Once upon a time, my primary professional interest was in the psychology of deceiving and detecting deceit. I wrote about that in “My previous life as a deception researcher.” Now my passion is the study (and practice!) of single life. But I continue to get questions about deception. So I have compiled here many of my blog posts about lying and detecting lies. You can find many of these, plus some other writings, in the book, The Psychology of Lying and Detecting Lies. If you are interested in my other books about deception, you can find links here. (You may need to scroll down to find the books about deception.)
