we must understand that there is a difference between good judgment and bad judgment. Bad judgments are meant to feed our own personal ego and put others feel worse
Judging quickly moves on to more intimate areas of your life. You start judging your close ones; friends, family members, partner, etc. You fail to appreciate them and start getting dissatisfied with them. You become critical of even those who matter to you.
If you judge people, sooner or later it becomes a habit, and you start judging everyone around you for the tiniest of things. You judge their clothing, actions, mannerisms, success, ambition, values, everything. And you might dismiss even the best of people through these microscopic judgments.
Researchers have found that a person's tendency to describe others in positive terms is an important indicator of his/her own personality. They discovered particularly strong associations between positively judging others, if you negatively judge other people, you are viewed negatively by people, in turn.
