For Christmas my girlfriend’s mother followed the advise I long ago gave to my girlfriend: “Only buy a book for when you don’t understand what it says on the cover.” That resulted in the book Fooled by Randomness by Nassim Nicholas Taleb. It covers a number of points, one of which is excellently explained in the Dilbert strip below:
One of the point that Taleb makes is one that Bruce Schneier also makes: the difficulty for people to understand causality and correlation. It is such a difficult subject that even Taleb confuses correlation with causality when it comes to smoking, for which I assume he has a distaste, and this exactly proves the point that his book is making.
“The whole system is designed to catch stupid terrorists,” Schneier told me. A smart terrorist, he says, won’t try to bring a knife aboard a plane, as I had been doing; he’ll make his own, in the airplane bathroom. Schneier told me the recipe: “Get some steel epoxy glue at a hardware store. It comes in two tubes, one with steel dust and then a hardener. You make the mold by folding a piece of cardboard in two, and then you mix the two tubes together. You can use a metal spoon for the handle. It hardens in 15 minutes.”
