Help finding a picture

Question

Blogs

About a year ago I saw a picture with a graph (something like a logarithm). There were 2 curves on it, one depicted real knowledge, the second something like "self-confidence".
A la "the more I know the less I know."
I've searched all over the internet and can't find it.
Help me find someone who remembers. I have karma and hundreds of oil. Thank you in advance.

PS Don't even ask why I won't draw it myself, I need it.
