Be approximately right

Far better an approximate answer to the right question, which is often vague, than an exact answer to the wrong question, which can always be made precise.

— John W Turkey

Consider the value of an answer along 2 axes: accuracy and precision.

  • High accuracy, low precision — "Pi is 3.14"
  • High precision, low accuracy — "Pi is 5.230394891123039491203157"
