Many people go through life in a rather hit-or-miss fashion, casting about for ideas to explain why their projects improve or decline, why they are successful or why they are not.
Guessing and "hunches," however, are not very reliable. And without the knowledge of how to actually investigate situations, good or bad, and get the true facts, a person is set adrift in a sea of unevaluated data. Accurate investigation is, in fact, a rare commodity.
Man's tendency in matters he doesn't understand is to accept the first proffered explanation, no matter how faulty.
Thus investigatory technology had not actually been practiced or refined.
However, L. Ron Hubbard made a breakthrough in the subject of logic and reasoning which led to his development of the first truly effective way to search for and consistently find the actual causes for things. Knowing how to investigate gives one the power to navigate through the random facts and opinions and emerge with the real reasons behind success or failure in any aspect of life.
By really finding out why things are the way they are, one is therefore able to remedy and improve a situation-any situation.
This is an invaluable technology for people in all walks of life.
