The Macy Conferences were a set of meetings of scholars from various disciplines held in New York by the initiative of Warren McCulloch and the Macy Foundation from 1946 to 1953. The principal purpose of these series of conferences was to set the foundations for a general science of the workings of the human mind.^[1]

It was one of the first organized studies of interdisciplinarity, spawning breakthroughs in systems theory, cybernetics, and what later became known as cognitive science.

[edit] Overview

The Macy Conferences were organised by the Josiah Macy, Jr. Foundation, motivated by Lawrence K. Frank and Frank Fremont-Smith of the Macy Foundation.^[2] The participants were leading scientists from a wide range of fields. Casual recollections of several participants stress the communicative difficulties in the beginning, giving way to the gradual establishment of a common language powerful enough to communicate the intricacies of the various fields of expertise present.

The scientists participating in all or most of the conferences are known as the "core group." They include:^[3]

• William Ross Ashby; psychiatrist
• Gregory Bateson; anthropologist
• Julian Bigelow; electro technician
• Heinz von Foerster; biophysicist
• Lawrence K. Frank; social scientist
• Ralph W. Gerard; neurophysiologist
• Molly Harrower; psychologist
• Lawrence Kubie; psychatrist
• Paul Lazarsfeld; sociologist
• Kurt Lewin; psychologist
• Warren McCulloch (chair); psychatrist
• Margaret Mead; anthropologist
• John von Neumann; mathematician
• Walter Pitts; mathematician
• Arturo Rosenblueth; physiologist
• Leonard J. Savage; mathematician
• Norbert Wiener; mathematician

In addition to the core group several invited guests participated in the conferences. Amongst many others:

• Max Delbrück; geneticist and biophysicist
• Erik Erikson; psychologist
• Claude Shannon; information theorist
• Talcott Parsons; sociologist.

Some of the researchers present at the conferences later went on to do extensive government funded research on the psychological effects of LSD, and its potential as a tool for interrogation and psychological manipulation in such projects as the CIA's MKULTRA program.^[4]
