Insufficient (or Incorrect) Data Leads to Inadequate Judgement

Though not entirely impossible, incorrect or insufficient data usually indicates that proper judgment cannot be exercised. In other words, attempting to solve for a given variable without having the appropriate numbers plugged into their various places in the equation being utilized means that an incorrect answer will almost always be the eventual result.

To further illustrate this concept, imagine if you will, using a broken calculator to compute any mathematical equation, from the meager total of a simple domestic shopping list all the way up to a crucial scientific formula in common use by NASA to safeguard the very lives of human astronauts being sent into Earth's orbit.

In other words, if the calculating machine being employed has even a single defective number key (which may be permanently depressed, or missing altogether, etc.), then the sum total of every possible equation will be incorrect each and every time that that particular device is used to "solve for X."

In fact, in many ways, the human mind is itself the most sophisticated "calculator," or organic computer rather, yet known to man. Therefore, if the mind of a specific individual is already damaged, or merely impaired in some fashion (great or small notwithstanding), then the flawed human being attempting to "judge," or solve for a given set of variables, will almost always, invariably, be wrong (to a greater or lesser extent) in their computations about, well, pretty much everything.

Or, as Matthew 7:1 (KJV) puts it, "Judge not, that ye be not judged."
