Culture War Roundup for the week of May 20, 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.

No my opinion is not, I think 70 is close to phenotypic average SSA IQ and I consider that African Americans have somewhat similar genotypic IQ to Ivorians because most of their origin is from West Africa (maybe 5 points higher due to White admixture). If you don't like Flynn estimates, get better ones but do not shift into discussion how many degrees Nigerian Americans have (a highly selected group benefiting from race-based affirmative action).

Can you provide a source? Gottfredson puts the black-American IQ average between 85 and 90. Flynn's work is based off meta IQ analysis of IQ testing data largely from before 2000s. I have provided evidence that between then and now that in the Ivory Coast the amount of education has increased. So again, I have reasons to believe that the average IQ would have risen between when the IQ tests had their data gathered to today.

If you're not pulling from Flynn who's the most prominent source behind the 70 IQ estimate for people of Africa then where are you getting your value from? You're the one that needs to provide a source, not me. I've provided numerous sources throughout this discussion to ground this discussion and you've yet to provide anything. This 70 IQ value for people in the Ivory Coast we've been discussing stems from 2rafa's comment several posts up and they point to Flynn as the source so that's the basis for this discussion. If you're using a completely different source to base your beliefs then we can't have a discussion properly. I've made pretty clear where my ideas come from to give you the opportunity to check and you haven't done the same level of effort for me so I'm not going to just take your word for it.

If so (I am not saying it isn't), then you should drop "70 iq people are unemployable" altogether.

Perhaps you have a point here and I should be more clear with my words. - People whose genetic potential caps around 70 IQ and are raised in a Western nation are not mostly employable in Western countries where most jobs are service and intellectual-based. The job-IQ research I'm aware of is done in the US so if you limit the area to just the US you can ignore a lot of other factors that have to be taking into consideration if you try to extrapolate elsewhere. I'm not going to drop the idea altogether. I do get in the habit for talking from a US-centric perspective to thank you for helping me remember to be more specific with my words.

Many people say this, but nearly all twins studies find impact of shared environment on adults low, less than 10%. Research of education>IQ is not stigmatized. Why didn't they come with some impressive results?

And those twins both typically both graduate from high school and still get an adequate amount of nutrition. Just gonna quote Scott yet again:

We know deep biological things matter because it's genetic and correlated with brain size, we know motivation matters because stimulants can raise IQ probably by making people try harder on the test, we know abstract thinking ability matters because of Flynn effect and because people from populations where they've never been exposed to this kind of thing do much worse on tests than is plausible from biological differences alone, and test-taking skills are just a good bet.

Most likely the larger effect sizes are going from almost no education (thus almost no familiarity with abstract thinking) to some education (and some familiarity), and the smaller effect sizes are going from 10 years to 11 years of education or whatever. I wouldn't expect extra education to be very valuable to people already very familiar with abstract thinking, though I'm not sure where to draw those lines.

The difference in an environment where twins grow up in the most extreme examples (upper class America vs lower class America), that gap is smaller compared to the average child in the US and the average child in the Ivory Coast in the 2000s. Both twins still get the benefit of education, which includes learning about abstract thinking. Show me a statistically significant twins study where the twins grow up in two completely different countries with completely different standards of education, or where one gets an education and the other doesnt and yet they end up with similar enough IQ and I might think you have a better point here.

Why these are exceptions? They are just conditions with larger effects, there are many lesser conditions. If some condition drives phenotypic ability to perform well on IQ tests, why wouldn't it be drive their phenotypic ability to perform well on a job?

You know what, I think I misunderstood your point earlier and thought you were saying something else. Upon a reread on your previous posts, I think I see your point and have to agree. I believe my revised statement above should account for this properly now.

It looks to me, that I completely agreed with your point that "70 iq Ivorians not same as 70 iq Americans" and yet that you're thinking I am disagreeing and you do not like that I wrote something unflattering for SSA.

Well, my impression was you didn't agree because every time I point out the reasons why they aren't equal, you swoop in to challenge the reasoning and then you didn't explicitly say anything about your thoughts on that until your most recent response. Thank you for clarifying. I think your clarification with "genotypic IQ" and "phenotypic IQ" is actually a very good distinction because when people typically discuss IQ they don't make this distinction, and then racists will take the existing research to justify their beliefs framing it as purely "genotypic IQ" and all this does it prevent further research into IQ which is a net negative for the world since now it's controversial to do research into IQ.
