I've spent a solid 10 minutes following the rabbit hole of linked studies/papers and have not found any paper or study or figure that actually makes the "up to 10%" claim like the article says. I can't even find in any of the linked papers any sort of "1,500 person survey" like the article mentions. I started looking into it because of the weasel word "up to" in the title. "Up to" doesn't mean anything. 1% is "up to" 10%. 0.0001% is "up to" 10%. And what do you know? When I try to dive into an article with a weasel worded title to find the actual data they're referring to, it's nowhere to be found.
