I don't know anything about this particular one, but just because it's a case study in a textbook doesn't mean it's true. There are lots of untruths that get propagated long after they've been debunked.

But they’re citing a survey where people literally didn’t get it. That, if not made up, factually supports the claim that some people really do think 1/3 is less than 1/4.

I really liked the 1/3 pound “thickburgers”. I don’t think it was just some dying chain trying to spread rumors about how stupid people didn't understand their marketing and that’s why they “died” (they’re still very much alive last I checked).

> But they’re citing a survey

Then it should be possible to point to said survey…

If you had the survey in hand you could point to it. Proprietary information is not news and exists even in academia (cf. scihub).

Sure, but there's nothing presented to debunk this so far. So far all the "testimony" shows it to be true, but it could be propaganda.

The larger point is that it does demonstrate what the actual data shows - that the US has a sizable portion not good at math/fractions or finance.
