Title: A very misleading book
Product review: Dr. Lykken contradicts himself through out the book. How can you say the polygraph doesn't work, and then promote the GKT for the detection of truth? His work research is indirect conflict with and has been discredited by other researcher such as Rakins, Honts, Kirscher and Abrams (and many others). Interestingly, since he first wrote this book, the Guilty Knowledge Test has been almost universally accepted as being worthless and little better than a coin toss.
Would you say this review depicts the product in a flattering or unflattering light?
