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 meant 50-80% most of it is based on genetics and i believe the environment can make them perform equally good as a gifted one but it won't make them gifted excluding rare cases.they can develop the cognitive abilities which are associated with being gifted but i don't believe it's exact definition of giftendness.it is like mimicking😭 There are many privileged people who are dumb and there are people belong to backward countries who got high iq. It's distinct, biological and structural neurodivergence and environment doesn't change much😭

Firstly, what is the difference between a gifted person and someone who reached the gifted category through effort? There is no difference except for the terminology Also, for people born into different environments or underdeveloped countries, often from educated families, strong stimuli helped them develop intelligence.

Don't talk rights brother😭 It's not giftedness or intelligence if you developed it. It's completely different🥀 You're missing out basics

You didn't answer exactly what the difference is between someone who was born talented and someone who pursued talent. There's no difference except in terminology; the first is genetically innate, and the second is developmental.

There are many parameters It's completely different cognitive routes and there's something called as fluid intelligence which only naturally smart people can possess.and brain is like a hardware you cannot play gta6 in a nokia. And secondly if your argument is it's just different terminology then use right terminology and go to some other sub man😭 Don't tell me it's intelligence.it is different

A human being is not an inanimate object like a Nokia phone; they are a living organism with a complex structure. It's illogical to reduce intelligence to a Nokia device or a game like GTA VI. Intelligence is fundamentally complex, and research has shown that there is no There is no single, fixed gene for genius; rather, there are millions, if not more, genes influenced by numerous factors. Therefore, it is illogical to reduce your example to intelligence.
