The part about non-voters was not supposed to be about facts, but about rationalizations. Whenever someone loses election, they can imagine that they would have won, if all the people would have voted.
Another popular rationalization, is that my side would have won if it wasn't for the biased media misinforming the public. I suppose that's also similar to CEV.
I have found this most wonderful (if fairly lengthy) article, and thought you would enjoy having it brought to your attention.
It is so good, I think we should include it among the references in the "Politics is the Mind Killer" wiki page. But, before that, I submit it to you, and ask you: is there anything in this article that would warrant its exclusion from this site? I mean, besides the fact that it is about politics, and written by a notorious Social-democrat (And is that in itself grounds for exclusion?).
