I really dislike "The Sequences: How to become Less Wrong." The problem I have with it is that I think it misrepresents what one of titular sequences actually is. The impression I receive is that this book offers some step by step instructions, known as the Mysterious and Capitalized "Sequences" that will improve your life and make you a better person.

...ok so maybe it's not that far off but the point I'm trying to make here is: A book that advertises itself that way doesn't sound legitimate. It gives me an impression of belonging to the "self-help book" category, which has a fairly bad reputation. If I saw a book with that title in a book store, I'd probably smirk at it and move on. Whereas I think that beginning the title with "Rationality" gives it a more scientific air. And I ah e to imagine that the idea here is that the cover of the book should reflect the contents as usefully as possible.
