About a third of 18- to 49-year-olds (32%) correctly identified all five of the factual statements as factual, compared with two-in-ten among those ages 50 and older. A similar pattern emerges for the opinion statements. Among 18- to 49-year-olds, 44% correctly identified all five opinion statements as opinions, compared with 26% among those ages 50 and older.
I find this a bit weird, because knowing a fact from an opinion is quite a basic and fundamental concept that was drilled into us at school. Perhaps older generations were not taught this. That would certainly explain a few things.
