The module was concise, intense, and packed with valuable insights. As someone who is deeply interested in body language, I found that this course added an important new dimension by emphasising the power of listening with intent. It has definitely enhanced my understanding of advanced lie detection techniques.

By David Tillman on 2/14/2025

Experienced and informative. Strong outlines of counters to lying and creates a useful framework for evaluating a lie step by step in a conversation, up to getting a confession. User should be mindful this framework he teaches is scalable and not applicable to all situations, but it is very good for HR or investigative roles. Some tactics could be used interpersonally, but the whole framework may not apply in those cases.

By Kathleen Zimmerman on 2/6/2024

I really enjoyed this course and can see utilizing some of the things I learned in my life, but when I took notes using the outline, the lecture did not seem to follow the outline. I took notes on what he said he was going to talk about, but after that, he repeated the topic and gave new information. It was a little confusing.

By Cynthia Whitediemand on 12/28/2022

For me it has been an excellent quick and to the point course which fit into the timeline I had for it. He provides excellent examples for the lessons he is teaching. There are not practice sessions, but that is okay, this course isn't designed for that. There are longer courses available that would provide those types of lessons for those interested in continuing in this field. I have taken other body language courses and have read Body Language books and felt fairly confident in my studies, but recently came into contact with a couple of people that will now forever be a part of my life, and who I know have habits of lying. It is less a question of "if" and more a question of "when." This course helped reinforce my confidence so that when I converse with these people, I will have a better radar for their lies. As I will only interact with these people once in a while every other month or so, I know I will review the material in this course before those interactions in order to keep my guard up and my skills sharp.

As a member of the security and intelligence forces in my country, I was intriuged at what I can learn from this course. As expected, It is a basic course, easily approachable by anyone, and can be used in our daily lives. I wasnt expecting to learn anything new, but to reaffirm what I know, but did. As for the technical aspect, this course is clear, simple and to the point, well constructed and well handed to the students. Highly recommended to anyone.

By Robert Howard Bosworth on 12/27/2020

Very informative!

By Robert C. Smith on 12/27/2020

These are approaches that I may, or may not have used in the past, but they seem familiar. I may have used them, or had them used on me but hearing them "formalized" seems to add to their validity. Fun! Undoubtably I will refer this course to (vulnerable) friends to hopefully tilt life's balance their way.

By Leah Martinez on 12/27/2020

The approach is ingenious -- I love it.

By Krystian Pleskacewicz on 12/27/2020

An interesting insight into the behaviour of people that lie with clear tips on what to look for.

By Melanie Gendron on 12/20/2020

Clear, complete and interesting courses.

By Elias Espinoza on 11/27/2020

Awesome!. No one will lie to me again.

By Michael Cook on 11/25/2020

Very power class
