Hello Greg. I do not focus on epigenetics because, as I wrote in an earlier comment, in searching for and understanding the causes of psychosis and emotional distress, we must look outside of the body, not inside. Internal processes, even if relevant, distract from addressing the outside causes. To better understand this point, just think of any type of mistreatment or oppression that people experience or suffer. As one example, if a child is bullied at school, we must focus on stopping the bullying and creating a bully-free school environment. Studying the bullied child’s brain and genes would be a distraction from making the necessary changes in the environment. There are countless other examples.
