Munro cites an example from the previously mentioned textbook of forensic psychiatry (3). A 57-year-old former coal miner, referred to as Zhu, who had been an enthusiastic participant in Mao's Cultural Revolution, began to write extensively on political matters after he retired. He spoke to local political leaders and sent his writings to political journals, always signing his own name. His speech was logical, his behavior polite, and his lifestyle orderly. However, when subjected to psychiatric evaluation he was found to be suffering from paranoid psychosis on the basis that his theories were "conceptually chaotic" and in conflict with the principles laid down by the Central Committee. Moreover, "Zhu's views and utterances were incompatible with his status, position, qualifications, and learning; the great disparities here clearly demonstrated his divorcement from reality."
