Culture War Roundup for the week of January 19, 2026

This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.

Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.

We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:

  • Shaming.

  • Attempting to 'build consensus' or enforce ideological conformity.

  • Making sweeping generalizations to vilify a group you dislike.

  • Recruiting for a cause.

  • Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.

In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:

  • Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.

  • Be as precise and charitable as you can. Don't paraphrase unflatteringly.

  • Don't imply that someone said something they did not say, even if you think it follows from what they said.

  • Write like everyone is reading and you want them to be included in the discussion.

On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

With an arbitrarily large amount of intelligence deployed to this end then unless there is something spooky going on in the human brain then we should expect rapid and recursive improvement.

...Or unless intelligence suffers from diminishing returns, which actually seems fairly likely.

Where do these diminishing returns kick in? Just within the human form factor we support intelligences between your average fool and real geniuses. It seems awfully unlikely that the returns diminish sharply at the top end of the curve built by natural selection under many constraints. Or maybe you mean to application of intelligence, in which case I'd say just within our current constraints it has given us the nuclear bomb, it can manufacture pandemics, it can penetrate and shut down important technical infrastructure. If there are some diminishing returns to its application how confident are you that the wonders between where we are now and where it diminishes are lesser to normal distributional inequality that we've dealt with for thousands of years?

Where do these diminishing returns kick in?

I'm not sure, but anecdotally I have found that the tail ends of the IQ bell-curve tend to manifest themselves in broadly similar ways. High levels of neuroticism, short time preferences, lack of ability to self-regulate or exercise agency, a propensity for addictive and co-dependent behavior, and difficulty with things like object permanence and constructing functional theories of mind.

Where do these diminishing returns kick in?

Within the human scale, at the point where Von Neumann was a functionary, where neither New Soviet Man nor the Thousand Year Reich arrived, where Technocracy is a bad joke, and where Sherlock Holmes has never existed, even in the aggregate.

Or maybe you mean to application of intelligence, in which case I'd say just within our current constraints it has given us the nuclear bomb, it can manufacture pandemics, it can penetrate and shut down important technical infrastructure.

We can do all those things. Can it generate airborne nano factories whose product causes all humans to drop dead within the same second? I'm skeptical.

Did a notably finite number of very smart people produce nuclear bombs yes or no? Can a notably finite number of very smart people almost certainly produce a super pandemic yes or no? And these are the absolutely mundane appliations of intelligence.

It seems to me that there is a long tradition of smart people coming together an inventing new and not distantly in the past foreseen weapons and technologies. The very nature of these advancements not being seen far before they came about makes conjuring up specific predictions impossible. You can always call anything specific science fiction, but nuclear was science fiction at one point. And there is of course just the more mundane issue of a sufficiently advanced AI that is merely willing to give cranks the already known ability to manufacture super weapons could be existential.

Does it? The human brain is only about three times larger than the chimpanzee brain. But that 3x difference enabled us to take over the world. Or, as Scott put it:

If you were to invent a sort of objective zoological IQ based on amount of evolutionary work required to reach a certain level, complexity of brain structures, etc, you might put nematodes at 1, cows at 90, chimps at 99, homo erectus at 99.9, and modern humans at 100. The difference between 99.9 and 100 is the difference between "frequently eaten by lions" and "has to pass anti-poaching laws to prevent all lions from being wiped out".

I've got to say, sometimes it is pretty funny being on a board where two of the abiding topics of concern are, distilled down a bit, "high IQ people being wiped out by lower-IQ people" and "high IQ AI wiping out lower-IQ people."

Anyway, there's obviously not a direct correlation between intelligence and existential risk. Creatures with an IQ of 0 on a scale of 1 - 100 for intelligence are in a far less precarious position, existentially speaking, than creatures with an IQ of 100 (us). Intelligence is only an imperfect proxy measurement for power and power is what generates existential risk.

It seems to me that it does, yes. If your intelligence scales a hundred-fold, but the complexity of the thing you want to do scales a billion-fold, you have lost progress, not gained it. The AI risk model is that intelligence scales faster than complexity and that hard limits don't exist; it's not actually clear that this is the case, and the general stagnation of scientific progress gives some evidence that the opposite is the case. It seems entirely possible to me that even a superintelligent AI runs into hard limits before it begins devouring the stars.

Now on the one hand, this doesn't seem like something I'd want to gamble on. On the other hand, it's obviously not my choice whether we gamble on it or not; AI safety has pretty clearly failed by its own standards, there is no particular reason to believe that "safe" AI is a thing that can even potentially exist, and we are going to shoot for AGI anyway. What will happen will happen. The question is, how should AI doomsday worries effect my own decisions? And the answer, it seems to me, is that I should proceed from the assumption that AI doomsday won't happen, because that's the branch where my decisions matter to any significant degree. I can solve neither AI doomsday nor metastable vacuum decay. Better to worry about the problems I can solve.
