Unfortunately I see the over application of this principle, and the general "Don't Make Me Think" approach all over the place. I build systems for people that use them all day long, every day. They become experts pretty quickly and start looking for shortcuts and other things, if you make them available to them. I have to deal with testers that assure me that if it doesn't make sense to them the first time, it's wrong. They even play dumb to make it harder on me. People can't even drive a car without training. We need to use progressive revelation of complexity and capability to make things more powerful. Using simplicity as the excuse to give up power- the "who needs a command prompt, everything can be done with a GUI approach" is often a mistake. Just because some people don't naturally understand something doesn't make it bad, you just have to teach them how to be more awesome, or let them stick with the defaults.
