In 1946, a Macy Foundation interdisciplinary conference was organized to use the model provided by "feedback systems," honorifically referred to in earlier conferences as "teleological mechanisms," and later as "cybernetics," with the expectation that this model would provide a group of sciences with useful mathematical tools and, simultaneously, would serve as a form of cross-disciplinary communication. Out of the deliberations of this group came a whole series of fruitful developments of a very high order. Kurt Lewin (who died in 1947) took away from the first meeting the term "feedback". He suggested ways in which group processes, which he and his students were studying in a highly disciplined, rigorous way, could be improved by a "feedback process," as when, for example, a group was periodically given a report on the success or failure of its particular operations.

The differences between the two sexes is one of the important conditions upon which we have built the many varieties of human culture that give human beings dignity and stature.

I think it was my grandmother who gave me my ease in being a woman. She was unquestionably feminine — small and dainty and pretty and wholly without masculine protest or feminist aggrievement. She had gone to college when this was a very unusual thing for a girl to do, she had a very firm grasp of anything she paid attention to, she had married and had a child, and she a career of her own. All this was true of my mother as well. But my mother was filled with passionate resentment about the condition of women, as perhaps my grandmother might have been had my grandfather lived and had she borne five children and had little opportunity to use her special gifts and training. As it was, the two women I knew best were mothers and had professional training. So I had no reason to doubt that brains were suitable for a woman. And as I had my father's kind of mind — which was also his mother's — I learned that the mind is not sex-typed.
