Death, Tarot, Rorschach, scripts, and why economies crash

By Gordon Rugg

The best examples of powerful principles often come from unexpected places.

Today’s article is one of those cases. It’s about why it often makes excellent sense to use a particular method, even when you’re fully aware that the method doesn’t work as advertised on the box, or doesn’t work at all.

It’s a story that starts with one of the most widely misunderstood cards in the Tarot pack. The story also features some old friends, in the form of game theory, pattern matching and script theory. It ends, I hope, with a richer understanding of why human behaviour often makes much more sense when you look at the deep underlying regularities, rather than at the surface appearances.
