University of Cambridge psychologists have developed the first validated "misinformation susceptibility test": a quick two-minute quiz that gives a solid indication of how vulnerable a person is to being duped by the kind of fabricated news that floods online spaces.
Researchers want the public to test themselves: https://yourmist.streamlit.app/. Selecting true or false against 20 headlines gives the user a set of scores and a "resilience" ranking that compares them to the wider U.S. population. It takes less than two minutes to complete.
Edit: the article might be misrepresenting the study and its findings, so it's worth checking the paper itself. (See @realChem 's comment in the thread).
I recall reading something about fake news and propaganda some decades ago. Can't recall the source book but it goes like this:
If one person tells you something absolutely outrageous you won't believe it. If a second person tells you the same story you will stop and wonder. If a third person, preferably someone you respect, tells you the same you will have no doubts about the story at all.
I have no idea how true this is but if two more people tell you the same thing...
That's... That was true for me, I think. I'm old, didn't always have the internet, I trusted books and family.
But I trusted books, which made me a bit of an alien in my family. And then I acquired extreme suspicion of everything when, at the same time, I started paying attention to far-right politics, and my family got sucked into far-right thinking.
Now they went full Qanon, which pretty much radicalized me. Things are so emotionally charged for me now that I have to doubt and cross-check out of sheer and absolute spite. That shit robbed me of my family and I am so, so pissed.
I have no idea how true this [the saying] is but if two more people tell you the same thing…
I'm not sure, but I think that this is largerly true to the masses because we [people in general] are not well trained to think rationally on the matters, so we let fallacies like ad populum stain our beliefs.
Critical thinking is not just something that you use "when you science"; it's something for your whole life. It makes you a better human being, as you understand better the world and people around you. And it would make people extra resilient against misinformation.
