Sometimes it’s much easier to write 1,000 words on a topic than to write 10. As Mark Twain writes, “I didn’t have time to write a short letter, so I wrote a long one instead.”

Or as Arnold Kling writes, “When I finish writing a book review, I will often say to myself, ‘There! Now nobody has to read the book. I’ve boiled it down for them.’ We would be better off if authors did that work themselves.”
