The neuroscience-based literal cures for bullshit are the following:

1) temporal reduction of serotoninergic transmission in the right hemisphere of the human brain; 2) caloric vestibular stimulation (of the left ear);

all of which are supposed to induce some critical thought. Caloric vestibular stimulation is basically pouring cold water into the left ear, which is supposed to induce a specific pattern of activity in the right hemisphere, which have been shown to reverse pattern non-recognition.

Why can't psychiatrists prescribe those treatments for politicians etc? Because psychiatry itself is a bullshit medicine.
