"Without offering any data on all that occurs between conception and the age of kindergarten,
they announce on the basis of what they have got out of a few thousand questionnaires
that they are measuring the hereditary mental endowment of human beings.
Obviously, this is not a conclusion obtained by research. It is a conclusion planted by the will to believe.
It is, I think, for the most part unconsciously planted... If the impression takes root that these tests really measure intelligence,
that they constitute a sort of last judgment on the child's capacity, that they reveal "scientifically" his predestined ability,
then it would be a thousand times better if all the intelligence testers and all their questionnaires were sunk in the Sargasso Sea."
