You are mistaken. First of all, neither one of human manipulation modes is more difficult to use than all others. All that is required in case of transmission of any one of human manipulation modes is to have the manipulation scenario, to act it out like a role, without making any adaptations, and to monitor reactions. It is also desirable to have images, by which the manipulation mode being used is recorded in the unconscious of the person you are manipulating.
Secondly, any one of manipulation modes can demonstrate effectiveness of use of information from the Catalog of Human Population; especially if a person is a professional and knows at least how to monitor reactions of subjects.
Speaking of reactions… Without knowing the Individual (Subtype) Program of a person from the Catalog of Human Population, even a good professional is not able to correctly interpret that what he/she sees. Since, again, 293 human subtypes exist in nature and each one is endemic, and reactions to any one of manipulation modes entirely depend on the subtype’s program. Therefore, it is desirable for the manipulator to have information about the Individual (Subtype) Program of the subject of his/her manipulation.
However, this is probably quite complex for a beginner and cannot be explained in a nutshell. It probably makes sense for you to read the book devoted exclusively to natural human manipulation modes titled Human Manipulation Modes: Either You Are Manipulating Or You Are Being Manipulated (by Olga Skorbatyuk and Kate Bazilevsky).
