Numerous studies have shown statistically significant correlations between height and IQ, even when controlling for socioeconomics and education. The correlation exists in both the developed and developing world and persists across age groups. Height has been shown to be a good predictor of IQ.

>Birth weight showed no association with childhood IQ. However, height at age 9 years was a significant predictor of childhood IQ after adjusting for socioeconomic status
https://doi.org/10.1093%2Fije%2Fdyi038

Dutch twin study find there are genes that can affect both height and IQ at the same time:
>In adulthood, a correlation was found between height and FSIQ in young adulthood and between height and VIQ in middle age. All correlations could be ascribed to genetic factors influencing both height and IQ.
https://www.ncbi.nlm.nih.gov/m/pubmed/17081263/

Environment plays a role, but not entirely:
>A major part of the height–intelligence correlation was due to correlated shared environments (59% of the phenotypic height–intelligence correlation), but statistically significant effects of correlated genes and nonshared environments were also found (respectively 35% and 6% of the phenotypic correlation).

It's certainly possible that tall people, being naturally more desirable, would only be mating with the most successful people. This could have created a selective breeding situation that leaves tall people with superior cognitive genes as well.

Uh, no retard. I'm not risking him being one of the outliers of tall people with low IQ. I will always make real-world accomplishments a strict requirement. However, that will statistically give higher odds of it being a tall person.

top fucking kek
both height and IQ are correlated with nutrition aka access to high quality fooda and parents' wealth, there's your answer retard
had you provided the entire population with the same access to food and nutrition, there would be no correlation between height and IQ

Not every study has to control for everything, that would be impossible. You make a consensus based on a body of work to combine their individual findings. Socioeconomics has been ruled out as a confounder. It plays a factor of course, but the trend persists outside of it.

Typical manlets. Just glancing at a single image and drawing conclusions. How about looking at the studies? That's how you do real science, and the science says there are strong correlations genetically.
