From my “Murphy’s Law” desk calendar archives thanks to Aunt Evelyn, Uncle Pipey, and cousin Nancy:
Christie-Davies Therom: If your facts are wrong but your logic is perfect, then your conclusions are inevitably false. Therefore, by making mistakes in your logic, you have at lease a random chance of coming to a correct conclusion.
Goofy guy’s admonition concerning the Christie-Cavies Theorum: This does not apply to politicians. There is no random chance there will be a correct conclusion.
