First, thank you for checking out the site!

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.

I upload videos to the YouTube channel on type comparisons, self-development and entirely new ways of understanding cognitive type.

I hope you find the content on website and channel informative, and be sure to reach out via email to [email protected] should you have any enquiries.

“Excellent Book! (5 Stars) This book was incredibly interesting, and I have read many on the subject of Jungian typology. The type descriptions were impeccable, and the explanation of the function stack made a lot of sense to me and provided what seems to be lacking in so many other typological theories. There was also an excellent discussion of the transcendental function which showed how it might exist in pragmatic form. I therefore highly recommend this book to anyone who would like to see how the cognitive functions are actually expressed in people.”

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.

I started to watch CPT on YouTube and I was sold with the knowledge and technique Harry uses. Then, I bought the book and after reading it, quickly realize he knows his stuff. Especially how he focus on flexibility and not getting caught up in dogmas. I’ve been for years trying to figure out my type but I couldn’t, so I decided to get the type services and after few emails and a video conference, Harry was able to type me and even connected the second Type thought I was to the core one. If you want to really know your type Harry is the guy. Excellently done ✅! I’m very happy with the result and the accuracy. One more thing, Harry takes the types out of the behavior focus and it removes stigmas and even misrepresentation of types is out there. He leaves room for potential, flexibility, and growth! Very happy and comfortable ENTP with some INFJ qualities.

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.

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.

I went with the Tier II service because I wanted to go for the full experience, get a sense of the full scope of Harry’s methodology and see what he & CPT are all about. Harry is super-organized and super-invested in working with you individually, getting to know and understand your personal context. There’s nothing rushed or mass-manufactured about his process, and he takes the time to get to understand you and your story.

Here are some suggestions for people considering the service:
1 – Yes, there can be a lot of jargon. Do not be shy about asking Harry to rephrase things for you. He’s very responsive and will break things down for you.
2 – If you’re taking the Tier I or Tier II service, I suggest spacing out the email exchange, the Skype call, and the follow-up Skype call – instead of doing things all at once, it can make sense to do this over several days or even a couple weeks to capture yourself in different mental states.

When Harry says he’ll get results to you in 7-10 days, he means it – that’s exactly what happened for me. The results PDF was thorough & in depth, and it helps that he gives you a “most likely” type as well as an alternative possibility. Even if the most likely type is a certainty, it helps to have different possibilities to look at, to weigh and assess.

Finally, as a doctoral student, I’m used to living on a budget, and I feel like every penny was well-spent here. I’d gladly go through the process again.

I’m so glad I found CPT and Harry, respectively the first no nonsense modern theory based on Jung’s typology and the first professional typologist I encountered, and I stretch the word “professional”. I’ve been trying to find my type for many years without success and then Harry, after a careful analysis of the information I sent him and based on the information he gathered during our video call, came up with a type I haven’t even considered using the Myers-Briggs system. CPT’s result makes sense and actually explains lots of stuff about me. And the best part is that I have already started to use that knowledge for self development. Also, the whole process was lots of fun and I could tell that Harry is really passionate about helping people like me to understand themselves better. And it works. And the price of his service is very low compared to was you get in return. Worth every penny. So I’m a very grateful client. Thanks a lot Harry!

Francois, Client

Talking with Harry is like talking with a really good friend…except the conversation is all about you! I am not usually very comfortable talking to a complete stranger about my inner workings, but Harry made the experience easy. Two hours sped by, and I eagerly awaited the results, which came–exactly as promised–ten days later. The analysis I received was thorough and enlightening, and started me on a process of self-examination…which is ongoing. Getting typed by Harry is well worth the cost! If you are wondering about your type, I highly recommend Harry’s type service.
