This reminds of this article, Useless Medical Disclaimers. It&#x27;s about how medical disclaimers are useless because they don&#x27;t include probabilities, but they can&#x27;t because most people don&#x27;t understand probabilities: <a href="http:&#x2F;&#x2F;lesswrong.com&#x2F;lw&#x2F;h4&#x2F;useless_medical_disclaimers&#x2F;" rel="nofollow">http:&#x2F;&#x2F;lesswrong.com&#x2F;lw&#x2F;h4&#x2F;useless_medical_disclaimers&#x2F;</a><p>&gt;innumeracy being so widespread, no one would dare put numbers on that sheet of paper.  If &quot;amputation&quot; is listed as a consequence with a probability of 0.0001%, patients will run screaming out of the office, crying, &quot;Not my toe!  I don&#x27;t want to lose my toe!&quot;
