Buddy, if you doubt my credentials, again, just ask me for LinkedIn privately and I'll send you the link...Also numerous people on this forum know me in real life..for example..batbdotb just crushed an 8 day home retreat with me at my house last month. You are welcome to come join the next time we do it.

>The core part of this discussion that you've had trouble overcoming since the beginning is you're just not familiar with the way that these types of discussions are conducted, so you shoot from the hip and make pop-psych, sweeping generalizations that someone who's seen some TED talks thinks is the scientific process.

LOL, oh you know how intelligence testing is discussed by people in the field? Do you know this from your years of experience as having a friend or two who learned about intelligence testing in a class in college?

>31 year old reference to support their point, and doesn't know that an academically trained person would comment on that.

You are being dishonest, I also pointed you to a book by Dr. Stuart Ritchie that was published in 2015 and summarizes all the latest research.

Here are more references

" intelligence testing is one of the great successes of psychology (Hunt, 2011). Intelligence test scores predict many real world phenomena and have many well-validated practical uses (Gottfredson, 1997; Deary et al., 2010). Intelligence test scores also correlate to structural and functional brain parameters assessed with neuroimaging (Haier et al., 1988; Jung and Haier, 2007; Deary et al., 2010; Penke et al., 2012; Colom et al., 2013a) and to genes (Posthuma et al., 2002; Hulshoff Pol et al., 2006; Chiang et al., 2009, 2012;"

This is an interesting question, and it's a question that I don't know the answer to.

I'll give you a brief outline though of what I know about the possibility of increasing one's IQ/intelligence (the relationship between IQ and intelligence is itself a complicated subject).

First lets deal with heritability of IQ. The most popular estimate of the heritability of IQ among adults seems to be 0.8 or 80%. This is the estimate I've read from the APA (American Psychological Association) and from reading other sources on IQ.

However a common misconception that many people believe is that an 80% heritability means that 80% of one's IQ is due to their genes, which is wrong. What 80% heritability actually means is that 80% of the variability in IQ within a population can be explained by genetic differences.

Here's a quote from a University website that explains it with an example

http://psych.colorado.edu/~carey/hgss/hgssapplets/heritability/heritability.intro.html

>Heritability and environmentability are population concepts. They tell us nothing about an individual. A heritability of .40 informs us that, on average, about 40% of the individual differences that we observe in, say, shyness may in some way be attributable to genetic individual difference. It does NOT mean that 40% of any person's shyness is due to his/her genes and the other 60% is due to his/her environment.

Next lets deal with the Flynn effect.The Flynn Effect is the observation that for the past few decades, there has been an increase in average IQ by 3 points every 10 years. The relevant question here however is, does this imply that people are getting more intelligent? I personally don't know the answer to that, and I'm not sure if there is a settled answer in the psychometric community. However I do know that Flynn himself has expressed doubt on the view that we are getting more intelligent. I will provide 3 supporting pieces here:

Flynn himself has written in an essay (that I unfortunately have lost and have been unable to find for a few months) that he does not believe that the Flynn Effect is caused by an increase in general intelligence/g/g factor (this is a technical term).

https://en.wikipedia.org/wiki/G_factor_(psychometrics)

There is also empirical evidence from psychometric research that the rise in average IQ (I.E. the Flynn Effect) is correlated negatively with the g-loading of a test. In simple language, this just means that broadly speaking if an IQ subtest relies heavily on general intelligence, there has been a smaller increase in the average than on IQ subtests that don't rely heavily on general intelligence.

http://www.sciencedirect.com/science/article/pii/S0160289613000226

There is also the question of if an average IQ increase of 3 points does not mean we are getting more intelligent, than what does The Flynn Effect mean?

Flynn himself has a great TedTalk answering this question, since as I mentioned before Flynn himself does not believe that we have gotten more intelligent. A TLDR of his explanation is that he thinks The Flynn Effect is due to a huge shift in the way we are taught to think about things and how we view the world. In his words, he believes humans have developed more sophisticated "mental artillery."

Lastly if you've been bored by my blathering here and just want a straight forward "Yes" or "no" answer, like I said I don't know the answer. However I do know two experts who each express the opposite answer to the question.

In this book written by an intelligence expert, he claims that little can be done to increase one's IQ however over a person's lifetime their fluid IQ will peak in their mid/late twenties then slowly decline thereafter whereas people's crystallized IQ steadily increases throughout their life

Whereas I have emailed Flynn before about a question related to this question, and he told me that in his book (that I will link below) he explains why he thinks that it is possible to increase one's IQ through hard work.

This book could be what you're looking for. It's more of a survey of IQ research in general, not HBD, but it does touch on racial differences.

Not g (maybe?) or gap related, but it seems education improves IQ generally.

Stuart Ritchie, intelligence researcher and author of Intelligence: All That Matters has a paper here the abstract of which I will quote below:

>Intelligence test scores and educational duration are positively correlated. This correlation can be interpreted in two ways: students with greater propensity for intelligence go on to complete more education, or a longer education increases intelligence. We meta-analysed three categories of quasi-experimental studies of educational effects on intelligence: those estimating education-intelligence associations after controlling for earlier intelligence, those using compulsory schooling policy changes as instrumental variables, and those using regression-discontinuity designs on school-entry age cutoffs. Across 142 effect sizes from 42 datasets involving over 600,000 participants, we found consistent evidence for beneficial effects of education on cognitive abilities, of approximately 1 to 5 IQ points for an additional year of education. Moderator analyses indicated that the effects persisted across the lifespan, and were present on all broad categories of cognitive ability studied. Education appears to be the most consistent, robust, and durable method yet to be identified for raising intelligence.

> If I want to learn more about this stuff, where do I start?

Not sure if it covers all that you're asking for, but if you want to get a solid base on intelligence and the research on it, here are a few good starting points published in the last year.

…ou alors peut-être que l'auteur s'est intéressé à l'état de la science sur le sujet ?

Si tu t'intéresses au sujet (et que tu parles anglais), tu devrais lire ce petit livre. Il n'est pas écrit par un journaliste mais par un chercheur spécialiste du sujet (lui) et est la meilleure introduction que j'ai vu sur l'état de la recherche sur l'intelligence pour le grand public. Ça devrait te faire reconsidérer ta vision des choses.

Try reading actual experts, since Murray is a political scientist like me with no qualification in IQ.

INTJ generally when taking such tests, but I can't say that I consider them all that worthwhile.

I take the Stuart J Ritchie approach to IQ (he's the author of Intelligence: All That Matters) ... that it's valuable to be aware of the concept but not particular worthwhile finding out your own.

> BR: Is there any reason why a person would want to know their IQ?

> SR: I don't think it's particularly useful.

> I don't know what my IQ is. One of the guys in the psychology department here knows, because he tested me. And there's always a slight awkwardness when we're talking about IQ. He knows what my IQ is. But I have not, and I have no interest in knowing.

The easiest read you're going to have on this is Stuart Richie's Intelligence: All That Matters

In the scientific literature there is an r-factor of between .5 and .8 for the genetic heritability of IQ, with the rest being environmental factors - predominantly non-shared environment. The variance between .5-.8 in the relationship between heritability and IQ comes largely as a matter of when people are tested. Child IQ leans closer to .5, suggesting greater (nonshared) environmental effects, while adult IQ measures closer to .8.

If you want a really serious look at this, and if you actually gave a shit, you'd read Steven Pinker's The Blank Slate.
