A closer look
The concept of the human lie detector is mostly Hollywood fantasy. Microexpressions—fleeting, involuntary facial spasms that allegedly reveal true emotions—are incredibly real, but our ability to interpret them is fundamentally flawed. Recognition bias ensures we project our own prejudices onto others. If someone is naturally anxious or just has an aggressive resting face, observers will confidently misinterpret their physiological baseline as malicious deception. We arrogantly believe we can read minds through muscle twitches, when we're actually just reacting to our own stereotypes.
