It's very en vogue for young, analytical types to pretend we're hyper-rational and insist we should all act according to that assumption, but the reality is that none of us are hyper-rational, much as we like to imagine ourselves that way. THe way to deal with our limited rationality is not to say "well, you should start being hyper-rational" and organize our environment as if that will work. It's to acknowledge your limitations and organize your environment in ways that accommodates your limited rationality.
