Several studies have suggested a weak link between looks and general intelligence of around r = 0.2. However, a more recent meta study found no correlation and suggested studies that claimed otherwise suffered from [[halo effect]].<ref>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4415372/</ref> | Several studies have suggested a weak link between looks and general intelligence of around r = 0.2.

Other studies have also found a weak, but consistent, correlation with IQ and height, (around r = 0.2-0.3 depending on age when tested and type of ability measured).<ref>https://bmcgeriatr.biomedcentral.com/articles/10.1186/s12877-016-0340-0#Sec15</ref> Different explanations for this correlation exist, ranging from superior childhood nutrition increasing both height and IQ,<ref>https://academic.oup.com/ije/article/34/3/678/682312</ref>assortative mating for both height and IQ leading to them being genetically linked,<ref>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3044837/</ref> or even that taller people have greater cortical volume in the brain, leading to greater intelligence on average.<ref>https://link.springer.com/article/10.1007/s00429-018-1675-4</ref> | |||
