I chose to watch the TED Talk Jim Fallon: Exploring the mind of a killer. I was drawn to choose this post because I have always been interested in different serial killers and their stories. I have also always been interested in what makes them kill people and why they are the way that they are. This TED talk talked about how there are different chromosomes in males and females and there is a certain gene that people can inherit and if kids with that gene experience a major trauma in their life, then this can lead to them being a killer themselves.
I did find this presenter and the information to be trustworthy because of his background and his knowledge of killers previously. Also, Jim Fallon, the author, was a Sloan Scholar, a Fulbright Fellow, and he was a Professor if Neuroscience. He has researched towards the subject of psychopaths and he focused on killers, so he has a large, reliable background on the topic of his TED talk.
A research idea I could do to test this would be to compare the data of a human brains at a young age with the potential psychotic gene and compare them to the brains of children who have the gene and have experienced trauma to see the difference in the brain scans of someone who is sane compared to the brain of someone who is considered to be a psychopath.
