Summary:
- This article discusses the psychological mechanism behind "thin-slicing," where human beings form rapid, intuitive judgments about a person's trustworthiness and competence within a fraction of a second (specifically 100 milliseconds) upon viewing a face.
- It highlights the evolutionary and social implications of these snap judgments, noting that while these impressions are formed almost instantaneously, they are remarkably consistent across different observers, even if they do not necessarily reflect the true character of the individual being observed.
