Big pharma is needed to create the catalyst agent for the mind hack. Psych meds such as SSRI's regulate and change the brains neurotransmitters- serotonin, dopamine etc. The proper amount and ratio of these n/t are needed for optimal mental stability. When altered the subject behaves differently. These are known as chemical imbalances. Patients may then be able to be manipulated through the power of suggestion. Schitzophrenics often present with paranoid dilusion about demons and govt control. In my opinion these people would be very suceptible to subtle suggestive thought control.
