Are some people born clever and others bornstupid? Or is intelligence developed by our environment and our experience?Strangely enough, the answer to these questions is yes. To some extent, ourintelligence is given us at birth, and no amount of special education can madea genius out of a child born with low intelligence. On the other hand, a childwho lives in a boring environment will develop his intelligence less than onwho lives in rich and varied surroundings.

Thus, the limits of a person’sintelligence are fixed at birth, whether or not he reaches those limits willdepend on his environment. This view, held by most experts now, can besupported in a number of ways. As is easyto show that intelligence is, to someextent, something we are born with: the closer the blood relationship betweenpeople is, the closer they are likely to be in intelligence.
