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.

Notes -
Ok, you reject that both axes of plot are proxies for intelligence. But that is semantic distinction. Ok, call it "ability to do IQ tests". Do you agree that these plots demonstrate various populations different genetic predisposition to do well on an IQ test?
We cannot have a genetic study with N=100,000 of "Hlynka intelligence" as Hlynka is the only person who can measure it and it takes a lot of time.
Pretty much.
To the degree that IQ is measuring something real, I think that what it is measuring is something along the lines of "Academic Aptitude" or "Proclivity for symbol manipulation", and that this quality is only somewhat correlated with the ability to recognize, retain, and reason from/act upon changing information states.
You're dodging question again.
Again, I am not "dodging" anything, I am questioning the entire framework upon which the question rests.
A plot can be made to demonstrate anything. To demonstrate, if I were showed you a plot showing that the ratio of squantches to dingflarbs amongst the black population is less than one, and appended a bunch of Jewish sounding names to the end so you could tell that it had come from a serious academic source would you agree?
Entire framework? Do you question genotyping methods and usage of GWAS linear regression to study associations between phenotype and genotype?
Well, since I don't produce voluminous posts about how mainstream theories about squantches and dingflarbs inaqueduate, I don't see analogy here.
I could agree or I could say "this is good, but would be nice is these results were reproduced by another authors".
I question the motives of both the researchers researching it and the posters posting it, and wonder if they would have published or be posting if they had gotten a result other than the one they set out to find. I know that post is intended as satire but is it really?
The rest is one of those Giancarlo Esposito memes: You didn't ask what a dingflarb is, we are not the same.

Okay, so do you think that there are racial differences in IQ, but not in ability more broadly?
If so, would that suggest that different groups have different strengths, but the different abilities end up cancelling to come to something roughly even when you try to form some (obviously imperfect) measure of true, generic ability? (Not saying whether I think this is the case, just trying to see what your picture of the world involves, and it seems to me like something like that would have to follow?)
I've been led to believe that IQ is fairly broadly impactful, but I don't currently have data at hand to back me up.
I would say that I am skeptical.
I'm skeptical that whatever it is that IQ tests are testing for correlates directly with "intelligence".
I'm skeptical that "intelligence" correlates directly with individual virtue, honesty, conscientiousness, lack of criminality, leadership ability, etc...
I am also skeptical of the claim that any and all observed variations in the above can be explained purely through biology/genetics.
Subsequently I'm skeptical of the claim that if meaningful biological differences between groups exist, that the effect size of these differences outweigh the effect sizes of individual variance and/or other cultural and economic factors.
In short, I feel like the OP and his allies are stacking unfounded assumptions atop unfounded assumptions and there's really nothing more to say than that.
The charitable reading of this statement is that you're skeptical IQ tests perfectly measure what you consider intelligence. I don't think anyone would say that IQ tests are perfect and always a perfect reflection of someone's cognitive ability, but when you test large groups of people, which is the data that we're actually talking about when we talk about IQ in the HBD context, these individual-level objections don't apply. If you think there are factors beyond what an IQ test measures that matter for life outcomes then no one will disagree with you, but your skepticism of this point is sort of a nonsensical reason to be anti-HBD since since racial gaps exist on every standardized test that could reasonably called cognitive in existence, including job-specific tests like fire chief qualification exams. Also, IQ does correlate pretty well with positive life outcomes, so even if it's one of many factors (just like race in college admissions) it seems to be a pretty important factor.
That being the case, your position of basically denying there's a cognitive ability or "merit" gap (as in the people who would be hired meritocratically into cognitively demanding jobs) is untenable even if you think IQ is complete nonsense. Anti-HBDers who have any idea what they're talking about don't deny the achievement gap, they argue the causes are non-significantly genetic. Also, "correlates directly" is simply not a statistically literate thing to say.
I think it probably does (although again, the phrase "correlates directly" makes me grimace), but even if it didn't, I'm not sure what the relevance is. If IQ and other positive qualities were completely uncorrelated, we would still expect racial gaps in anything cognitively demanding. This is an argument against viewing higher IQ people as inherently better people, not for IQ or other measures of cognitive ability being useless metrics, even though the latter is the way you're trying to use it.
"purely genetics" is doing all the work here. If, say, 70% of the gap is genetic, HBDers are right. likewise with "any and all variation". Why are you committed to the achievement gap being 100% XOR 0% genetic? Also, could you commit to whether you think the achievement gap is real or not? By this I'm asking whether you think the ubiquitous racial gaps on standardized tests imply an actual difference in the desirable traits being measured like future job performance, achievement in school, and, admittedly more nebulous, cognitive ability.
This is a dumber version of Lewtonin's fallacy. When we talk about entire population groups, individual variance doesn't "outweigh" population-level effects, that's nonsensical. If you're saying that HBD being true doesn't preclude the existence of smart black people then yeah, obviously.
The cultural/economic factors part is closer to a sort-of defensible position (although I'd like to see you explain racial SAT scores separated by parental income and education level) but you ruin your own point by using the word "meaningful" before them. If meaningful biological differences between groups (that impact traits we care about) exist, HBD is correct!
I feel like the charitable reading of the statement is the plain reading of the statement. I also feel that I already gave a clear definition of what I think "intelligence" means.
I Think that the reason you're grimacing and is that I am questioning beliefs that you hold dear.
No you didn't. IQ tests can be administered by anyone. Hlynka-intelligence can only be measured by Hlynka observing individual in real life setting. Nobody else here shares same idea about intelligence, not even most extreme anti-hbd.
I think I did, see; the ability to recognize, retain, and reason from/act upon changing information states.
Is this information enough for another motte user to conclude from it that median African cab driver is more intelligent than median motte user?

There are many people who disagree with HBD. It's such a niche and taboo view that I'm not sure how any proponent could get upset by disagreement. It's hard to see anything but disagreement. The reason I'm grimacing is that your reasoning is extremely bad and the way you use words like correlation (which comes up a lot in this debate because of how much evidence is statistical) is sloppy to say the least.
...and yet here we are.
As for the alleged "sloppiness" I'm not sure what you're referring to, but the first thing that comes to my mind is the old RA Heinlein bit about "witness mindset" Q: What color is that house? A: this side of the house is blue.
