NASA has been using PCM (Process Communication Model®) for the selection and training of astronauts since 1978. Dr. Terry McGuire, the consulting psychiatrist at NASA, responsible for astronaut crew selection and management, invited Dr. Kahler to demonstrate the efficacy of his model in connection with the astronaut selection process. One of the tasks was to determine personality types that get along better than others. And the reason for that was very obvious – a few people need to spend a lot of time together in a small space, in stressful and potentially dangerous circumstances. Process Communication Model has been used extensively in the selection, placement, and training of astronauts in NASA.
Today, the model’s adherents include Fortune 500 CEOs and managers, politicians and prominent psychiatrists.
