On page 242 of his book Are We Getting Smarter?, James Flynn claims the original Wechsler Intelligence Scale (WISC) normed circa 1947.5 yields full-scale IQs 7.63 points higher than those of its revision (WISC-R) normed in 1972. Stats like that are known as the Flynn effect; the notion that IQ is going up at rate of 3 points per decade. Of course by definition the average U.S./U.K. IQ is always around 100, but tests must be constantly re-normed to keep it that way.
However I have long suspected (and largely proven) that the Flynn effect is exaggerated by a statistical artifact. For example, when comparing old and new versions of the Wechsler, half of the test subjects will take the old version first and the other half will take the new version first, so whatever practice effect from being tested twice affects both tests equally. However I had a hunch (as had A.S. Kaufman) that you get more of a practice effect from taking the WISC-R first than from taking the WISC first, thus WISC scores will be spuriously high when people take both tests.
Finally I found some obscure old paper that proves this right. White kids who took the WISC-R first scored 12 points higher on the WISC than WISC-R, but white kids who took the WISC first scored virtually the same on both tests! When you combine the two groups together, the WISC appears 6 points easier than the WISC-R, but that difference is entirely driven by the subset of the sample that took the WISC-R first
A similar (though less extreme pattern) is found for non-whites.

Autists are serial logic process specialists.
The reason they have trouble with empathy is they don’t make assumptions.
They do not make guesses or read into situations, they just go by the data.
The left brain but extreme detail focus. very little right brain.
excellent observation and yes reading into things is very important for creativity and having the best perspectives on things. from social phenomenon to even science you need to do this (speculate) in order to get the best scenarios and answers necessary.
Can you send me links to your Flynn effect proofs of artefact? I had assumed this could be a big factor, but could not put my finger on it, as you have. Then I might encourage you to do a publication on it.
The relevant link is in the article but I sent you an email with it anyway. Thank you for your interest in this very important topic!
Cheers!
Oh so you answer this guy’s question before mine because he writes for Unz? BOOO
IIRC the WISC-III exhibited the same 3 points per decade gain, and that had more instructions than the WAIS-R and WAIS.

even indians recognize their inferiority.
That’s nonsense. They do not have the smallest brains.
india has such a multitude of diversity and ethnic heterogeneity that it is completely possible that something like this is true.
most ethnic groups would be comparable to other big brained caucasoids but a small group of ethnic groups might be very small. this might be attributable to Australoid admix in these communities/ethnic groups!
Australoid admixture is minimal. Also the indians with the smallest brains also have the smallest bodies. Brain to body ratio is what counts.
I ordered an Ancestry DNA test today. Pepe or anyone else here, are you interested in knowing the results? I can run it through Promethease too if there’s anything in particular you’re curious about
run it through genomelink promethease nebula get the ancestry dna traits do all that stuff. tell us every single detail your genetics tells us about you Ganzir. for the culture brother.
I’m not sure yet what I’ll post when I get my results. I’ll probably link my Promethease report
gentile autists are the worst. i mean why disparage the Jewish people when gentile autists have made far less productive contributions and have marred society with their presence far more significantly!
It would be hilarious to see who Greta ends up dating, if she dates at all.
hopefully some retarded aspie like Flamin that would be admirable since the two are known autists that are deluded enough to think that the world is run by them. sad news grand autists there is no such thing as autist supremacy and it is actually a pervasive syndrome not even a disorder that creates a mentally decrepit view of the world.
i strongly believe that despite being considerably less “intelligent” than Flamin and other autists at least according to what IQ tests would tell us i am much more fundamentally and generally sound in answering lifes questions than them.
pumpkin protects autists. he is someone who will go out of the way to shield and nurture these individuals because he feels like it is his moral duty to do so and to benign any harm these individuals might end up creating for this world.
pumpkin empathizes with autists. he believes by doing so his legacy will be built in correspondence to his status going up! he does not believe in truth. otherwise he would equalize opportunity for all commenters on this blog.
for so long i have seen pumpkin try to destroy my own legacy and tarnish my reputation for the gain of the people he empathizes with who carry his agenda out. he does not even post comments i create since my neurotypicality is so alien to these autists that he will never see the good in allowing people such as myself to flourish uninhibited.
Billy thinks MA had a high IQ. can this be possible? the thing i have a problem with is how much people on this site and the entirety of the internet have on placing their own agendas above the truth.
there are so many inconsistencies and contradictions in peoples worldviews that it tells me that not only are they dumb but that they are not dumb for having contradicting worldviews but for having such a demented idea of truth that they think it can exist with contraidctions.
if you wish to be truthful at the very least and properly understanding of the truth at its paragon then you must understand that truth cannot have contradictions in and of itself. logic cannot work if two things do not end up with a sum or product that has merit on its own terms and is completely sensible regarding all facets of its independent existence.
if something has contradictions then it is not logical anymore it becomes irrational and obsolete in the presence of a corresponding truth. actually false items in this reality can exist but only because their is a corresponding truth to it that makes it so that the illogical entity or idea is no longer justifiable and conceivable!
so does falsehood exist? yes! because of their correspondence to truth they do in fact exist. do they have any way of being implemented into the real world. it would depend on the falsehood but generally no.
autists like Flamin would disagree and say that falsehoods cannot exist. but they do! just look at your own comments for further background into the matter. infinity only exists because falsehoods can exist as well. do numbers exist? yes but only abstractly. i mean negative numbers dont really exist because you cannot have negative anything and zero is the ultimate beginning of everything. you cannot go anywhere below zero only label things as such.
so this is where illogical statements can be real because they rely heavily on making truths what they are: truth. they are a frame of reference. just like negative numbers. if this makes sense to you then your understanding of the abstract is potentially limitless since this is the basis of how truth is born.
