After learning about this system, I’ve found that its structure is highly adaptable. The terms are simple yet broad. The service is surprisingly good and insightful. Although it’s not as economical as one would expect, I totally see why such price was set. Overall, this is top-level typology

Both Harry and Rob are excellent typologists. It is obvious that this is a passion of theirs and they want to understand your cognition as much as you do. This typology is easily the most accurate and in depth for understanding cognition, and these are the experts. My results accounted for nuance and I was very happy with the process.

Amazing services from both Harry and Rob! Both of them are very helpful and respect your time with them

I booked the Type Service Express package with Rob, and his analysis was very accurate and insightful! He was able to accurately type me, and he gave me nuanced insights into my strengths and weaknesses. He took the time to correspond via email and answer any questions I had and he provided tangible examples for me to compare with and observe.

Afterwards, I booked the Coaching Tier II service with Harry to smooth out some areas of my cognition I was interested in which would help me achieve some personal goals. Words cannot describe how valuable Harry’s work and insights are! In such a short period of time, he was able to guide me to smooth out my cognition in such a seamless and painless process. We also had a lot of great talks about type theory in general, and he was able to expertly answer my questions. It’s not an exaggeration to say that this coaching service may have saved me many years of struggling in my own personal growth and development!

Highly recommend services from both Harry and Rob

Thanks so much for this review Matt, it means a lot! You were a pleasure to coach, and both myself and Rob really appreciate the kind words 🙂

CPT seems to be the most accurate and nuanced MBTI system there is.

I was struggling to figure out my type until Rob did a typing session with me. A lot of my doubts on my most likely type came from nuances I saw in myself that didn’t align with the common stereotypes of traditional MBTI. With Rob’s help he showed me that the nuances I noticed in myself were textbook traits of my best fit type according to CPT. CPT takes the more traditional approach of identifying individual cognitive functions and goes further, expanding upon the relationships between the lens and codec functions, examining a person holistically.

It was a joy to get to know you, Michael! Your self-analysis made it real easy, and it was just a matter of properly labeling the concepts. As you said, we strive to look at people for the whole human beings they are! Thank you so much for the review, and best of luck on your journey! – Rob

I had been trying to understand what type I could be for two years without ever coming to any real conviction. Thanks to Rob’s analysis, I finally see things more clearly. I think I needed an outside expertise. And the arguments based on the notions of CPT are helping me to understand better how cognitive functions can influence my behavior.
