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).
Ironically the study ignores the arguably most important part of facing fake news: being critical of sources. And as a reportedly “vulnerable” millennial myself, I have to say I’m critical of this one.
I agree, but they need to start someone. They’ll submit for review, get some errors pointed out there. Publish in a journal and get some more constructive criticism. The next study can learn from that to make improvements.
It’s already published in Behavior Research Methods. I might be too critical and focusing on the wrong things as a political scientist judging a psychology piece, but at least to me the test does not seem to be that convincing in measuring susceptibility to misinformation. The claim of the article (which I admittedly haven’t read carefully) seems to be that “it is feasible to develop a psychometrically validated measurement instrument for misinformation susceptibility”, which might still be the case.
