Culture War Roundup for the week of October 24, 2022

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.

I just created an account on The Motte to PM someone a question, and afterwards I started browsing through some links and found this post in the vault: Belief Against an Intelligence Gap / Why the Woke Won't Argue: A look at Turkheimer and HBD research.

Now, a year ago or so, I would probably have strongly agreed with this post. But recently, I've come to a totally different conclusion: HBDers tend to totally refuse to engage with basic principles of the debate. I say that as an HBDer who has started interacting with other HBDers, and correcting when they make mistakes. Two core examples I have in mind:

  1. Heritability simply does not mean what a lot of HBDers want it to mean - because of the phenotypic null hypothesis. You often see HBDers declare success when yet another twin study shows that yet another variable is highly heritable, or that there is a genetic correlation between two variables which are usually suggested to be causally linked to each other. In the latter case, I often see HBDers act as if the genetic correlation proves that there is genetic confounding between the two variables, which is a ridiculous suggestion if you think through the actual math. It's perfectly reasonable to say that the debate struggles with progressing because anti-HBDers aren't properly engaging with HBDers, but it would be a lie to also pretend that HBDers aren't also guilty of lack of thought and engagement.

  2. HBDers often signal-boost nonserious or dishonest studies. My go-to example of this is this study on effort and IQ, which claimed to find that effort does not matter for IQ scores. This obviously massively contradicts common sense, and indeed when I took a quick look at the study, its data actually totally supported the notion that effort matters for IQ, and it's merely that the researcher (who is a well-respected leading IQ researcher!) analyzed it wrong (see my analysis in the thread, or perform the analysis for yourself). The researcher still has not changed his mind on the flaws of it, and I regularly see the study pop up on my timeline. If HBDers are going to boost these kinds of studies and ignore critique of them, then why should anyone listen to HBDers?

So, what view would I suggest? A far more symmetric view: Leftist inclined people want to create racial equality of outcomes, and they therefore boost whichever kinds of rationalizations they can come up with for the achievability and justification of such equality. Rightist inclined people want to preserve racial inequality of outcomes, and they therefore boost whichever kinds of rationalizations they can come up with for the unachievability of equality and justification of inequality. There's some honest people on either side who have been swept up in the drama, but in terms of the direction of the energy which drives the whole debate, this is what lies underneath it.

To people arriving late to this discussion, a couple of things might be helpful to know:

  1. When tailcalled is saying "heritability doesn't mean what a lot of HBDers want it to mean", his actual argument isn't presented in his post. You'd need to go track it down through the link he posted of his substack. It basically boils down to a longwinded form of "correlation doesn't necessary imply causation", i.e. if parents and children show significant correlation on a certain measure, that doesn't guarantee it has a genetic outcome. A good example someone posted downthread would be "knowledege of the French language", which is highly correlated between parents and their children, but which obviously isn't genetic.

  2. When tailcalled says "HBDers often signal-boost nonserious or dishonest studies", he's mainly referring to people doing this repeatedly on his Twitter posts". He's not really calling out anyone here, and importantly he's not necessarily saying this is an asymmetric problem with HBDers, just that some HBDers do it, which... well of course they do. There are knuckleheads on both sides.

So in the end, I think tailcalled is making points that are agreeable almost to the point of being anodyne, but he wrote them poorly enough that some people (including me, at least initially) are getting confused. On #1, we really shouldn't be forced to track down the basic gist of an argument on another website before the author starts claiming it's a big reason why the HBD-vs-Environment debate isn't advancing. On #2, I think a lot of people got the sense that tailcalled was an anti-HBD'er, but the opposite seems to be true actually. He seems to mostly just be patrolling the pro-HBD side for bad arguments as a way to advance discussion, not necessarily to dunk on the HBD side as entirely meritless.

It basically boils down to a longwinded form of "correlation doesn't necessary imply causation", i.e. if parents and children show significant correlation on a certain measure, that doesn't guarantee it has a genetic outcome. A good example someone posted downthread would be "knowledege of the French language", which is highly correlated between parents and their children, but which obviously isn't genetic.

I disagree with this presentation of my views. I am admitting that genetics is causally upstream of the heritable variables; the issue is that not every causal link in the chain from genes to the variable are meaningfully biological. I don't think the French example is an example of what I am talking about at all.

He's not really calling out anyone here, and importantly he's not necessarily saying this is an asymmetric problem with HBDers, just that some HBDers do it, which... well of course they do. There are knuckleheads on both sides.

Yes. The thing that triggered it was going through the vault and seeing that a post going "haha, HBDers are so much better than antis" had been declared a "best of".

He seems to mostly just be patrolling the pro-HBD side for bad arguments as a way to advance discussion, not necessarily to dunk on the HBD side as entirely meritless.

Yes, there's a severe need for patrolling for bad arguments IMO. Both sides seem to have turned into echo chambers.
