Cognitive Personality Theory is a new system focusing on individual differences, positing type not as a set of letters to define who we are, but rather a series of limitations that can, with patience, be overcome.

THE BEST TYPOLOGY FRAMEWORK FOR SELF-UNDERSTANDING

Rated 5 out of 5
16th September 2023

I took already around 13 years in this mbti typology therory, but there were many things I could not make sense of. Here is the framework we all needed and I seriously hope that keeps expanding among all of us that think of typology as something that could help us find answers for our cognition.

Harry’s understanding of typology has been life-changing for me, since I could have neved find my type with those description out there in the internet. Here with Rob I have had a very interesting call in which he has been able to gather aspects that I did not think were telling of my type, and summarize them in a way that describe with an unseen level of precision what is happening in my cognition.

Unfortunately after all, I could not check many sources I did not consulted already, such as Harry’s book and the videos related, since I had already watch them all! Hope they keep bringing more content not only for the “main types” (INxx and ENxx types). They have done and incredible job at NOT describing the rest of the non- N types as something like NPC on the background that basically are very good people a like to do practical things for others.

Please keep it up and thank you very much for your work. Both Harry and Rob!

Easily the most helpful typology purchase I’ve made. Comprehensive, great analysis, and excellent support. If you’re interested in rigorous clarity about yourself, you should not sit on this one.

Thank you Harry for providing a great experience! It’s easy to tell you really care about helping your clients, and you definitely helped me. I think CPT is a very well thought out system, and something you should be really proud of!

To anyone considering buying the service: Harry was very professional and made the whole process comfortable and easy to get through. I would definitely recommend!

Discovered this channel in the end of 2020. CPT helped me a lot with understanding the types, so I stick to this one. Recently I had a typing session with Harry and it meant a lot! Turns out I have indeed an Fi-blindspot just as I thought, which was the cause of constantly mistyping myself through the years despite knowing how the types function. Harry is very insightful and I would definitely recommend CPT to others!

CPT serves as a high quality, in-depth look at personality typology with far more flexibility than most systems have. I purchased the Tier II service and it was definitely very valuable for me. Speaking with Harry was very nice and he was very professional and accommodating throughout the process. His results covered a great deal and I was very happy with them! Would recommend for anybody considering trying it out.

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

I booked the Tier II Typing Service with Harry. Throughout the service, Harry was nothing but professional, open-minded, observant and extremely considerate of your individual beliefs and values. It was like talking to a close friend…. He was able to draw out some of the deepest memories that I forgot I had, and discovered who I truly was.

He worked his magic, and now I’m a happy ENFP. His judgement was so accurate, so profound that once you receive your result, you are certain that you are this type and cannot be any other type. His judgement accounts for the nuances & individuality each person exhibits within the type itself. I felt like I was forever misunderstood in the MBTI community, but thanks to Harry, I now know that I’m just an ENFP with a highly developed Te 🙂

It was an amazing experience. Maybe the Consultation Services next? Highly likely 😉

Well whatever he did, it worked – I am now a Jungian ubermench. Either that or an ENTP. Whichever it is I’m happy for the functions, the language, and the insane conversations about everything (which I can’t remember but were totally worth the money).

If you want to understand yourself and everything else – take a chance. Book a session.

You won’t regret it.

… I mean the verbiage could use some work, but it’s still a very good system. I give it four and a half stars lol. That’s still loads though man like a star is massive.

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.
