I think that can vary from person to person.
My previous self would say that it's impossible to not judge things in such manner. But, in recent times I've been experimenting with and exploring the concept of non-judgment and trying to understand it better and the popular argument I've heard is that people try to use the word "observe" instead and in a neutral manner to sort of expand the possibilities involved instead of to narrow the possibilities.

If you can theoretically observe without judging you leave room for more growth and learning instead of sort of "cementing in stone" a given subject or idea.

If you believe something is 100% the truth you eliminate all other possibilities and I am trying to keep my mind open to the possibilities.
