So as an Undergrad Psych student, I took a class called Deception, Brain and Behavior with a noted expert in the field, Travis Seymour.
We went over the so called Micro-expression system developed by Paul Ekman, who helped create the TSA system, known as SPOT.
Some notes: Ekman's system depends on expressions occuring in 1/15th of a second. Trained observers who worked with Ekman for years still disagree on expressions, even when using slowed down film from high speed cameras.
And as best as I can find, the TSA does 7 days of training to use it, 4 in class and 3 on the job.
Oh and Ekman himself thinks the current SPOT system sucks, though that may just be covering his ass because he helped develop it.
Uh...don't you mean:25Wh / 50Wh = 2. Right?
26 minutes / 3 hours = roughly 1/6; 26 / 4 hours = roughly 1/8.
All seems condemned in the long run to approximate a state akin to Gaussian noise. -- James Martin
