#2: Excessive Blinking
Blink and you might miss it! If you notice someone blinking excessively after they’ve finished telling you something, it could be a sign that they’ve just told a lie. This phenomenon is known as “rebound blinking,” and it’s a common indicator of deception.
When we lie, our bodies often react in subtle ways that can give us away. Rebound blinking is one such way. It’s a natural response to the stress and discomfort that comes with telling a lie. Essentially, the liar blinks excessively after they’ve finished speaking as a way of relieving the tension and anxiety they’re feeling.
