Query: Marketing Propaganda

This book is nothing more than a marketing pamphlet for the author's services that cost an exorbitant amount of money. They repeatedly tell you how other forecasters and economists fail where they succeed. How other forecasters and economists continually suffer from "attribution bias" blaming their failures on uncontrollable events while taking full credit for their successes. However, they also attempt to explain away the failure of their indexes to successfully predict economic shifts, and therefore also suffer from attribution biases.
