As players are drafted onto sports teams out of there respective university, disussion surronds their strengths and weaknesses. Various metrics are used to gauge the potential of players in offense and defense positions. The term intangible is used to describe traits that a player may posses which are not quntifiable. This idea can be extended to the area of learning as well.
Knowledge is concerned with learning, just as much as it is concerned with knowning. Levels of knowledge can be divided into three distinct categories; Theorectical, Experimental, and Practical.
Theorectical knowledge can be viewed as the information we acquire from sources such as books in order to understand the concepts and ideas that surrond a particular subject. They are often on the cutting edge of a given subject as they exist thought. If an analogy to schoolwork is created, this would be the test score received for the material lectured on and presented in a textbook.
Experimental knowledge involves taking base level principals and applying them to the physical world. They are implemented in some form and do not exist purely as thought excersices. The nature of the real world must be addressed in order to understand the limitations of ideas. The outcome of an experiment is determined in relation to the expected theoretical model.
Practical knowledge is a form of knowledge that places ideas into a space that allows actual implementors to solve the daily problems that they face. These solutions often deviate from their idealized form as real world principals deviate from the standard textbooks. It in a way, a combination of thoerectical and experimental knowledge.
These areas of knowledge are not mutually exclusive, as eluded too, and build upon each other.
In engaging with various people of different disciplines, some are bold to assume they are absolutely correct in their understanding of a particular subject. They will even go so far as to make incorrect statements to create the illusion they are subject matter experts, and do so without regard to whether their statements are true or not. All that matters is that to the group they address, they appear correct. This can work so long as their are not any other subject matter experts around (something that is becoming more and more common today as feilds become increasingly vast).
Others understand where the limitations of their knowledge are, and will venture no further in discussion on matters they do not fully understand. As Confucious said, 'to know what you do not know, that is true knowledge'.
Yet there is another group of people, those who can be of great benefit in any scenario, by understanding their inherent strengths and weaknesses at any given moment. This reference point allows for them to admit they may not be correct, but past experiences have allowed them to make judgements in situations where noone may absolutely know the answer. They can make educated speculations without given the feeling they are stating facts. These situations are often the case when dealing with practical knowledge and problems.
In this way they are subject matter experts who can contribute to problems outside of their given field. That is intangible value.
