This isn't one of those silly Facebook quizzes, like the one that purports to tell you what voice part you should sing based on personality questions—the one that told me I should be singing low bass. It's from the Pew Research Center, and consists simply of 10 political statements for you to classify as factual or opinion. I thought they were all obvious and scored 5/5 on the factual statements and 5/5 on the opinion statements. Alas, the "nationally representative group of 5,035 randomly selected U.S. adults surveyed online between February 22 and March 4, 2018" did not do so well: only 26% had a perfect score on the factual part, and 35% on the opinion section.
If you take the quiz (which does not require an e-mail address, signing in, or anything else intrusive), you'll get to see not only your results but a breakdown of the people who answered each particular question correctly, based on political party affiliation and how much they trust national news organizations. The first is particularly interesting, if somewhat depressing. Unfortunately for partisans, there's no evidence that Democrats are smarter than Republicans, or vice versa. Sometimes one party fared better, sometimes the other. What is clear is that both parties have a strong tendency to label statements consonant with their own beliefs as fact, and statements that they disagree with as opinion. This despite the clear instructions:
Regardless of how knowledgeable you are about each topic, would you consider each statement to be a factual statement (whether you think it is accurate or not) or an opinion statement (whether you agree with it or not)?
What I find find disturbing is the apparently lack of understanding that a statement of fact can be wrong. "I have red hair" is a statement of fact—one that happens to be false. So is "I like to eat liver" (also false). The latter statement is factual, not opinion, even though it states my opinion of the taste of liver. "Liver is disgusting" is an opinion statement, and my agreeing with it does not make it factual.
It seems we have carried "I'm right, you're wrong" to a whole new level.
