I'm not sure this is a good study. I mean I scored 85% so woohoo but you just get headlines to go off. The art of noticing disinformation is in reading articles and making inferences on them. Questions like "vaccines contain harmful chemicals" are obvious red flags but there are some that are a reasonable-sounding headline but I'd imagine the article itself would fall apart on first reading. I know half the problem is people don't read articles but this is a very simplistic survey.
