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.
The paper
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).
Just took a look here, and yeah. One of the headlines they ask you to rate is “Hyatt Will Remove Small Bottles from Hotel Bathrooms”. It’s the kind of thing that’s basically a coin flip. Without having any context into the story, I have no opinion on whether it’s fake or not. I don’t think guessing incorrectly on this one would indicate somebody is any more or less susceptible to miscategorizing stories as real/fake.
I assume the idea is to include some pointless headlines (such as this) in order to provide some sort of baseline. The researcher probably extracts several dimensions from the variables, and I assume this headline would feed into a “general scepticism” variable that measures he likelihood that the respondent will lean towards things being fake rather than real.
Still, I’m not at all convinced about this research design.
I suspect that where you select on the extremely liberal to extremely conservative spectrum might have a correlation to which fake news titles you fall for. What sounds like obvious propaganda to you may sound like any news article that some may see from a more sensationalist less reliable news source, especially to those predisposed to conspiracy theories.
