Seeing how my own posts are responded to here, I think Relevance is maybe a misnomer for Correct? I thought about this while reading the article, and was reminded of how a discussion I saw here recently played out.
from the article: The researchers targeted 2,000 Twitter users from a range of political persuasions who had tweeted 11 overtly false news articles. (Sample article topic: One time Donald Trump evicted a disabled veteran because of his therapy dog.) After an extremely polite correction in the thread, which included a link to factually accurate information, the tweeters’ accuracy declined further—and even more so when they were corrected by someone matching their political leanings. This indicates that partisanship is not driving the tweeters’ responses.
“We might have expected that being corrected would shift one’s attention to accuracy,” says coauthor David G. Rand, a professor at the MIT Sloan School of Management. But no! “Instead, it seems that getting publicly corrected by another user shifted people’s attention away from accuracy—perhaps to other social factors such as embarrassment.”
...in the meantime, Rand suggests that a “post about the importance of accuracy in general without debunking or attacking specific posts” may help focus friends on accuracy, and improve future posts.
