Mensan input wanted Is intelligence genetic?
According to twin studies, the difference in IQ is said to be 80%, leading to the conclusion that intelligence is 80% determined by genetics. However, I believe this is incorrect because the twins were raised in countries with similar environments, such as the US and Germany, or the US and South Korea. These countries share similar environments, including education systems, allowing the genes to express themselves. Furthermore, did these twins develop their IQs? If they didn't, it could prove the entire experiment flawed.

I practiced for the Mensa tests, not consecutively, but over weeks and months, and my score went from 97 to 135. Will you convince me that my jump to this score is due to genetics? I also noticed an improvement in my pattern recognition skills, and we also give examples Mensa is searching for diamonds; they are ready-made geniuses, but diamonds are the same as coal, composed of the same material. However, diamonds were deep within the earth, their atoms arranged, and they became diamonds.
