Seth Godin makes some interesting observations in his post on Rational vs Irrational decision making:

No one is rational all the time. In fact, somewhere along the way we made ‘irrational’ into a bad word, but it shouldn’t be.

If you’re running Adwords on Google, I hope you’re making rational decisions based on clickthrough and conversion… (But) Irrational passion is the key change agent of our economy. Faith and beauty and a desire to change things can’t be easily quantified, and we can’t live without them.

There’s room for both rational and irrational decision making, and I think we do best when we choose our path in advance instead of pretending to do one when we’re actually doing the other. The worst thing we can do is force one when we actually need the other.

I’ve seen this manifest countless times, and I couldn’t agree more.
