1000 is extremely conservative. Every time you play any game with an element of chance - risk, backgammon, poker, scrabble, blackjack, or even just flipping a coin - the odds against you getting the exact sequence of outcomes you do get will be astronomical. So the limiting factor on how many unbelievable outcomes you perceive in a lifetime is how good you are at recognizing patterns as "unusual". Somebody who studied numerology or had "lucky numbers" or paid attention to "lucky streaks" would see them all the time.
In the case at hand, that same series of rolls would be just as unlikely if it had happened at the beginning of the game or in the middle or spread throughout the match and hadn't determined the outcome. Unless there was something special about this particular game that made its outcome matter - perhaps it was being televised, there was a million dollars bet on it, or it was otherwise your last chance to achieve some important outcome - the main thing that makes that sequence of rolls more noteworthy than any other sequence of rolls of equivalent length is selection bias, not degree of unlikeliness.
"the odds against you getting the exact sequence of outcomes you do get will be astronomical"
People notice and remember things they care about. Usually people care whether they win or lose, not the exact sequence of moves that produced the result. For an event to register as unusual a person must care about the outcome and recognize that the outcome is rare. The Risk game was special because I cared enough about the outcome to notice that I was losing, because the outcome (of losing) with 26 vs. 1 armies was incredibly unlikely, and because I could calculate the odds against such an outcome occurring due to chance.
What do you believe that most people on this site don't?
I'm especially looking for things that you wouldn't even mention if someone wasn't explicitly asking for them. Stuff you're not even comfortable writing under your own name. Making a one-shot account here is very easy, go ahead and do that if you don't want to tarnish your image.
I think a big problem with a "community" dedicated to being less wrong is that it will make people more concerned about APPEARING less wrong. The biggest part of my intellectual journey so far has been the acquisition of new and startling knowledge, and that knowledge doesn't seem likely to turn up here in the conditions that currently exist.
So please, tell me the crazy things you're otherwise afraid to say. I want to know them, because they might be true.
