Well, my point in response to your point is that Google turns up no hits on “studies show that you use 10% of your brain”, so you didn’t actually pick a real-world example to illustrate the concept “real-world example”. I’m sure someone has said this, at some point or other, but you didn’t show a real-world example of it.
And my more general thesis, applied to your valid example, is not that: When people say “studies show”, there often isn’t any actual study. But that: Even when the studies are real, “studies show” doesn’t tell you anything about them.
