Give priority to humanity. Films by rating, biographies of celebrities. High aikyu is respected in an educated society, but only those who live by conscience are geniuses.
The level of intelligence is influenced by many factors, and hereditary is one of the main ones. An analogy can be drawn with growth, which is also largely determined by genes received from parents. Of course, in the case of intelligence, and in the case of growth, nutrition and training play a role, but within certain genes.
Increasing the rating in tests does not affect the development of intelligence. This is just a way to cheat the test, because questions by the creators of the test are selected in such a way that the experience and knowledge of the test takers do not influence the result. Those. so that the tasks in the tests were unexpected for the subjects, and the "competition" in the tests would be fair
The finding from the largest ever genetic study of childhood intelligence adds yet more fuel to the debate over whether intelligence is a product of nature or nurture.
I can only say that it is not necessary to have an IQ of 150+ to be a genius. For example, Richard Feyman, an outstanding physicist (you can read it on the internet) had an IQ of 122, and Marilyn vos Savant, a simple journalist, has an IQ of 210.
IQ does not show the level of your intelligence in any way. For example, according to the last test, I don't know how much you can trust him - 157, but I'm dumb as a cork.
There is a double-edged sword: if there is a desire to increase the rating specifically in tests, then, as with any cyclical activity, it must be repeated many times until the desired result is obtained; if the task is to become a genius, then it will be much more difficult ... Nevertheless, this level of aikyu is still most common among ordinary people. In other words, genius as such does not in any way correlate with the iq score.
