"It might have been necessary a decade ago to argue for the commonality of the information processes that are employed by such disparate systems as computers and human nervous systems. The evidence for that commonality is now overwhelming." (Simon, 1980)


Herb Simon's list of talents have contributed to a wide range of academic, commercial, and research institutions. He is best known for his work with Alan Newell in the design of the "information processing" model of human cognition. Their book Human Problem Solving was a landmark in rethinking how the brain functions and also provided pathways toward Artificial Intelligence theory and Cognitive Psychology. The basic premise breaks down human cognition into components that are guided by symbol systems. Here's a good primer in their general theory of intelligence.

Simon's earlier work focused on human decision making, an account for why human's behave in not always optimum manner called bounded rationality. His theory of decisions underscores the limited capacity of human processing systems, reflected in the observed pattern of least best decision choices. Hence, Simon's interest and influence in public administration, and administrative organizations. It was for this work that he won the Nobel Prize.

Simon is also noted for his Artificial Intelligence work, and EPAM theory of human perception and memory. His work with Newell was pioneering in the use of computer simulation to map human behavior. In computers, Simon has found a tool that can closely model and record problem solving techniques. This is critical to HCI, in that we can rethink computers and people, using these theories, as different instantiations, of the same system.
