Does understanding the question mean Understanding a psychological process related to an abstract or physical object, such as a person, situation, or message whereby one is able to think about it and use concepts to deal adequately with that object? Or is it difficult to then define understanding the question? If we use the term concept as above, the question then arises as to what is a concept? Is it an abstract thing? Is it a brain pattern or a rule? Whatever definition is proposed, can we still ask how it is that we understand the thing that is featured in the definition? Can we satisfactorily define a concept, still less use it to explain understanding? Or is it just it may be more convenient to use an operational or behavioural definition, that is, to say that "somebody who reacts appropriately to x understands x". For example, does one understands Swahili if one correctly obeys commands given in that language? Will this approach, then not provide an adequate definition? Can a computer be programmed to react appropriately to commands, but there is a disagreement as to whether or not the computer understands the language? Well if that' true then in the cognitive model presented by MBTI, the process of introverted thinking (Ti) is thought to represent understanding through cause and effect relationships or correlations? can one construct a model of a system by observing correlations between all the relevant properties (e.g. The output of a NAND gate relative to its inputs)? Will this allow the person to generate truths about the system and then to apply the model to demonstrate his or her understanding of the question? for example does a mechanic randomly, or algorithmically probe the inputs and outputs of a black box to understand the internal components through the use of induction? Does INTP, ISTP, ESTP, and ENTP all use Ti and are they usually the best of the 16 types at understanding their material environment in a bottom-up manner? Do These types enjoy mechanics and digital electronics because of the 1 to 1 correlation between cause and effect relationships in these fields? Does Understanding the question not limite to these types however as other types demonstrate an identical process, although in other planes of reality; ie. Social, Theological and Aesthetic? Does A potential reason for the association of understanding with the former personality types is due to a social phenomenon for asymmetrical distribution of gratification? Does the field of engineering, engineers probe or study the inputs and outputs of components to understand their functionality? Does these components are then combined based on their functionality (similar to computer programming) to create a larger, more complex system? Is This the reason why engineers attempt to subdivide ideas as deep as possible to obtain the lowest level of knowledge for questions answered? If so does this make their models more detailed and the questions flexible? Can it be useful to know the formulas that govern an ideal question, but to visualise the question as being made up of small moving particles, which are in turn made up of even smaller particles, is this the true understanding of the question? Can people who are in need of understanding the question (through the use of Ti) usually value objects and people based on usefulness, as opposed to the people who use extroverted thinking (Te) who view people or things as having a worth? So In order to test one's understanding of the question is it necessary to present a question that forces the individual to demonstrate the possession of a model, derived from observable examples of that model's production or potential production (in the case that such a model did not exist beforehand)? Can Rote memorization be present an illusion of understanding, however when other questions are presented with modified attributes within the query, the individual cannot create a solution due to a lack of a deeper representation of reality?
