Tangentially, some years ago I recall reading a few articles about the problem with 'misconception busting' articles [I may try to find such an article later]. Apparently, content formatted like...

> Myth: Spinach has a high iron content

> Fact: Spinach does not have a particularly high iron content

... actually tends to reinforce the misconception in readers.

This suggests to me that similar fact-checking content is inherently harmful for their achieving their intended purpose.
