Dan Ariely wonders why we accept our physical limitations but don't want to account for our cognitive ones:
Imagine that you’re in charge of designing highways, and you plan them under the assumption that all people drive perfectly. What would such rational road designs look like? Certainly, there would be no paved margins on the side of the road. Why would we lay concrete and asphalt on a part of the road where no one is supposed to drive on? Second, we would not have cut lines on the side of the road that make a brrrrrr sound when you drive over them, because all people are expected to drive perfectly straight down the middle of the lane. ...
What I find amazing is that when it comes to designing the mental and cognitive realm, we somehow assume that human beings are without bounds.
