I heard a statistic today

I heard a statistic today that read: 83% of all statistics are made up on the spot, and 43% of the true statistics are in error.

How can anyone trust a statistic? So 17% of the statistics you hear are based on facts, but 43% of those are still in error.  This suggesting, if you hear 100 statistics a week, 83 were made up, and 17 were based in fact.   Of those 17, roughly half, 43% are in error. Leaving you with 8 that you can somewhat put faith into.   Trouble is, out of the hundred you hear, which 8 should you trust? lol
