2: they do have some sub-Saharan admixture due to proximity, but more importantly, both Judaism and Islam promote close cousin marriages, and when this is a dominant practice, it leads to the emergence of recessive genetic diseases, many of which reduce intelligence.

That sure is something I had not considered. Thank you.

is it a meme that jews are more inbred yet also intelligent then? or can they be both if they select more for intelligence

Whatever effect Jewish inbreeding has had on their intelligence, it has had notable dysgenic effects as well. They have a genetic predisposition towards neuroticism and a variety of personality disorders.

I don't believe Jews are any more intelligent than Europeans. See Ron Unz: The Myth of American Meritocracy - Jews are vastly overrepresented in positions of power relative to their academic merit. They're just effective networkers, and ruthless.

Inbreeding can cut both ways. Even some of their neurotic/obsessive compulsive traits that can be problematic are also necessary or at least more prevalent in people dedicated to a field which ultimately advances that field, i.e. the dedication (obsession) that many rabbis have for their texts is no different than how some Jewish intellectuals/artists/etc., have relentlessly pursued excellence in other fields.

The thing is, they aren't more intelligent. I've heard they test higher on things tested by the IQ test but tend to fail at other important factors of intellect not accounted for by the standard IQ test. I don't have any sources for this but it's something I'v heard quite a bit. Some time I'd like to investigate this and see if I can find any sort of proof.

IQ accounts for memory, processing speed, verbal intelligence, spatial, and perceptual reasoning. See WAIS-IV subtests. IQ also has high correlations with creativity, or divergent thinking tests. Any part of what we consider intelligence not accounted for IQ is probably very insignificant or not intelligence at all.

I dont believe that at all. Richard Feynman is one of the greatest physicists of the 20th century and he's on record as having scored a 125 on a school IQ test. When they did prefrontal lobotomies it was noted that the procedure usually had little to no affect on IQ score, despite the victim being regarded as profoundly different by the people that knew them. There are countless examples of people with super high IQ scores that didnt create or accomplish anything of note.

I'm not saying the tests are worthless. If you score really low on one its safe to say you probably arent going to cut it in a cognitively demanding profession, but there are clearly people with similar IQs that vary greatly in some abilities that are definitely a product of the mind.

I took one many years ago and felt like the verbal portion was something that is highly impacted by being well read, or being exposed to similar tests or mental tasks. In the days before the internet, growing up with an encyclopedia in the home would probably boost someone's IQ score significantly. I'm not saying this because I'm bitter either. I scored slightly higher than Feynman allegedly did, despite struggling to pass physics in high school. I knew other people who scored lower than me that were clearly more intelligent and quick thinking. It was a nice ego booster, but ultimately meaningless aside from proving that I wasnt an idiot.

IQ tests like WAIS-IV also measure the crystallized portion of verbal intelligence as well (VCI) but you can see your fluid intelligence separately on this exam.

Crystallized portion of verbal IQ is not very impactful on your FSIQ. Not all subtests are weighted the same.

https://en.wikipedia.org/wiki/Wechsler_Adult_Intelligence_Scale#Verbal_IQ_(VIQ)

You'll also see how little vocab impacts your FSIQ found as only 1/4 subtest of VCI which is itself 1/2 of VIQ.

As for the Richard Feynman example you've mentioned, and people with high IQ scores not accomplishing anything of note, it is clear there are things just as equally important as intelligence for success like conscientiousness.

The thing is IQ tests often do not account for one or more of those useful categories, or under-utilize it. I've heard anecdotally that Jews test well on things like verbal IQ but then test worse in other categories.

Yes, Jews score below average in visuospatial intelligence.

they do have some sub-Saharan admixture due to proximity

What is the average sub-Saharan DNA in Middle Easterners? Iran has an average IQ slightly below African-Americans, I doubt Iran has any significant sub-Saharan DNA in the average person.

[–][deleted] 3 insightful - 1 fun3 insightful - 0 fun4 insightful - 1 fun -  (1 child)

This study suggests that Iran's average IQ is actually 97. It is an Iranian study, though, so maybe take it with a grain of salt.

And note that only about 65% of the Iranian population is ethnic persian
