When I began my study of Chinese Communist thought reform in the 1950s, the Western world had heard mostly about thought reform as applied in a military setting: the coerced bacteriological warfare confessions and the collaboration obtained from American (and other United Nations) prisoners during the Korean War. However, these were merely export versions of a thought reform program aimed not primarily at Westerners, but at the Chinese people themselves, and vigorously applied in universities, schools, special revolutionary collages, prisons, business and government offices, and labor and peasant organizations.
