At a conference this week I met this gentleman, an attorney who has studied physiognomy, or face reading, for over two decades. I knew I wouldn't have time to sit in on his presentation so I asked him to give me a 60-second sample by reading my face, and then I would buy his book.
He was right on some things, wrong on some others, so it was hard to tell how much of this is science and how much is hoo-hah. He sure nailed one thing, though, with this comment after about 45 seconds:
"You don't believe a word I'm saying to you right now, but you're listening very politely."
The book is interesting so far, and I can surely see the many practical uses if the accuracy is good.
