Yes, this exactly. Donald Rumsfeld got no end of flack for his comment (distilled here) "there are known knowns, known unknowns, and unknown unknowns", but it's actually a great statement - in this case, there are some people who know they know how to make captchas, some people who know they don't, and some people who don't know that they don't know. |
