let me pose the question in a manner reddit can understand.  > you have a giant bag filled with 6 million balls that are identical in every way except some are gold and some are silver. i blindfold you and you start drawing balls from the bag. after you have randomly drawn 4.3 million balls 57% are gold and 42% are silver. i tell you we're going to take a break, then the next morning i tell you i pulled the rest of the balls and it turns out there were more silver ones in total. we do this 5 more times. now in a logically consistent manner tell me why pre-election polls with much smaller samples (often biased) are any use at all and a billion dollar industry.
