PCM was created by American psychologist and university professor Dr Taibi Kahler in 1970’s
Researching communication, Dr. Kahler spotted certain patterns of behavior that are related to positive and negative reactions
He also recognized entire series of negative behaviors that are related to stressful situations.Taibi concluded that based on the words a person chooses and how they behave, we can predict their reactions in stressful situations.
Relying on Transactional Analysis(psychotherapeutic method known as TA), Taibi started a number of studies that led him to the conclusion that every pattern in speech and behavior can be linked to one of 6 personality types.
