Dear FIS Colleagues, I hope that some of you, at least, are as interested as I am by the shift in topic from "Assymetry of Information" to "Information as Assymetry" that has taken place. As far as the latter is concerned, I now know much more about the contribution of Leyton and others, its historical development, etc.
However, despite some references to game theory and decision theory, I feel my orginal question, about differences of kind or "valence" of information has not been addressed. In real systems, especially social systems, much of the information transferred is not neutral, but comes in two main flavors, call them optimistic and pessimistic if you prefer. (Both are "real"; John Collier's questioning of the existence of "negative" information in his sense is appropriate). Perhaps this is a trivial distinction; perhaps its existence, and its consequences, are not. Thank you and best wishes, Joseph ----- Original Message ----- From: Robert Morris To: fis@listas.unizar.es Sent: Sunday, November 15, 2009 4:13 PM Subject: [Fis] Inventor of Information as Asymmetry It is absolutely the case that Michael Leyton invented the concept of information as asymmetry. Furthermore, David Weiss is correct: Leyton's work has been applied by scientists in over 40 disciplines. His theorems are used thousands of times, each moment of the day, all across the world. For example, Leyton's theorems are used in cardiac diagnosis, biomedical engineering, metereology, chemical engineering, mechanical aerospace design, geology, botany, etc. Richard Morris ------------------------------------------------------------------------------ _______________________________________________ fis mailing list fis@listas.unizar.es https://webmail.unizar.es/cgi-bin/mailman/listinfo/fis
