this is no longer true.

ONE IN THREE WOMEN WITH IQS OF <=90 HAVE UNIVERSITY DEGREES. ffs man, this is not 1970. standards are a thing of the past. Image
after uni there is probably more cognitive stratification, but not nearly as much as there should be.

This effect held in 3/3 of the national standardisation samples I checked, and using three different methods of g-loading estimation.

The g-loading–male advantage associations were all directionally consistent, and statistically significant in most cases. Image
Italians were an exception, as the gender ability profiles in their sample appear to be less differentiated. Strangely, Italian males even outperformed Italian females on some processing speed tasks. Image
Moving on, it’s immediately obvious that the cancellation subtest is a uniquely poor g proxy, and there is an intuitive way to demonstrate this: it is 2.79 standard deviations below the subtest mean correlation average. Image

On the individual level, higher intelligence has a protective effect against fatal car accidents, but does the same hold true when comparing populations?

It appears yes: national IQ correlates at r = -0.7 with country-level road-traffic death rates. Image

Is 'mansplaining' actually necessary?
It may well be, as women know much less than men in almost every domain. This is especially true for finance, the general factor of knowing about things, and science-related knowledge.

Evidently, men are not mansplaining enough: Image
You may be wondering "what's going on with factor 4?", and so did I. However, it ceases to be mysterious once you realize that factor 4 does not load at all on the second order general factor, and was also uncorrelated with factors 1 through 3. And look at the subtest loadings!Image
Despite being labeled 'humanities,' it is primarily defined by moderate negative loadings on Sport and Games, effectively indexing the absence of male-coded knowledge rather than humanities expertise. The former test is also the only one whose largest absolute loading was on F4.

This is not controlling for IQ. In a meta-analysis they found the openness–income association was largely, but not entirely, mediated by IQ.

Independent of intelligence, conscientiousness and extraversion are the strongest predictors of income: Image
The confidence intervals for the adjusted effect sizes are inferred. Here is the table from the paper: Image

if this makes you happy you’re part of the problem. Image
tbf ‘the problem’ is chiefly genetic, so it’d be more apt to say that if this (in the context of us living in a dysgenic hellscape) doesn’t remind you of how sick and degenerate civilisation is now, your sexual disgust response has been mutated out of you
admittedly, her being an autistic pervert is endearing until you consider the implications of her disposition.
