How to Be A Human Lie Detector is a course about – you guessed it – how to detect lies. This is done by learning how to notice microexpressions, body language, voice changes and even differences in the language employed when answering a question.
The course consists of a few hours of videos, plus a few downloadable PDFs. The videos are light and pleasant to watch, and fairly concise.
Overall, it took me about 4 hours, although I really think I should go through some of the critical videos again to actually learn the stuff beyond a basic level. Recommended if you are interested in the topic, but I'd wait for one of Udemy's coupons instead of paying full price.
