Culture War Roundup for the week of March 30, 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.

It's the gift that keeps on giving. No, neither phonographs nor guilt nor syphilis. It's the COVID-19 zoonosis/lab-leak debate. When last we left it*, the rationalists and the establishment had concluded to their own satisfaction that the origin was zoonotic, happening at the Wuhan Seafood Market. The dissidents looked at their evidence and arguments and were convinced... that the other side was trying to pull a fast one. And there it stood, with both sides convinced of their own hypothesis but no smoking gun present.

Today... none of that changes. A paper published in 2022 argued that two successful introductions to humans was more likely than one, and this was evidence for the zoonosis hypothesis. Dissident Michael Weissman has now published a paper showing the earlier paper has a fundamental error, and in fact one successful introduction is more likely. Weissman had earlier responded to Scott Alexander's arguments with the same math error, before official publication.

I was never satisfied with the Wilf - Miller debate. I felt that Wilf was out debated.

Specifically Wilf didn't get into the weirdness of the Wuhan lab. It's known that Chinese researchers stole flu virus samples from the lab in Winnipeg and brought them to Wuhan. That's important because it implies that the Wuhan lab had a habit of keeping virus samples around without putting them in the official database.

Perhaps it was just to get ahead in publishing virus research, perhaps it was some CCP bioweapons program, perhaps they were stolen samples from an American bioweapons program. It doesn't really matter.

The debate is important because in the case of a lab leak then we're at a point where it's clear that modifying infectious human viruses has killed far more people than it's saved. It should probably be completely banned for the next 30 years or so.

With 75% probability I believe there are a few humans who with 99% certainty know how the pandemic began. Either because they really do understand the science or were at the lab and know it’s the lab.

I don’t believe the intelligence agencies have any ability of my own to figure out how this caused. I am smart. They are smart. I don’t believe us nor Scott have any real ability at making Bayesian predictions on the science we know. We are basically all playing a game of trying to figure out what expert is truly credible on which peace of evidence is highly predictive.
