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.

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

For those who want a streamlined estimation of their most likely type. This is an entirely text-based service that involves:

  • A short email exchange (3-4 emails).
  • Most likely type, and secondary alternative.
  • Type descriptions for each.

Type Service Tier 1 – $80

A more in-depth service including an hour length video call to iron out uncertainties and explain the type in more detail.

  • Hour-long video call.
  • Email exchange.
  • Most likely type, and secondary alternative.
  • PDF report.
  • Additional 30 minute call to answer questions.

Type Service Tier II – $120

A full exploration of type dynamics and two one-hour video calls to explore the type and underlying functions in more depth.

Includes full CPT Type-Score to demonstrate exactly how each function is expressed within your cognition.

  • Two hour-long video calls.
  • CPT Type-Score.
  • Email Exchange.
  • Most likely type, and secondary alternative.
  • PDF report plus CPT Type Score.
  • Additional 30 minute call to answer questions.


Highly Objective and Thorough

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
28th April 2020

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.

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!

Thorough Typing

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!

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.

28th December 2020

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 🙂

Interesting Theory, Disappointing Typist

Rated 2 out of 5
7th October 2020

Greetings, it took me quite a while to decide what I would properly score my experience with the tier II type service. I deliberated between 1.5 and 2.5 for while. However, this site does not have the option for that. So, I decided to score it in a more objective way to orchestrate my experience.
– Was my experience getting typed enjoyable?
– Were the results clear and easy to understand?
– Was certainly or at the very least, clarification of some element of type achieved?
– Would I pay the money again or advise others towards this typing service?
If the answer is no to all of these questions, the service would get a one star. If the answer to all of these questions was yes, the service would get a five star.
Let’s start with the first question:
“Was my experience getting typed enjoyable?”
The short answer to this question is, yes! Harry is quite an enjoyable guy to talk to. Some of the questions he asked and the way he asked them were intriguing to say the least. As someone who types people himself, even I didn’t ask the variety of questions he does. Additionally, the back and forth banter between the two of us was really fun and had me looking forward to seeing the results. After the interview, I asked him for the notes he took during the interview. He gladly obliged. Through the notes, I could tell he paid attention to my answers and gave thought to them. This would be a clear star in my book.
Onto the next question…
“Were the results clear and easy to understand?”
The short answer to this question was, no. To say the results in the PDF provided were needlessly complex and convoluted would be generous to say the least. As someone who types, a problem I see many people run into involves a difficulty comprehending the functions and what they mean. Thus, I try my best to explain the functions in a simple way before I dive into theory. With his document, even with my experience dealing with multiple branches of typology, I found it difficult to follow the majority of what he was writing. I had to ask for clarification from him on multiple regards which still left me with more questions than I had answers. Lastly, what left a sour taste in my mouth was that he stated that further explanation would require me purchasing a consultation. Considering the type service is $120, and the purpose of the service is to explain your thoughts of someone else’s cognitive type, I find this to be poor practice. The questions were not rooted in alternate theory or idle discussion; it directly pertained to my type, how to interpret his scores, and how he came to conclusion he did. I’ll expand more on this in my next point. However, it is clear he would not get a star here
Onto the next question…
“Was certainly or at the very least, clarification of some element of type achieved?”
First, to orchestrate my point, I will tell you what I was typed. ENTP… or ENTJ… the way he put it… “70/30”. I understand as a typist myself that 100% certainty sometimes cannot be attained. However, this is why you expand on the client’s perspective and have a discussion with them. If the odds were even 90/10, I would feel better about this. However, 70/30 leaves a lot of room for error. Additionally, he provided very little reasoning as to why I fit ENTP more than ENTJ, and very little reasoning as to why I was these two types in general. In fact, the document itself consists of my CPT scores, without reasoning, and the type as a whole and how they can manifest. This leaves a very “take it what you will” turn to it which, again, left me with more questions than it did answers. Considering the obvious difference in valuing functions, it was like saying I liked either Coke or Pepsi when I asked which beverage company would be the best for me. Overall, this was by far the most disappointing part of the service. Not only was the reasoning lacking, but the unwillingness to explain it without additional monetary compensation was just sad. I understand, money is needed, but I paid $120. He devoted two hours for the video call, an hour for explanation of the scores alone, which he said he “normally would only devote 30 minutes of work to the email correspondence”, and however long it took him to contemplate and decide. I type for free, and I devote about equal time and extended correspondence to the people I typed. I found it incredibly disappointing that I paid $120 to be told further clarification was essentially locked behind a pay-wall. If it wasn’t clear already, I was the most dissatisfied with this portion.
Onto the last question…
“Would I pay the money again or advise others towards this typing service?”
I don’t even need to think on this one, it’s an absolute no. While I find the theory very intriguing, I cannot recommend his services with a good conscience to anyone who remotely wishes to receive clarity of type and does not trust a conclusion he gives without proper reasoning or even certainty.
Overall, I believe Harry is very interested in the theory of CPT, but that’s all. When typing someone, he fails to show proper reasoning, fails to show how the type applies to the individual, and fails with quite a few other practices involved with typing someone. Note, the time I invest is normally within a day, and for free. The typing took over two-weeks for a more than disappointing outcome. I was interested in the theory, so at least I gained something. However, did I gain any certainty of my type, or even anything to go off of? No, not really. According to him, again, “70/30”.
So, if you want someone who’s fine with locking you out behind a pay-wall for an opinion on your type that even he himself considers 70% accurate at best, then sure, pay the $120. However, I will not, and I will make sure anyone who asks for my opinion will hear the points I brought up in this view.
Nothing but love to Harry, but I cannot agree with how he does business and how he types people.
2 out of 5 stars, which could have easily become a one star if I wasn’t interested in his theory or if he wasn’t polite.


