But a growing field of professionals—from FBI interrogators to autism therapists—is learning to catch these involuntary "leakages" using a surprising piece of technology: the . micro expressions training tool

However, ethical concerns are mounting. Should a manager use METT skills during a termination meeting? Is it a violation of psychological privacy to “read” an involuntary facial tic? Several European privacy regulators have begun classifying advanced emotion-reading software as a form of biometric data, requiring explicit consent. Short answer: yes, but with realistic expectations. Several validated tools are available online. The official METT by Paul Ekman Group is the gold standard (paid, research-grade). Free alternatives exist in academic databases and some psychology apps, though they lack the progressive feedback loop. In the span of a heartbeat—literally 1/25th of

What results can you expect? Studies show that after 30 minutes with a METT, the average person improves from identifying 40% of micro expressions to over 80%. After a few hours, some trainees approach the ceiling of human ability—about 90-95% accuracy on standardized tests. Almost everyone does

Dr. Ekman’s breakthrough was identifying seven basic micro expressions (anger, fear, sadness, disgust, contempt, surprise, and happiness) and coding the specific muscle movements—via the Facial Action Coding System (FACS)—that create them.
