There has always been a large controversy over whether inherited genes or the environment influences and affects our personality, development, behavior, intelligence and ability. This controversy is most often recognized as the nature verses nurture conflict. Skinner talked a lot about natural selection in that we, as a species, must choose to learn as we progress to be able to survive as long as possible (Catania, 2003). This theory was a huge part of the battle between nature and nurture because Skinner’s arguments have so much science and testing behind them and his experimenting proved his hypothesis. Some people believe that it is strictly genes that affect our ways of life, others believe that it is the environment that affects us, and some believe that both of these influence our behavior. Either way, social scientists have been struggling for centuries deciding whether our personalities are born or made. Tests are done often on identical twins that were separated to see how they are each influenced by their separate environments.
In the past twenty years, it has been discovered that there is a genetic component to every human trait and behavior. However, genetic influence on traits and behavior is partial because genetics can account, on average, for half of the variation of most traits. Researchers are finding that the balance between genetic and environmental influences for certain traits change as people get older. Also, people may react to us in a certain way because of a genetically influenced personality and, we may choose certain experiences because they fit best with our instinctive preferences. This means that our experiences may be influenced by our genetic tendencies. One way researchers study the development of traits and behaviors is by measuring the influence of genetics throughout ones’ life span, and it is found to be that the genetic influence on certain traits increase as people age.
