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.

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.

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

I came to correct my 1 star review to a 5 star one.

Harry, was very kind just by refunding my basic service that I purchased and he still delivered his analysis. That gave me confidence and I decided to go for the Type I service which was amazing to be honest.

We had a really good talk, I enjoyed it quite a lot and in the end I was very satisfied with the answers I got

Hi Tom,

Harry asked questions which made me think about some things which I wouldn’t have considered when typing on my own. He gave a wonderfully detailed analysis of the most likely types as well the types’ descriptions. This typing service not only helped me understand myself, but also allowed me to use that understanding of me, the subject, as a vehicle to understand CPT and the functions in general, and how it applies to others. Truly an eye opener.

Submitted my answers to the question more than a month ago and I didn’t receive a message when I sent them an email asking if they got it at all or something, some info would’ve been nice

Still waiting 🙁

Tom

Response from Cognitive Personality Theory

Dear Tom,

Please accept my apologies, your purchase went entirely under my radar during a busy period and I feel terrible that you have been kept waiting this entire time. The one star review is entirely justified.

As an apology I have issued you a full refund, and have already started analysing your answers – a type conclusion should be with you by early next week.

Harry
