Culture War Roundup for the week of February 19, 2024

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.

Modern humans are a lot alike--at least at the genetic level--compared with other primates. If you compare any two people from far-flung corners of the globe, their genomes will be much more similar than those of any pair of chimpanzees, gorillas, or other apes from different populations. Now, evolutionary geneticists have shown that our ancestors lost much of their genetic diversity in two dramatic bottlenecks that sharply squeezed down the population of modern humans as they moved out of Africa between 60,000 and 50,000 years ago.

See: https://www.science.org/content/article/how-we-lost-our-diversity

Yes, this is true.

Now, why is it enough to matter? If the problem was that the out-of-Africa bottleneck of ~10000 or whatever it was, was too small, is there some higher number at which it would make sense to talk about variation being relevant?

Being much more similar at a genetic level than average does not mean that they are similar along any particular trait, as has been pointed out to you repeatedly, and there is clearly enough variation that we can see some traits vary.

My point isn't to disagree that humans have lower genetic diversity than chimpanzees or whatever (especially if we are excluding the most genetically diverse groups like the pygmies, sticking to the majority of the world's population), that's just true, and you're right on that. But you keep bringing this up as evidence that genes can't matter, for which it is only very weak evidence, not at all a serious consideration.

But you keep bringing this up as evidence that genes can't matter, for which it is only very weak evidence.

I'm bringing it up because genes do matter, but there simply isn't nearly as much diversity within the human population which means the overall effect of genetics cannot be large on a population level. It tempers the overall impact of any kind of diversity, the fact that we humans are so similar. I simply do not believe that HBD as seemingly commonly held in this forum is nearly strong enough as a concept to use it as a battering ram to dismiss or deflect the mainstream or the left wing's position on this matter.

I thought I made the comment clear. You still didn't answer, but just repeated what you were saying.

I'll try again: You keep saying that humans have less genetic diversity, therefore there cannot be any substantial genetic effect. But you have yet to show that that's a valid inference. How do you know that the lesser degree of diversity in comparison to chimpanzees or whatever means they can't vary along relevant traits? Why isn't it the case that we have less, but still quite enough, diversity?

As evidence that there's probably enough, we notice variation attributable to genetics in all sorts of other things.

Relevant traits such as height, weight, intelligence etc? Compare Europe with Japan, they are very similar and yet separated by thousands of kilometers.

I see this HBD talk here constantly, yet it seems everyone assumes that it is true without bringing evidence, where is the proof for such a bold claim?

The HBD discourse is fueled by people freaking out over representation in high-status classes like successful CEOs, scientists and Ivy League applicants. People get into those by being outliers on a standard distribution in talent, and this amplifies small initial population differences. A relatively small difference in mean IQ between populations that looks inconsequential in everyday tasks can still end up making the tail of people capable of becoming theoretical physicists have a 2x overrepresentation of people from the higher mean IQ population.

Europe and Japan do have differences in height, weight, IQ, etc. on average, they just aren't huge ones.

We know that IQ is partially heritable. Doesn't that demonstrate that genes can be relevant?

https://en.wikipedia.org/wiki/Average_human_height_by_country#

Sort by height and notice how many shithole Balkan states are toward the top, and how far down you have to scroll to reach even the most prosperous Asian countries. Your hypothesis, that the human genome doesn't have enough variation to allow for meaningful population differences in genetically complex traits, is trivially falsified by the evidence you claim we're not bringing.

Once again, how do you explain height differences?

How much difference would you accept as reasonable based on genetics? Clearly, one standard deviation is too much. A half maybe?

You’re right about the overall limits of variance we are going to see among human populations.

However.

In the grand scheme of things, 85, 100, and 115 IQs are not a huge amount of variation for our species anymore than 5’5”, 5’10”, and 6’3” heights are.

At some point we will have exhausted plausible environmental explanations for the achievement gap.

In fact, we already have, as evidenced by arguments serving as excuses that it would take centuries to get past the effects of misfortune (an order of magnitude more than what the Supreme Court thought), and that ever-present “systemic racism” is behind any disparity, with no need to show actual evidence of racism.

The tide of the evidence is being pulled in one direction along multiple fronts, and so people want to pretend we have the same understanding of genetics as 50+ years ago when it was less clear and explicit oppression was far worse and more recent.

To my friends, everything; to my enemies, epistemic humility.

The average height of a Chinese man is 170cm and the average height of a European man is 180cm. The difference between the two is only a little above 5% on average with recent males being 175cm which indicates that much of this disparity is not genetic, but environmental. This represents populations that are separated by the largest continent in the world.

How much difference would you accept as reasonable based on genetics? Clearly, one standard deviation is too much. A half maybe?

Honestly, probably less than half a standard deviation but probably not nothing. It's not really that important though, because I believe that there are significant gains that can be had if the environmental influences are taken into consideration and ameliorated.

You've already been linked this list, but perhaps you missed some of the implications. Allow me to expand upon this by pointing out some fun facts.

  • Jamaica ranks three places higher than the United States.

  • Jamaica is also 5cm and like 75 spots on the list ahead of Japan.

  • Japan is essentially tied with Haiti.

  • Literally every single Asian country comes in behind Senegal.

All of which raises a huge problem for your position: Assigning more weight to environmental factors makes the genetic gap larger, not smaller. If the likes of Jamaica and Senegal had access to First World medical care and nutrition the same way Japan and South Korea do, how much taller would the former be then? And more to the point, what would nurture advocates blame the enormous difference on then?

The notion that the human genome doesn't have enough variation for large differences in complex polygenic traits between isolated population groups just doesn't hold water. You can ignore this post if you want, but expect to see it again next time you want to bemoan how HBDers won't dig down into the evidence with you.

Obviously much of the historic difference in height is environmental. Look how fast it changed once nutrition improved all over the world, and the longstanding gap that emerged between North and South Koreans.

But certain parts of Europe average close to 6 ft. It’s not like the Dutch have had some special nutrition better than say us in America.

My favorite part is that now you have to explain how we’re going to catch up to the Ashkenazim and their standard deviation advantage over whites.

Half standard deviation is still a substantial gap, by the way. The shift in direction really affects the tails and it would be noticeable. Asians have to be discriminated against at Harvard for a reason.

Japan is tied with Haiti for height. Environmental effects aren't even pushing in the direction he needs them to.

Now consider the difference between Pygmy populations in Africa and Nordics. There's nothing you can feed the former, barring Human Growth Hormone, that will make them reach similar average heights.

And if your (Questionmark's) point isn't about the African pygmies, because they are among the most genetically diverse groups, consider those who are outside of Africa, who are more closely related—there are several groups with average male height under 5 feet.

(to both of you) I'll note that the question as to how much variation is possible, referring to standard deviation, is rather strange, as the standard deviation depends on the variance. I suppose it's possible if environmental factors play a large enough role?
