathetic to Anthropic-ism. it turns out that a world with these kinds of gradually-and-quickly-improving AI tools is pretty nifty, and also involves all kinds of novel risks that are short of the “everyone dies instantly” scenario but are still quite worrying. sure, if they had listened to Eliezer they could simply have not chosen to go down this path, and there’s more than a hint of vainglory in the motivations of people who want to build powerful AI, but all in all I’d rather the 2020s had these tools than not. it’s not like the “end of the end of history” wouldn’t have happened anyway, and at least this way we have some powerful opportunities as well as depressing developments.

in reply to: sarahconstantin’s comment on: What comes after Roam’s renaissance?
as of now, i’m using a Claude Code-generated app for the same logging and diary functions as my private Roam. I had no compelling reason to switch to a different app, but a natural-language-queryable, endlessly reconfigurable interface? yes please. it can do everything I wanted out of Roam plus anything else I want!
