Most people give credence to biomedical research over biopsychosocial research, thinking, I suppose that biomedical research shows us about reality. I don’t want to argue that it doesn’t. What I do want to do is argue for the social sciences as giving us information about the nature of reality.
For example, we know that Holocaust survivors are at-risk for developing schizophrenia. This gives us reason to think that exposure to trauma, psychological hardship, and so forth, can trigger psychotic symptoms. What we can’t do is replicate those conditions, and randomly assign people to Holocaust-like conditions.
What we can do is look at other instances where trauma may have caused a break from reality. For example, we can look to the Ghost Dance.
I invite you to watch this video, and consider whether the restrictions of liberty, trauma, and hardship, etc., caused the break from reality which was the Ghost Dance.
