How it works

Finding your cognitive type can be an incredibly difficult process, with much of the various videos and blog-posts on the internet doing little more than sew even more confusion into an already complicated topic.

The CPT Type Service prioritises self-discovery over simply being handed a type code – for this reason, a back-and-forth dialogue is essential for effective results. No one person is exactly the same type as another, and as such the emphasis is understanding your own individual cognition, rather than just one of sixteen variants.

After purchasing a specific service, please fill in the application form accessible from the menu of the home page. This will supply the information necessary to form a preliminary estimate of type and narrow down the options.

The video-call available in Tier I & II is not only an important means of confirming type and selecting from the options previously elucidated, but also to answer any questions that may arise in understanding the results. For Tier I & II, I take additional time after the call to formulata a conclusion and provide a written analaysis – the prices for these services reflect the extra time investment outside of calls.

All services supply an additional selection of types in order of likelihood, should there be any doubt as to the primary results.

Type Service Basic – $70

Highly Objective and Thorough

Rated 5 out of 5
12th May 2020

First off, I don’t trust most people’s objectivity, especially when it comes to typing as many interpretations can arise from a single statement/source of information. This happens all the time when I bring up being a clairempath. Something which, contrary to belief, is not tied to cognitive stacks. Rather, it is something that occurs outside such things and stems from another source than human cognition patterns and their ability to perceive things (however, that is another subject matter entirely). The fact that he has the ability to recognize and acknowledge this was a big selling point in the final analysis. Most people become too enmeshed in their own perceptual biases, which is why I chose to go with Harry here. You can have absolute faith and trust that he will understand and objectively analyze your inner workings without pre-conceived notions of behavior that often lead to misunderstandings and mis-typings. We are all equally complex beings and he’s definitely on the right track.
If you have any doubts or don’t know who to go with, I can’t recommend him enough. Though I am moving on to my next path, if you find yourself here, stay for a bit and consider a consultation. You have nothing to lose, only to gain.

Finding the cognitive functions without relying on stereotypes

Rated 5 out of 5

I am very satisfied with the typing service. Harry’s Typing does not refer to the stereotypical behaviors and statements of the different personalities, but on the underlying patterns. Even after the interview he is very accommodating when questions arise and answers them in detail so that they are really understood. I trust his competence and knowledge and I also have absolutely no need of having the result confirmed by another coach, because he could explain very well why I am this type and not that type.

Thanks Paulina – I’m glad the service was of value!

It was very hard for me to understand my personality type because I could relate to several types. Sometimes I bring an unconscious functions into consciousness, and it confused me. Harry was able to help me understand my personality type, and I how I dip into other cognitive functions. I’m very happy with the results.

Thorough typing and great feedback

Rated 5 out of 5

I wasn’t impressed with other typing services, as most of them tend to focus on the very simplistic interpretations and even more simplistic questions, which can be answered in a variety of ways depending on ones mood. Harry asked insightful and thought provoking questions which in addition to type gave me an insight into myself, and a different perspective on some of the issues. We found ourselves agreeing on the cognitive axis and Harry was kind enough to take my perspective on the type into consideration, and gave a thorough explanation on his perspective, as well. I would recommend Harry to anyone who is struggling to find their type amidst the sea of different systems, as I think that the explanations are more than adequate and take into consideration the basis of the Jungian theory.


Response from Cognitive Personality Theory

I truly appreciate this feedback my friend! It was my pleasure to provide additional clarity and insight into your cognitive processes 🙂

Excellent Typing Service

The tier 2 service was what I purchased. Harry was very kind and pleasant and answered any questions I had. He provides a thorough explanation of what type you could be. I found myself discovering more about myself throughout the sessions. He helps debunk a lot of misconceptions in the type community and provides a document that succinctly showcases the subtleties that you specifically can have for that type. I highly recommend this service.

