I'm not sure how to parse "name a contradiction" as if they come in different types.

Perhaps you are not sure what I mean by "contradiction"?

A contradiction is a deviation from whatever someone sees, observes, or measures as "true", consistent or predictable,which is the opposite of contradictory. T and F.

False is contradictory to that which is true.

Communication that is honest simply produces less contradictions than communication that is dishonest.

A contradiction is not a "mistake", a contradiction may only reveal a mistake, or a deception, or a delusion, or a manipulation.

Deception produces contradictions to whatever the honest view is.

Delusion produces contradictions to whatever viewpoint clarity has.

What is there to disagree with?

You say "I don't trust the mainstream narrative!" and I bet you do trust the mainstream narrative on many many many things, just not the things you believe are true.

So I predict you likely made a contradiction there.

So you see a "contradiction" in the mainstream as opposed to whatever it is you believe.

Lawyers, journalists, mathematicians, and all accountants all use "contradictions" to measure the truth values they publish.
