Some of these essays are about competitive strategy and strategic thinking; some are not. “Are Capitalists Copping Out?” “We Will Play Soothing, Uninterrupted Music While You Wait.” “The Formerly United States of America.” And more.

No one — well, no human — says a rat is smarter than a human; yet, in an experiment, rat beats human. Why? How? The rat isn’t doing anything a human can’t. The rat is doing something a human won’t.

Death by Shark

Your odds of dying as the result of an unprovoked shark attack are roughly 1 in 300,000,000 in the USA. The odds are more than 20 times higher in Australia.

All About Models

We can classify models chemically: those based on carbon and those based on silicon. The former, mental models, operate inside our heads. The latter, computer-based models, operate inside computers. They behave differently. (#1 in a series)
