Is schizophrenia caused by frequent and severe betrayals by family members, as well as gaslighting? Upon betrayal, the brain blocks our the incident. It then searches for a perpetrator, not in the family member, but in the world at large, leading to paranoia. Additionally, the pain itself is often also blocked, and therefore victims may not even realize their paranoia is motivated by a personal injury.
I already know the physical development theory. Different thought patterns developed different neural circuits, and differently built neural circuits lend themselves more or less easily to different tought patterns. Basically, biopsychosocial.
