Why are there so many well-padded books out there that really ought to be nice, long articles? The subject came up over dinner the other night, and having just wrapped up a nice, long article, I think I may have an answer to this question: journalists, like many non-economists, do not properly understand sunk costs.

essentially all non-fiction books are still produced with the following characteristics:

• tons of filler material to reach a desired length
• give away most in the introduction
• assume readers are cognitively challenged

combine those things and you can get the gist of these books by using the free samples. enjoy!
