I agree body language and handwriting “experts” always show way too much confidence in their diagnoses, but there are invariably some nuggets of truth.
I just wish they’d explain psychologically why a “bad” handshake feels so bad. And why there is agreement on what constitutes a “good” handshake. I had a co-worker would could not give a good handshake. He’d extend his hand and that’s it: there would be no grip pressure at all. I even tried to teach him how to do it. He really didn’t seem to understand the concept, and after 5-6 trials, he didn’t show much improvement. His job was to meet many different people a day, so a firm, confident handshake (or lack) would have certainly impacted his job performance.
