are some people born clever, and others born stupid? or is intelligence developed by our environment or experience? strangely enough, the answer to both questions is yes.
on the one hand, if we take two people at random from the crowd, it is very likely that their degrees of intelligence will be completely different. however, if we take two identical twins, chances are that they will be as intelligent as each other. therefore, a conclusion can be drawn 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 in intelligence.on the other hand, though, if we put two identical twins in different environments, for example, we might send one to university and the other to a factory where the work is boring, we would find differences in their intelligence several years later, which indicates that environment does play a crucial role in our intelligence.
just as every coin has two sides, our intelligence is partly born and partly developed. the sure way to develop our intelligence is intelligent parents as well as a good environment.
