I found the linked paradoxes on the Wikipedia article more interesting: http://en.wikipedia.org/wiki/Simpson%27s_paradox http://en.wikipedia.org/wiki/Simpson%27s_paradox and http://en.wikipedia.org/wiki/Braess_paradox http://en.wikipedia.org/wiki/Braess_paradox And the discussion on whether it can rightfully be called a paradox: "it was debated whether the word 'paradox' is an appropriate description given that the Parrondo effect can be understood in mathematical terms" the funny counterpoint: "Is Parrondo's paradox really a "paradox"? This question is sometimes asked by mathematicians, whereas physicists usually don't worry about such things." This is a case of http://xkcd.com/214/ http://xkcd.com/214/ :)
