Perhaps the telling difference between psych-guy and me was that he said what he thought, or as he diagnosed himself, "sometimes I have trouble with impulse control".
Psych-guy's extreme helped me recognize that (a) too often I judged when no judgment was required, (b) too often my judgment proved to be wrong, and (c) too often I was inclined to stick with a wrong first impression.
Subsequently, by avoiding hasty conclusions I have more time to see and hear. If judgment eventually is required, I usually by then have better facts, and less bias to confirm a previous impression.
For example, there’s the matter of you. Yes, you there, reading this blog.
Probably it is safe to assume that if you have read this far that you are smarter, more spiritual, and altogether nicer than most people. Do I think you are needy, hurting, and anxious for the future? Many people are. But you might be the opposite, overconfident and presumptuous. I don't know.
By not prematurely judging, I have saved time and embarrassment. The trick is to use that time to hear, see, and serve.
“Stop judging by appearances. Judge by what is really right.” — John 7
"You will be judged in the same way that you judge others.” — Matthew 7
"Jesus entered Jericho and was passing through. A man was there by the name of Zacchaeus; he was a chief tax collector and was wealthy. He wanted to see who Jesus was, but being a short man he could not, because of the crowd. So he ran ahead and climbed a sycamore-fig tree to see him, since Jesus was coming that way. When Jesus reached the spot, he looked up and said to him, 'Zacchaeus, come down immediately. I must stay at your house today.' So he came down at once and welcomed him gladly. All the people saw this and began to mutter, 'He has gone to be the guest of a sinner.' But Zacchaeus stood up and said to the Lord, 'Look, Lord! Here and now I give half of my possessions to the poor, and if I have cheated anybody out of anything, I will pay back four times the amount.' Jesus said to him, 'Today salvation has come to this house, because this man, too, is a son of Abraham. For the Son of Man came to seek and to save what was lost.' — Luke 19
