Often paraphrased: "Learning is not compulsory. Neither is survival."

Frequently attributed to Deming, probably through Mary Walton, The Deming Management Method, ch. 20 (1986), though it is presented there without attribution: "'In God we trust. All others must bring data.' If there is a credo for statisticians, it is that."

Fisher, Effect of Smoking on Nonsmokers: Hearing Before the Subcommittee on Tobacco of the Committee on Agriculture, House of Representatives, Ninety-fifth Congress, Second Session (7 Sep 1978): "I should like to close by citing a well-recognized cliche in scientific circles. The cliche is, 'In God we trust, others must provide data.'"

The supposition is prevalent the world over that there would be no problems in production or service if only our production workers would do their jobs in the way that they were taught. Pleasant dreams. The workers are handicapped by the system, and the system belongs to the management.

A system must be managed. It will not manage itself. Left to themselves in the Western world, components become selfish, competitive, independent profit centres, and thus destroy the system. The secret is cooperation between components toward the aim of the organization. We can not afford the destructive effect of competition.
