Do you guys remember the Bogle family'? Twenty eight out of thirty four people from the Bogle family have been or still are in jail. The other two who did not go to jail either hanged themselves or got shot and were killed by the police. When we studied about them, I found them very interesting and started thinking whether nature is more important to determine who we are or nurture is more important.
There have been many debates about nature vs. nurture among psychologists to figure out which one determines who you are. They have invented adoption studies, twin studies (which the Psychology department of the University of Minnesota is famous for) and family studies. Nowadays, it is more acceptable to think that both the environment you grew up in and your genetic makeup are important. However, I wonder which one contributes a tiny bit more when people turn out to be criminals like serial killers. I found an interesting video clip about this topic from TED.com and want to share it with you before we discuss more.
So according to Professor Jim Fallon, the major violence gene called, MAO-A, that is on the X chromosome has to do with these psychopathic killers. When people have more MAO-A genes and have been exposed to violent things, it makes them to become criminals like murderers or serial killers. Isn't that interesting?
So my question here is would it be possible for us to use this data and research to predict serial killers before disasters occur like in the movie, Minority report?
