I am trying to understand how different types of people got typed, why do you frame a question like that?
I am certain of my type and dont need confirmation at this moment.
If he shares people's videos and types with me, I would pay but he cannot do that due to data protection act/law.
As I said, I am trying to understand how different types of people got typed by watching videos and seeing his conclusions. He has zero benefit and harm from this. As I said, if he shared his database with me, I would pay.
It is impossible to be certain of 7.8 billion's type by watching two videos. Yes, people can get angry if they didnt get what they want. However, some angry or pleased people will be typed wrong.
This is not an arbitrary assumption. Human mind, information metabolism is complex. Everyone goes through different kind of life paths which some evidently effect how their brain work besides socionics. So different type of people doom to possess different levels of difficulty when it comes to typing. Hence, noone can type everyone on earth without a margin of error. My knowledge of socionics is irrelevant, this is not about me or him, noone can do this. There is a margin of error in different kinds of works. Socionics or anything related to psychology is more complex, unknown and unprovable to clarify. Hence I can say this without having an expert knowledge for socionics and other typology, psychology areas.
I brought that up, because I basically say that if he is certain about all people's type without additional videos besides two videos, he will make a mistake and although, you never claim that he cannot do any mistake directly. You are mentioning his phd and experience like you claim otherwise. To be sure, are you saying that he cannot make any mistake about someone's type?
If you do, then you are saying his method/skills are flawless which would be inhumane/almighty since people who have lots of experience and phd in medicine, science, engineering etc can do mistakes, making mistake about socionics's type or attachment style or something related to typology, psychology is much more easy. This isn't about Gulenko, if there was any another socionist I would say the same thing. I can even say noone can type everyone with %100 accuracy. Gulenko can decrease his margin error by asking for additional videos when he is uncertain or refunding as dead suggests. Some other people can decrease their margin errors in different ways. Having a room for improvement doesnt decrease the credibility or success of a work.
