The New York times has an entertaining test to see if you can spot the liar. I got 8/10 correct and found it easier to guess after only watching the first few seconds of the video. I wanted to watch one video again, but I couldn’t. I’m guessing that’s intentional, so make sure to pay attention.
The article related to the test is about airline security’s misplaced faith in body language. After having just flown last week, I felt like the process wasn’t as bad. Maybe the TSA has come to terms with their role as security theater.
