s found that one gene exists in aggressive individuals and not in non-aggressive individuals it is not determined if the genetic information causes aggression or if aggression causes a change in genetic information. Biological theories are strong in that the choice of treatment is obvious and it has been shown to be effective. Genetic theories' weakness is that it does not explain every case of aggression. These theories also put the responsibility within the individual. The bottom line of biological theorists is that a person's environment does not affect his aggressiveness. A weakness of behaviorist theory is that it seems unrealistic to think that all cases of aggression are learned in a stimulus-response manner. Aggression can be learned in other ways, such as through modeling and imitation. Both biological theories and behavioral theories have some weaknesses due to the fact that they do not have immense amounts of research to support them. The theories do not effectively explain the development of aggression in children. In closing, there is still an immense amount of work to be done in explaining the development of aggression and its true causes. There will always be one side who says there is a certain factor that causes aggression, while the opposing side will give a completely different cause. Many people believe that humans are violent because we are naturally and unavoidably aggressive. This widely held theory provides us with harmful expectations, self-fulfilling prophesies, and with excuses for being aggressive. The good news is that the evidence shows that humans can in the right circumstances and with appropriate training be kinder to one another. The bad news is that thus far, we seem to be loosing the battle against violence. We are all exposed to a myriad of responses to frustration, but in many ways the message again is: aggression gets results....
