The dominant role of heredity in determining IQ is not a theory, it's an established fact, the consensus of hundreds of studies conducted in different times and places by many different researchers.

In reality, the majority of researchers in the field of intelligence testing believes heredity is the more important factor (Snyderman and Rothman, 1988).
