The basic concept is set in 20 pages. The remainder of the book is applying them ,in detail, to a variety of situations. This could be interesting, but the application in each case is exactly the same. Once you understand the concept, you can make the same application yourself.The small amount of research cited is quite interesting, but the rest of the book is tedious and repetitive. This would be a great book to borrow from the library as opposed to buying.
