Our thoughts and mental models determine how we see the world, so as change investors, we like to make sure we have a few different ways of seeing. It's one of the neatest things humans can do -- intelligence plus empathy = vast possibilities. We use change frameworks to do this, and today, I suppose we’re introducing a new change framework. I found this one in the work of Robert A. Johnson, so it comes from a mix of psychology and medieval religion, a combination I never thought I’d attend to as an investor, but it helped me think of marketplace changes in a very new way, so I hope you find it useful too.
