How to determine if a person's cognitive level is above yours? First, sometimes when you haven't finished speaking or even haven't organized your thoughts, they can understand your meaning. Second, they agree with what you say but always provide a different perspective; they would never dismiss you outright just because you are wrong. Third, they don't use complicated language; no matter how complex the situation, they can explain it to you in the simplest words so you understand immediately. Fourth, it's always very comfortable to be around them. Despite their extensive knowledge, they are always able to be inclusive and adaptable.
