2.which of the factors explaining the Flynn effect do you accept?
All the factors explaining the Flynn effect are true to some extent, they do have an impact but I think the factor of Education is more dominant than other factors because I believe that intelligence and wisdom comes from education. A person who is high-educated and a person who isn't, can’t be equal in their mental ability.
3.If the Flynn effect is true, does this undermine the theory that IQ is mostly inherited? Why or why not?
It is generally accepted that intelligence is not inherited but can be related to the environment . None of us was born with a huge IQ or with low IQ . Just because the parents of a child are intelligent does not mean that their child will be as intelligent as they are. But it depends on the environment we grow up . If we make use of the potential we have inherited or not . Intelligence can be trained even when we have already become adults .
