Do environmental factors like poor education invalidate IQ?

Do environmental factors like poor education invalidate IQ?

This misunderstands why IQ matters. IQ has been correlated with longer life spans, higher earnings, ability to survive battle, lower chances of being a victim or perpetrator of crime, better ability to make money with investments, and overall higher wellbeing.

International tests and available data suggest we have a low average IQ as a nation, but they also show a very bad track record with academic performance - the average student does not pass senior year in high school.

The IQ scores still matter, because of the correlation with success in life. There are jobs people with poor learning abilities thrive in, but those are the very jobs the state is trying to eliminate.

Whether you want to call it poor academic performance (Poor Crystallised IQ) or poor IQ (Dynamic IQ), the fact remains, we either need to learn how to teach South Africans to learn and adapt better, or we need to allow the economy to produce jobs which those not inclined to academic ability, or abstraction, can thrive in.
