    BEST BOOKS ON THE IQ QUESTION
    Via a friend on Quora that I frequently share:

    1) If you want something basic:
    Intelligence: All that matters, S.J. Ritchie, John Murray Learning, London (2015).

    2) Probably the best starting point:
    Haier, R. J. (2017). The Neuroscience of Intelligence, Cambridge University Press.

    3) If you want easy reading, lots of information, and one of the best sources of how IQ impacts life outcomes:
    Hernstein, R. J., & Murray, C. (1994). The Bell Curve: Intelligence and Class Structure in American Life. New York: Free Press. Note: The only shortcoming of this book is its age. We have powerful new technologies that were developed later. Those confirm the contents of The Bell Curve, and show that the book understates many factors.

    4) If you want to read the most cited text in all of intelligence research:
    Jensen, A. R. (1998). The g factor: The science of mental ability. Westport, CT: Praeger. Note: This book is more advanced than those listed above and also was written before the development of such things as brain imaging technologies (they were just beginning); genome wide association studies; and polygenic scores.

    Note: I also rely on another one whose title escapes me at the moment but gets into detail on the psychometircs and the evolution of testing. If I recall, it’s extremely expensive, and I had to get it from libgen.

    5) For a worldwide view:
    Richard Lynn: The Global Bell Curve: Race, IQ, and Inequality Worldwide. Lynn is controversial but I’ve spent enough time with him personally that he’s rock solid on the data.

    6) Much more on Jayman’s Reading List (search for IQ)
    I copy it here in case it’s ‘cancelled’.

    (a) at present about 10% of soldiers actually fight (b) of that 10% only about 80% will actually fire a weapon. We don’t know how many will shoot to kill. (We assume it’s up from 15% who will actually try to hit an enemy in vietnam. It was worse in korea and ww2.) (c) it’s been…

    I have a hard time understanding IQ deniers – other than they don’t seem to grasp the difference between (g), IQ, and Demonstrated Intelligence.

    (BTW: Thank you to @KirkegaardEmil for your work.)

  • Explanation please? Perception = disambiguation and organization of senses into

    Explanation please? Perception = disambiguation and organization of senses into models and memories of models into episodes. Prediction = auto association between the model and episodic memories and their constituent compositions. Valuation is determined by bias, with male and female biases well understood – as they are the origin of all human differences in bias. The sex difference is bias is prey, empathizing, in time, maximizing consumption for status, and avoiding risk and responsibility, limiting cellular damage, vs male predatory, systematizing, over time, maximizing capital for status, by seeking risk and responsibility despite accumulated cellular damage. ie: feels vs reals turns out to be true. That’s just the ‘nice’ positioning. The fact that women display vastly disproportionate mental illness ad social antisociality even if men more obvious physical antisociality, and women can’t avoid magical thinking, conflate approval with truth and disapproval with falsehood, likeability with competency, are addicted to hyperconsumption, attention-seeking, emotional activation, hypergamy as hyperconsmption, and devotion in time but not loyalty over time, is just the beginning of our sex differences.
    The culture war consists largely of the feminine counter-revolution against Darwin, fed by a credentialed elite assisting them in social construction (religion) that allows those elites to obtain power by the false promise that evolutionary laws are violable.
    Lying doesn’t help anyone.

    We can compensate for dyslexia by different tests. Because dyslexia is a perception problem not an association or prediction problem. So it’s akin to being deaf or color blind. Dyspraxia on the other hand can produce other defects.

    They don’t disappear when we get to the country level. At all. (Where are you getting this nonsense information?)

    I keep a huge spreadsheet of all differences by country then organized by civilization. There is perfect correlation between average IQ of the country and aggregate behavior in the country. In fact, IQ is the greatest predictor of not only individual but group behavior. ANd more importantly, given that human groups need to cooperate commensurably, then your DEMONSTRATED intelligence is more regulated by the people in oyur country than by your own. In other words lower IQ people drag down upper IQ people, and it’s non-linear.
