Is there a way to determine if a statement is a statement that can be right or wrong and not a statement that has pros and cons to it?

Let me try and explain that more.

So maybe a statement like “America is a force for good” could have pros going and cons agreeing with that statement and not.

“Do we have free will” is that a statement that we could say is either right or wrong or can we never say this about statement for certain?

If so how can we know if a statement is one of the two as in either true or not or has pros and cons?
