I'm a 31 year old male, full-time college student that has come over from the Keirsey Temperament website/forum. I'm displeased with KTT (Keirsey Temperament Theory) because it's strictly based on behavior and not on cognitive functions that make up the MBTI. After getting to Skype with David M. Keirsey personally, he stated that it was to complex to go on cognitive functions and behavior but I disagree because EVERYTHING influences behavior. Hopefully I can meet some like-minded friends here. So, HELLO!
