To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
I'm only about 20% through the book but I can already tell you 2 very important things. 1. The facts are interesting and for the most part appear to be accurate (I like to spot check). 2. It needed a much better editor/proof reader. The grammar is atrocious and some of it is very minor but completely breaks the flow. It makes it very difficult to enjoy when you're stumbling over sentences (we read these aloud on car trips). Also, I'm reading the kindle version so the print copy might be better.
