False. IQ is 80% genetic by our late teens. http://www.fdrurl.com/iq https://twitter.com/Stfko_memero/status/1159118883577614336 …

How can you separate cause from effect in the IQ question? It seems like a chicken or the egg, nature v.s. nurture, correlation is not causation, and all that business.

Because you can look at early age IQ of people in low SES families. Someone with a high IQ from a poor family will have better life outcomes (income, life expectancy, etc) than someone from a middle income family with low IQ. With enough data you can untangle causation.

Yes but the predictive capability only occurs at the lower end and as it goes up eventually it loses it prectibality.Somewhere in the 90s. IQ was meant for pointing out disabilities not skill assessment.If skill assessment,one need to use a power law NOT Gaussianpic.twitter.com/eHYx9W3lY1

You're literally repeating Nassim Taleb's mistakes based on one study from 2007. Specifically, this one : https://www.gwern.net/docs/iq/2007-zagorsky.pdf … The "prediction only in the tailend" idea is not at all an accepted and settled perspective among IQ researchers, and is in fact an outlier position.

Also, you're talking specifically about the correlation between IQ and income, where we would expect to see *some* level of non linearity. Here's a 2018 study with a sample size over a million: https://www.sciencedirect.com/science/article/pii/S0160289618300278 ….pic.twitter.com/pGw0az69aH

Finally, Predictive power about other things, such as Job Performance, is not included in that first study. . Here's a metastudy of 174 studies: https://experts.umn.edu/en/publications/linearity-of-ability-performance-relationships-a-reconfirmation … Non linearity best describes the relationship of IQ to job performance a mere 6% of the time.

I've read just about majority of infamous paperwork from Minnesota twins to Flynn effect. Methodologies are always. When I ask what my Maths prof think, he says the there's a long history of statistical malpractice and errors with IQ research

Math profs aren't usually qualified to judge work in psychology. They suffer from a lot of 'STEM superiority disease', thinking one can competently evaluate work with completely different methods because one hails from a high quality field.

No, Mathematician criticise the vigorness of Psychology/Social scene and the weak implementation on Stats. Of course many psychologist will take an offense because its their career but its true especially when many psychologist don't even know A-Level (college) errors of Stats.
