Thank you.

I think it's a poor mechanism because "appeared once in a pop magazine" isn't a good signal for knowledge curation regardless of whether you assign it a positive or negative weight; especially when the original comment implied (to my reading) "the topic has only surfaced once, therefore the existing knowledgebase is only one study."

The existence of a single study in pop literature is a very poor predictor of whether the study was accurate or not, and a very poor predictor of whether there are other studies on the topic. So I think it a mistake to substitute "it has come to my attention once" for "it has only been studied once."
