Question

Think about the last person you met who gave you the impression that they weren't trustworthy. Assuming they weren't cackling maniacally, glancing around nervously, or straight-up telling you "You can't trust me," there was probably something in their voice that gave it away.

A simple hello is just enough to judge a person wheather he is trustworthy or not.

what is your opinion?

Answer 1

This is true that there exist a whole science and technology do understand motives of a person. A simple hello with voice has data as wide as tonal quality, tone range, emotional content, confidence, motive, volume, word gap, word flow , expectations,etc.

That said, so much depends upon context and our Brain takes about one-tenth of a second to judge people, irrespective of their true abilities. These sort of things are called Cognitive Biases.

I used to judge people, and hell did O suffered. If we want to influence people and get the best from them(oh ya, many wants that), it is best to put our judgment aside and really try to understand them. You will gain more because Social Skills are the No 1 skill for Quality Relationship ,which in itself is No 1 predictor of a GOOD LIFE.