Hey Tharu, it really means a lot to hear this from you! It was great meeting you and I’m so glad the service was valuable 🙂

Extremely High Quality Service

Rated 5 out of 5
12th September 2021

I booked Harry’s Type Service Tier II because I was questioning the type I had gotten from an online test. I had been researching MBTI and cognitive functions, but found a lot of the current theories out there to be quite rigid and lacking in nuance, e.g. when they say if you have one function you by definition can’t have another.
Discovering CPT was like a breath of fresh air. Finally, an explanation for cognitive functions that made sense and allowed for the possibility of people to use their type as a springboard for growth rather than a box they could never leave.
I’ve greatly benefited from watching the videos online and also from reading the e-book, which provides an excellent explanation of the theory.
Meeting with Harry in the online interviews was a very pleasant experience. He is professional, friendly and a great listener, making you feel comfortable from the start. I actually really enjoyed answering the questions he posed about my personality and how I experience life – this alone helped me learn new things about myself that I hadn’t considered before.
I was very satisfied with the final report: it was very detailed and showed a good deal of insight. The type Harry suggested for me feels much more correct.
All in all, this was a wonderful experience and I highly recommend this service!

I purchased Harry’s “Type Service Basic.”
Harry provided a very thorough assessment, with plenty of explanations on what he observed and how he believed those correlated to a given function. I could see the amount of effort and time he put in to the assessment and to clarify follow up questions.
I would highly recommend Harry as a knowledgeable and thorough typist.

My impressions on T1 typing service

Rated 5 out of 5
8th April 2021

Having this Tier 1 typing experience with Harry was great
1) he’s a very nice human being. Patient, kind, open, adaptative, apparently honest and pationate
2) I like how CPT theory seems aiming to self development and understanding the roots of your CFs instead of the entreprenarial effeciency that MBTI gravitates upon most of times.
It’s out of stereotype, breaks with misconceptions. Being, to me, more accurate, this method consequently fills less boxes with short, easy answers but offers more in depth reflexions. Greater value for me but comes with work. There’s a whole bunch of complementary explanations trough the youtube content.
3) Being typed in France (i’m French) cost around 300 euros (330$) and it only grants you 2h videocall with someone that can easily be less accurate and “in deep” oriented that Harry is for 90euros. He gave me some extra time and offered me the possibility of email exchange (that are coming ! Harry if you reading this… (; )
So, in the end, the experience was nice, serious, very interesting and not expensive.
Thank you Harry !

Other 5* reviews have said it all already! 😀

It was genuinely nice meeting Harry – he was extremely friendly, patient and non-judgemental. It was certainly a pleasant experience. As for the service itself, I received my two hour call in two parts, and at the end of each, Harry gave me to type he was leaning towards and why. He was happy to paraphrase when I couldn’t understand what was being said and REALLY listened to everything I said. After Harry had taken some time to analse the recordings, I recieved a comprehensive email with examples or things I have said and done that would relate to which function and time references to the recordings so I could look at them again – I requested copies of the recordings too and Harry was very accommodating. And now that the service is complete, I have still been bombarding the poor man with emails, and he still seems happy to answer all of my questions. What a guy! I am very happy with the service and truly believe that it was worth the money and deserves nothing short of a 5* review.
Disclaimer – if you are new to the theory, go to Harry’s YouTube channel first and learn about it there, or read the book. Buying this service without any prior knowledge is not recommended, so do some research first and then buy the service.


Knowledge is Growth

Being someone who is very fascinated with personality theory and others perspectives of it. I purchased one of Harry’s typing services. After listening to many of his YouTube videos I was curious about meeting the man and learning more about his methodology and what CPT had to offer. The questions were incredibly well thought out, and really makes one stop and dive deep and swim inside oneself. I was impressed with what he was able to pick up on as well as breakdown. Harry is incredibly informative, insightful, and friendly. For anyone out there looking to understand oneself and grow or even expand upon their own knowledge in personality theory I would highly recommend checking in with Harry!

Thanks so much Anya! I really appreciate the kind words and it was great talking with you!

Clear Look at Typology from a New Perspective

Rated 5 out of 5
27th January 2021

Harry’s CPT is a remarkable way of learning about the various cerebral components that comprise individual personality. By using terms and ideas sourced from Jung, Philosophy, and Psychology, Harry has synthesised an entirely original contemporary understanding of typology. As a Jungian and Depth Psychologist, I was immediately interested in what Harry would come up with so I purchased the basic type service. I couldn’t me more happy with Harry’s professionalism, the care he took in coming to my type, and the presentation of why he came to his final conclusion. Considering the price, this was an extremely valuable experience I felt I got at a total steal!

