TOPIC: Stupidity.

This week, Dan and Merlin tackle stupidity. And, brother, there sure are a whole lot of flavors of stupid.

Are we really talking about being clueless, unaware, dumb, absent-minded, or just plain-old ignorant? Because they're actually pretty different animals.

Whether you're dropping your library book in the mailbox, leaving your iPad at home, following baseless medical advice, or doing whatever Dan did with his garage door (don't worry: the car is fine), it's really helpful to understand where your real problem really lives.

From a tactical standpoint, try some useful failsafes, rituals, and habits. But, at a higher level, learn to develop the curiosity to keep evolving. Stay open to how you might be wrong by always seeking out the smartest person you can find who disagrees with you.
