In addition, there is the ability to store a lot of data in the form of memories. And you can also use knowledge about something here and now, at the moment. And all these are components of intelligence.
Is intelligence still due to genetics? Of course, genes play a role. However, such things as the environment, upbringing, life experience, education also have a great influence on the formation of intelligence. At the same time, heredity is definitely a significant component: that is, a person’s intellect will be close to the intellect of his parents, regardless of upbringing.
It can also be unambiguously argued that IQ tests are not able to accurately determine the level of a person’s intelligence.