For about a year now, I’m been very interested with the broad area of personality type. I discovered Harry’s channel on YouTube and was amazed at his new system. While very theoretical, it’s clear to me that his information is very well thought out and not to mention fascinating! While I always received a particular type score on websites, I couldn’t rely on them too much as their algorithms are unknown and follow up questions and further exploration is impossible. So I knew I had to go to someone that appears very well informed, non biased, honest and is willing to explain things clearly. After being typed by Harry, I was very happy with my result. My primary type was slightly different than websites told me, but my alternate is the same. That said, it’s clear to me now that Harry’s primary type given to me actually resonates more than what all these different websites gave me. I now understand myself much better, from my thinking patterns to why I do things the way I do and understand where I need to develop. I also much better understand other people and how my personality relates to theirs. Although a websites may be a basic starting point, we don’t know what their algorithms are to decide what type you are, and of course they can’t ask you follow up questions like a person can. So I highly recommend Harry’s service for anyone looking for a great typing service.

Rated 5 out of 5

Though I was still quite new to Harry’s theory, I decided to purchase Type Service Tier 2 because I agreed with the general ideas of CPT, which are type fluidity, and individuation. I’ve always thought that the orthodox MBTI is limiting since it basically assumes that there are only 16 configurations of cognitive functions, but in truth, those who share a same type can have slightly different preferences.
You may think, just by reading this, I’m some some sort of a Ti user. Yet I was typed an INTJ (or INT-Fs in CPT) by Harry. And it makes total sense. While I do occasionally “dip” into Ti, my default state clearly seems (convergent) Ni-Fi. Most of the goals and interests I form are related to my identity in some ways. And I sort of just use this intense Te-Se focus to get to my goals.
Anyways, enough about me, I 100% recommend getting typed by Harry if you want to figure out your real type, and just how you use each functions. I’m sure lower tier services are high quality as well.
Thank you once again for the great sessions, Harry! (I hope the review isn’t too long, haha)

I purchased the basic type service, which was done over an email exchange. I feel that all the questions that were asked had been carefully thought out and I even had to take some time to consider how to answer some of them, as they were things I had never considered before, and I wanted to answer as honestly as possible. Overall it was very interesting and Harry was helpful and friendly as well. In the end he was able to give me a confident conclusion as to my type, and I could see that the conclusion was correct, even though some aspects of it were surprising! Would definitely recommend 🙂

I purchased the Tier II service.
This was a great experience! Harry is pleasant to work with, precise with his questioning, and provides timely feedback.
I would recommend him to anyone interested in an in-depth exploration of his or her type. The information he provides at the end is very detailed and informative.

CPT methodology is employed for the effective understanding of type cognitive dynamics – the more you know yourself, the more effective CPT becomes.

The typing of other people within a short space of time blurs the line between cognitive and behavioural psychology and will seldom be 100% reliable, but narrowing the options down is relatively straightforward and in many cases a type-code will be given with certainty.

Transparency is also highly encouraged – if your thought patterns indicate one type, and your words another, CPT will place greater value on the underlying cognition. It is my obligation to indicate the type I believe you to be, and help you come to your own understanding of this.

CPT Terms & Conditions

  • All private and confidential information, including your name and contact details, will not be shared with other companies.
  • All results are stored within an existing database of case studies for research purposes – aside from customer records, full names and other personal information are removed to protect individual privacy.
  • CPT methodology is an extremely effective means of determining type, but like any other system cannot ever supply absolute certainty in this regard.
  • CPT is not a substitute for professional psychiatric, or other government-licensed mental health services – any mental health conditions, including clinical depression and personality disorders, should be treated by a specialist.
  • The focus of the Type Service is to elucidate a person’s innate predispositions – as such, while the focus is centered around the individual in their current state of development, questions may be asked pertaining to childhood, life journey & direction. Answering such questions is not compulsary, however, and personal information provided by the client is treated as confidential.
