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).
It is, and I feel the questions are quite obvious.
That being said… I’m related to conspiracy theorists. I got a first-row seat to their dumbassery on facebook before I deleted my account. And… a significant issue was paywalled articles with clickbait titles, during Covid especially. The title was a doubt-inducing questions, such as “Do vaccines make you magnetic?” and the reasoning disproving that was locked behind the paywall. And my relatives used those as confirmation that their views were true. Because the headlines introduced doubt and the content wasn’t readable. That and satire articles.