Response from Cognitive Personality Theory

Hi Siney,
Thanks so much for the in-depth review, and I’m so sorry you were disappointed with the service. Allow me to respond to each point in turn:
1) It is true there is a lot of information contained in the pdf, but I must add my service is a Type Service and not a course on CPT – I provide content on the YouTube channel for that purpose. I totally understand why me stating the necessity of a paid consultation for a complete unpacking of your results may leave a sour taste in your mouth, but I feel you underestimate the amount of time that goes into the typing service. Many practitioners charge much higher than I do for a single one-hour call, absent any additional email correspondance, whereas I put in additional time after the call to reach a considered conclusion as well as explain what the results entail. However, dedicating extra time to completely unpacking my methodology for you is far, far beyond the scope of a $120 type service and would be more equivalent to a training course. I explained in two seperate emails what the scores meant, and every person besides yourself has been satisfied with the correspondence at the end of the service – what you desired was beyond the scope of the service, which is why I suggested an additional consultation. I’m truly sorry that left a bad taste in your mouth, and if the additional questions you were raising were answerable in, say, 90 minutes, I would have gone the full extra hour for you.
2) I did provide my reasoning for my conclusion. I did say I would usually dedicate 30 minutes for email correspondence, but honestly it does end up taking an hour each time as giving a thorough explanation is important to me; in your case, it seems I let you down on this front, and I apologise. Your feedback is giving me pause to consider a Tier III service, as it is clear there are people out there who desire more content than the Tier II service currently provides, and it does sadden me to know you’ve had such a poor experience.
3) I did explain my reasoning to you, and did dedicate additional correspondence over the course of our interactions. I got the impresion you were unfamiliar with the content of my YouTube channel, and did refer you to a full video of mine unpacking the information you desired when applicable. The idea that I lock my explanations behind a pay wall is slightly offensive and I do not consider this accurate in the slightest bit. I am sorry I let you down on this front and if you like we can have a 30 minute chat for free explaining the results more thoroughly.
Regarding the 70/30 ratio, most of my conclusions are indeed 90/10, but I am sorry I was not able to provide more certainty in your case. That being said, I did provide explanations as to why I reached the results I did 🙂

A helpful experience, highly recommended

Working with Harry was a pleasant experience. He’s approachable, yet thorough. I feel well-served in my introspective journey. The final report provided a deep dive into my natural inclinations, and how I interact with the world. I recommend the Tier II service wholeheartedly to anyone interested in learning more about themselves.


Response from Cognitive Personality Theory

Hey David – thanks so much for these words! It was a pleasure to get to know you and I wish you the best in your introspective journey 🙂


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.
