"I've been studying Socionics for several years, and Jack's Crash Course helped me understand Socionics FAR better than I ever had before. From theory to practical application, in my opinion Jack is the absolute BEST teacher of Socionics that I've ever come across, and this crash course has been worth every penny!" - William Solomon

"I really enjoyed my One-on-One Q & A session with Jack! He was friendly, patient, knowledgeable, and willing to entertain any question I could come up with. He has a wide range of services including coaching and lessons. Great selection, good prices, and it’s easy to understand and choose what suits your needs the most!" - Rachel Watson

"Highly recommend WSS for a source of information, and also for diagnostic interviews. Jack is absolutely thorough, patient, and really knows how to get people to open up and get to the essence of who they are. He is extremely knowledgeable within the field of Socionics, but also truly understands people and the ways they operate within this framework. Whether you are new to Socionics, or have a level of expertise & just want an expert opinion, Jack will be able to help. The amount of passion & care he has for this field really shows in every interaction and in all of his content." - Kat Passionate

"WSS is the revival that Jungian typology needs. I attended the pilot crash course and the knowledge I gained is world transforming. I never saw the types the same way I do now 10/10 highly recommended!" - Max Million

"I had spent some time learning about Socionics and found it confusing, although deeply interesting, making it quite a frustrating experience. And then I discovered Jack and WSS, and it all started to make sense! Finally, all the potential of model A was unlocked in a very accurate, precise and down to earth way. I honestly think WSS is an extremely rare source of information on a topic that all people interested in personality psychology would benefit from." - Armand Moyon

"There's an art and a science to socionics, and Jack and the rest of the team know how to approach it from both angles. Solid knowledge, and skilled application. If you're interested in socionics, I recommend WSS." - Taylor Briggs

"Clarity and precision, eventually something that reliably works " - Chris Dee

"Great content on the site, specially for those who are starting, and also for those who know more. The typing service is also great, helpful and efficient. The session was scheduled very easily (no problems agreeing with the time, regardless of the geographic distance), and the session started at the previously specified time, (no delays or any other kind of troubles). The feedback was insightful for me. The service is also multi-language, if you don't speak English." - Luis Eduardo Ceballos Camargo
