Even after I finish studying Psychology 1001, I would remember the concept of nature versus nurture debate and twin study, because nature versus nurture debate was always in almost every area of Psychology when I studied. The reason that we could see this debate in many areas is that the debate is a basic knowledge that we all have to know throughout Psychology. This debate and twin study is related to psychological characteristics, IQ, and many other areas. The debate is reasoning about what makes human. In other words, what influences human being to grow, genetics or environment?
Twin study is a representative study to demonstrate this debate. This twin study is extremely consistent. According to the twin study, monozygotic twins are still similar even they are reared apart. This means that genetics is important. Also, it doesn't matter they are reared in the same environment, because adopted siblings shows no relation even though they are grown up in the same environment. However, the monozygotic twins are never perfectly identical, which means that genetics is not everything, and environment is also important. I know that this debate is endless debate that would not end or would not be concluded, but I also know that this debate is a very important concept that everyone has to know.
