In the Autumn semester, 1955, I taught Principles of Economics, and found it a challenge to convey basic microeconomic theory to students. Why/how co… - Vernon L. Smith

Nonsatiation (Smith, 1976a). Given a costless choice be ween two alternatives which differ only in that the first yields more of the reward medium (e.g., currency) than the second, the first will always be chosen (preferred) over the second by an autonomous individual, i.e., utility U(M) is a monotone increasing function of the reward medium.

When the theory performs well you also think, “Are there parallel results in naturally occurring field data?” You look for coherence across different data sets because theories are not specific to particular data sources. Such extensions are important because theories often make specific assumptions about information and institutions which can be controlled in the laboratory, but which may not accurately represent field data generating situations. Testing theories on the domain of their assumptions is sterile unless it is part of a research program concerned with extending the domain of applications of theory to field environments

I think it's different kinds of minds, and the recognition that certain mental deficiencies may actually have some selective advantages in terms of activities. We've lost a lot of the barriers that have to do with skin color and with various other characteristics. But there's still not sufficient recognition of mental diversities. And we don't all have to think alike to be communal and to live in a productive and satisfying world.
