Why Some People Notice Every Tiny Change

Why does one person notice a tiny change in someone's expression while another person sees nothing unusual? The answer may involve attention, experience, pattern recognition, and the brain's response to uncertainty. In this video, we unpack the psychology behind people who seem to read between the lines. We explain thin-slicing, examine what micro-expressions can and cannot tell us, and explore how hypervigilance can develop when a person's environment is unpredictable. Being observant can be valuable, but noticing a change is not the same as knowing its cause. A pause may be meaningful, or it may have an ordinary explanation. The goal is to understand the difference between intuition, evidence, and assumptions.
