Complicated problems rarely require magical explanations

Our stroke medical professionals use the magical explanation and hand waving when they tell us 'All strokes are different, all stroke recoveries are different'. Another great post from Seth Godin, bet your doctor has never heard of him.

Complicated problems rarely require magical explanations 

The best paragraph.

Too often, the overly simplistic explanation is just a form of hand waving. We beg the question because we mention the simple explanation plus the miracle. It's the miracle, the homunculus, the little man in the machine, that actually holds the answer, and punting on explaining it is lazy. We use magic to kick the explanation down the road, making it not simple, but obtuse.
