What are the people who judges others too quickly missing out on?

What are the people who judges others too quickly missing out on? What I have in my mind right now is their chance of having a bigger network, so this means this person has this skill and the other has a different skill. They help each other and life is great. Another one is their chance of having more friends (networking too), and people will have bad impressions of the people who judges others too quickly without knowing them. So what else is there? Thank you so much for the people who answered this! I appreciate it. I really do. Thanks.
