@Jeff,
"I'll repeat: Just by adding "It's my opinion that.." or "I believe that..." does NOT turn a fact into an opinion. Rather, the inverse is true."
I'm not sure who claimed that adding words to something changed one thing into another. Certainly not the author or me. You may be tilting at a straw man here.
"If you can take away "It's my opinion that..." or "I believe that..." from a sentence, you eliminate unnecessary words and get to the point of the matter."
Of course. This is a point about good writing, though. It has precisely nothing to do with what is fact and what is opinion.
"What remains is a statement of fact. That statement may be true or false, but it is a statement nonetheless."
What remains is an *assertion* of fact, i.e., an opinion as to the factuality of the thing asserted.
"This is also what the CCSS is trying to demonstrate."
No. On your classification, the CCSS would have categorized everything as a "fact."
""Your "belief" that you have brown hair or "belief" that your car runs on gasoline has *absolutely* nothing to do with the truth of the matter."
Well, I agree, if I interpret you correctly, and in fact, the author said as much. If my hair is brown, it's not brown because I believe it. However, my belief may be based on good reason, in which case the fact does have something to do with my belief.
In either event, the fact is an objective feature of the world. What I express when I say "My hair is brown" is a belief as to that fact.
"Those facts can be objectively determined outside any human judgment."
Hardly. The judgment involved is based on extremely sure footing -- our senses, reading (with our senses) scientific instruments, etc. -- but nevertheless judgment is involved. If you'd said, "Those facts objectively exist without any human judgment," I would agree -- but the words "can be determined" kind of kill it.
In any event, here is the distinction: the brownness of my hair is an objective fact about the world. It is there irrespective of any beliefs about it. But the mental state, in my head, wherein I believe (or know) my hair to be brown is a belief -- a very highly rationally supported one, in this case.
"Think of how the CCSS would be used in a mock trial. Facts are indisputable bits of evidence. Opinions are beliefs about what happened outside the facts. Reasoned judgment is the intersection of the two where the facts and evidence provide the ability to infer outcomes or behavior."
"It really is that straightforward."
And it's a straightforward misuse of terminology.
Facts are not "indisputable bits of evidence." Facts are the truths that the jury is trying to discover, and evidence, both indisputable and otherwise, constitutes some of the grounding by which they attempt to come to correct beliefs about those facts. And yes, I've participated in mock trials. Conflating evidence and facts is an absolutely elementary error.
