@natecull This reminds me. I was at a 2 day course in usability by Norman Nielsen Group.

They talked about they where frustrated that devs didn't take them seriously when the pointed out (via usability testing) that a UI was too difficult to use. The devs said "well the users are just not smart enough!".

To prove that the UI really was too difficult to use they did the usability test with rocket scientists from NASA and showed that even they couldn't figure out the UI.
