       For hundreds of years, psychologist and ordinary people have never stopped debating this fascinating question.Some people think personality develops as a result of the environment—the combination of influences that we learnfrom, such as our families, our culture, our friends, and our education. The people who believe this theory believe thatall babies are born without a personality and that it’s the environment that determines, or forms each child’s personality.This school of thought is called the “nurture school.”
      At the other end of the continuum we find people who believe that personality is determined by “nature,” or thecharacteristics we receive, or “inherit,” from our parents biologically, through their genes. These people believe that ourpersonality is not determined by the environment, but rather by genetics, and that each baby is born with a personality.The nature-nurture controversy is very old. Experimental psychologists have tried to discover which of these two factors,genetics or the environment, is more important in forming our personality. However, it’s very difficult, if not impossible,to conduct research on real people with real lives. There’s just no way to put people in a laboratory and watch themdevelop. For this reason, there’s no scientific way to settle the nature-nurture controversy. Recently, however, mostresearchers have come to believe that both the environment and the genes —nurture and nature—work together and areboth important.
