Say not "truth"

  1. "Different societies have different truths" – no, they have different beliefs
  2. A belief is not "true" when it matches reality – it is "pretty accurate". See also Examples of type error: a belief is a cons cell binding a proposition to a number between zero and one, never exactly zero and never exactly one, and certainly not a boolean. If your belief put 70% on something later shown real, the belief's accuracy was log2(70%) = -0.51 bits. If your belief put 30%, you did worse: log2(30%) = -1.73 bits. Accuracy is measured in negative numbers up to zero, never hitting exactly zero.
