Maybe you don't understand what the equation says.  Maybe you understand it in theory, but every time you try to apply it in practice you get mixed up trying to remember the difference between p(a|x) and p(x|a), and whether p(a)*p(x|a) belongs in the numerator or the denominator.  Maybe you see the theorem, and you understand the theorem, and you can use the theorem, but you can't understand why your friends and/or research colleagues seem to think it's the secret of the universe.  Maybe your friends are all wearing Bayes' Theorem T-shirts, and you're feeling left out.  Maybe you're a girl looking for a boyfriend, but the boy you're interested in refuses to date anyone who "isn't Bayesian".  What matters is that Bayes is cool, and if you don't know Bayes, you aren't cool.

So how has the influx of new users changed the ways in which Twitter is used?

This book is as vital today as it was when it was first published in 1954. An invaluable exploration of grossly distorted graphs, correlation/causation confusion, and sucky sampling.

The Misconception: You take randomness into account when determining cause and effect.

"Six months has passed since I chewed out 20 revised social media stats, so I went back to see if there were any more changes. It turns out that there were, so I’m updating some of the more impressive ones..."

Last season, in a bid to draw some attention to Battier’s defense, the Rockets’ public-relations department would send a staff member to the opponent’s locker room to ask leading questions of whichever superstar Battier had just hamstrung: “Why did you have so much trouble tonight?” “Did he do something to disrupt your game?” According to Battier: “They usually say they had an off night.

"The Metropolitan Club, on Fifth Avenue at 60th street, is a palazzo in the mighty Manhattan style. Damn the expense. That’s what J.P. Morgan is supposed to have said when he commissioned Stanford White, the city’s most flamboyant architect, to build him a private gentleman’s club in 1894. Inside, on a Monday evening in late January, only a few members drifted over the red, monogrammed carpets, but it was still early, only a little after seven.
