First, I am not a white nationalist. Anyway, this fellow accuses me of lying when I said that Nuijten et al (2018) reported statistical power levels of 49% and 57% for intelligence research and group differences research because when he followed the link I gave for the paper...
...those numbers did not appear in the paper linked. The explanation for this is simple: he's reading the 2020 version of the pre-print whereas I cited the 2018 version when I wrote that article (in Jan 2019). The old version is still up on the pre-print site and you can see I...
...reported the numbers correctly. You could have said the paper had been changed and that I should analyze why/how it had been changed and see if it changes the force of my argument, but instead you decided to slander me and reveal you don't know how preprints work.
This lie is being amplified by this clown, a consistent spreader of vapid propaganda. I don't have much to say about him other than that he's generally a piece of shit, and so I want to highlight that he's also being retarded.

Anyway, I do think the paper now makes intelligence research look less good than it did in 2018. But me not citing data from the future is not a lie or a mistake.

I was going to make a blog or video about this, but I've decided to just make it a twitter thread (b/c lazy). This map is my best guess as to what is going to happen. The reasoning behind it is in the rest of this thread.
Generally polling for the presidency is pretty accurate. 2016 saw better than average national polls and worse than average state polls and those state errors clustered in swing states causing a large upset. The fact that the national polls were better suggests that...
...a significant proportion of the error in state polls was not due to "Shy trump voters", as that would distort national polls as well. Many pollsters plausibly argue that they under-estimated the number of white low-education voters last time and have adjusted for that...

Re-reading through academic work arguing against genetic models of racial IQ differences is reminding me of why I came to distrust academics so strongly. The level of dishonesty and incompetence really is astounding. This shouldn't really even be called a "debate"...
...This is just a random example but imagine being as dishonest as Nisbett and denying a within family correlation between brain size and IQ by only telling your readers about Schoemenn's study w/ 72 people and ignoring the contrary literature w/1000s despite knowing it exists..
Another example: Nisbett, Harden, and Turkhimer got around dealing with the racial gap not closing by literally just denying that the racial gap had been measured in the last 14 years. Just insane.

From the outside this kinda looks like a serious...

The finding that environmental variance in some traits is explained only by non-shared environments, and not at all by shared environments, is, while true, very confusing given that environments all presumably impact the same factors in the brain whether they are shared or not...
...and surely the brain doesn't "care" whether certain neurons were impacted by a shared or unshared environment, and"shared" / "unshared" seems like such an artificial distinctions it seems bizarre that they would map on so well to real vs non real environmental effects. Of...
...course, this all has an explanation, eg non-shared environments systematically impact different brain regions, but I don't know what it is in any detail, and any such explanation seems to require an explanation of its own. (Obviously, I'm not talking about traits where...

(1) Self report measures of personality generally fail tests of measurement bias for age and sex group comparisons. This study should not accepted without evidence demonstrating a lack of test bias for race. Many people pretend to care about test...

(2) bias and other methodological concerns when discussing IQ, but such concerns are largely fraudulent attempts to avoid uncomfortable truths by people who don't really care about psychometrics at all.

Also, general personality traits do not perfectly correspond to...
(3) any of the traits Kaufman mentioned. Non self-report data on crime and impulsivity, and even self report data specifically on sexual and work behavior, affirm all the differences Kaufman is pretending this paper refuted.

When called out on his bullshit...

How BS spreads, a case study:

-@JamesLingford cites Devlin et al as showing that the heritability of IQ is less than 60%

- Fails to note that this analysis is heavily based on children and the heritability of IQ increases with age...

- Devlin et al claim pre-natal influences bias twin studies of IQ

-Lingford neglects to mention that this has since been falsified by researching showing that similarity in the MZ pre-natal environment doesn't increase similarity in IQ...

link.springer.com/content/pdf/10…
-Kevin Bird shows up to cite old research with an inferior sample size as showing that there is a pre-natal bias that explained 14% and 10% of the variance in IQ similar to the estimates of Devlin

-Bird doesn't mention these estimates were for specific abilities and...

(1/9) @nathancofnas: Obviously, the relevant question is whether Jews are marrying people at random with respect to whether their mates are Jewish. We agree that the intermarriage rates of Jews cannot be taken to prove that they are ethnocentric because Jews may have...
(2/9) non-ethnic reasons for preferring to marry fellow Jews. This is one of the reasons for which I regard marriage rates as an inferior form of evidence.

What I'm not sure you have admitted is that you obviously cannot compare the intermarriage rates across groups to...
(3/9) establish a rank order of ethnocentrism because these groups differ in size and because, as you have said, reasons other than ethnocentrism can affect intermarriage rates.
