     Are some people born clever, and others born stupid? Or is intelligence developed by our

environment and our experience? Strangely enough, the answer to these questions is yes. To

some extent our intelligence is given to us at birth, and no amount of education can make a genius

out of a child born with low intelligence. On the other hand, a child who lives in a boring environment

will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits

of person's intelligence are fixed at birth, whether or not he reaches those limits will depend on his

environment. This view, now held by most experts, can be supported in a number of ways.

      It is easy to show that intelligence is to some extent something we are born with. The closer the

blood relationship between two people, the closer they are likely to be intelligence. Thus if we take

two unrelated people at random from population, it is likely that their degree of intelligence will be

completely different. If, on the other hand, we take two identical twins, they will very likely be as

intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar

intelligence, and this clearly suggests that intelligence depends on birth.

      Imagine now that we take two identical twins and put them in different environments. We might

send one, for example, to a university and the other to a factory where the work is boring. We would

soon find differences in intelligence developing, and this indicates that environment as well as birth

plays a part. This conclusion is also suggested by the fact that people who live in close contact with

each other, but who are not related at all are likely to have similar degree of intelligence.
