There is no evidence to suggest that Harry Stack Sullivan's concept of participant observation was influenced by quantum physics.
Harry Stack Sullivan was a psychiatrist and psychoanalyst who developed the theory of interpersonal relations. Sullivan believed that understanding human behavior required the observation of individuals within their social context, and he emphasized the importance of observing and participating in the social interactions of individuals in order to gain a deep understanding of their experiences.
Quantum physics, on the other hand, is a branch of physics that deals with the behavior of matter and energy at the atomic and subatomic level. It is concerned with the fundamental principles of nature and is not directly related to the study of human behavior.
While it is possible that Sullivan may have been familiar with some of the ideas of quantum physics, there is no evidence to suggest that his concept of participant observation was influenced by it. Sullivan's work was primarily influenced by the fields of psychology, psychiatry, and sociology, rather than physics.
