Not really an opinion, but either a conjecture or a belief about a question of fact. It may not be easy to determine whether the conjecture is true or not, but it's still a question of fact and not just an opinion. > I don't think it matches reality. That it is reasonable to ask whether the statement matches reality is a giveaway that the proposition is a question of fact and not merely a matter of opinion.
