Out of the hundreds of examples that one might choose, take this question: Which of the three great allies, the U.S.S.R., Britain and the USA, has contributed most to the defeat of Germany?
I'm not convinced that question is even well defined. What does "contributed most" mean when mapped onto causality graphs?
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?).
