And that range is smaller than the difference between your ability to perform cognitive tasks and the average high school dropout's ability to perform those tasks. Education makes a much larger difference.
- naasking 4y agoI disagree. Education boosts IQ scores by 1-5 points [1], where 1 standard deviation from the mean IQ score is +/-15 points. The spread on cognitive abilities is clearly broader than education can cover. [1] https://pubmed.ncbi.nlm.nih.gov/29911926/ https://pubmed.ncbi.nlm.nih.gov/29911926/
- lern_too_spel 4y agoEducation has improved the average IQ of multiple East Asian countries by 15 points over two decades. That's an entire standard deviation improvement for the whole population. One-on-one tutoring has been shown to make a two standard deviation difference. That's the difference between median intelligence and genius. https://en.wikipedia.org/wiki/Bloom%27s_2_sigma_problem https://en.wikipedia.org/wiki/Bloom%27s_2_sigma_problem Your study is about the effect of an extra year of badly done education on people who drop out of school, which is worth 1 IQ point. That same study shows that the effect of mediocre education on people who don't drop out of school is an increase of 5 IQ points.
