Just Finsihed Reading: "Fooled by Randomness" #books
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.
