That's a Jєωιѕн ranking system to classify goyim. Invented by William Stern.
Are you going to point out how, exactly, that system is flawed, or what makes its data worthless? If not, you're simply committing an Association Fallacy.
Presumably, the Jєωs wouldn't put a
broken ranking system to work to give themselves a lot of false data, right? If anything, the fact that Jєωιѕн media goes out of its way to
suppress and explain away racial IQ data might be an indication that that ranking system works a little
too well. It is, after all, in accord with what common sense, observation, and anecdotal evidence has always told those of us honest enough to admit it: That blacks -as a group - routinely display lower intelligence than other racial groups, and a concomitant disproportionate propensity for violent crime, consistent with the impulsivity and shorter time preferences that comes with lower intelligence. In short, it destroys the Jєωιѕн narrative that "Racism" is the reason for all of black peoples' ills. "Oy vey! Soch meshugaas this whole "IQ" thing was!"
I mean, for crying out loud, 2+2=4 is now being called "racist." That insane level of rhetoric wouldn't be called for if the intelligence gap between whites and blacks were not so stark and ineffaceable.
So, if it's a Jєωιѕн invention, it's one that's blown up in their faces. It certainly wouldn't be the first time for these blowback artists.
