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 analyses reviews to verify trustworthiness.
BOOK IS EASY TO READ & FOLLOW. THE AUTHOR GOES INTO DETAIL IN EXPLAINING HIS TECHNIQUES. THE AUTHOR WILL DISCUSS ACTUAL CASES FREQUENTLY IN EACH CHAPTER. IN EACH CHAPTER HE WILL HIGHLIGHT SPECIFIC PARTS OF AN INTERVIEW, THAT PERTAIN TO THE CHAPTER YOU ARE READING. AS A GANG INVESTIGATOR, I FOUND THE INFORMATION USEFUL, & EAGER TO APPLY IN SUBSEQUENT INTERVIEWS.
This book is a good read. Sometimes his deception detection signs seem a little bit too definitive, but I do appreciate that most of the time, the author classifies them as "signs", and not absolute evidence of deception. It is very informative!
