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 a video to the YouTube channel every week 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 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.
