       | If you take the example of Treatment A vs Treatment B for tumors,
       | you can get infinite layers of seemingly contradicting statemens:
       | - Overall, Treatment A has better average results - But if you
       | add tumor size, Treatment B is always better - But if you add
       | gender to size, Treatment B is always better - But if you add age
       | category to gender and size, Treatment A is always better -
       | etc...
       | 
       | It totally contradicts our instincts, and shows statistics can be
       | profoundly misleading (intentionally or not).
