My personal take is that intelligence is much like muscular strength. Genetics probably play a role but the more important factor is how you use and train your cognitive strength. A cognitively sedentary person will almost always be less intelligent than a cognitively active person, I doubt genetics play a large role unless we’re talking about people who put similar levels of effort into their development and upkeep.
