From Andrew Sobel: A large body of research shows that when we meet someone for the first time, we make judg­ments about their trust­wor­thi­ness and compe­tence in a frac­tion of a second. We do this based on a variety of clues, including phys­ical appear­ance, facial char­ac­ter­is­tics, posture, gestures, and so on.  This makes sense from an evolu­tionary perspec­tive. When you meet a stranger, you need to assess their inten­tions (trust­wor­thi­ness) and their ability to carry out those inten­tions (compe­tence, or strength). · Go to Should you trust first impres­sions? →
