If you live in an urban area, you probably don’t need to walk very far to find a martial arts dojo.

Why aren’t there dojos that teach rationality?

Very recently—in just the last few decades—the human species has acquired a great deal of new knowledge about human rationality. Experimental investigations of empirical human psychology; and theoretical probability theory to interpret what our experiments tell us; and evolutionary theory to explain the conclusions.

These fields give us new focusing lenses through which to view the landscape of our own minds. We have a shared vocabulary in which to describe problems and solutions.

Humanity may finally be ready to synthesize the martial art of mind: to refine, share, systematize, and pass on techniques of personal rationality.
