A New Thought in the Endless Discussion

Speaking to Robert on the phone tonight, I thought of a new characterization of the difference between psychology and economics:

Psychology studies real people in fake situations.

Economics studies fake people in real situations.

It's interesting to wonder where these disciplines will be in 50 years or so and what debates, controversies, and criticisms we will be talking about in our wheelchairs. (In 50 years, will we have flying wheelchairs? That would be sweet.)
