From the foregoing it will be seen that each man was graded according to the navy standard on a basis of 1, 2, 3, 4, as follows:Mentally:1. Inferior.2. Low average.3. High average.4. Superior.Educationally:1. Less than eighth grade.2. Eighth grade graduate.3. High school students.4. College.Industrially:1. Misfits or failures.2. Unskilled.3. Experienced.4. Skilled.In addition, each occupation was given a serial number from 1 to 53. This made it possible to give every man a numerical formula representing his capacity and training. The serial number representing his occupation was put at the right of a decimal point as it denotes a qualitative factor, the others being quantitative. For instance, 444.4 would represent a man of superior intelligence, college education and highly skilled, his occupation being an attorney. Also 111.34 would mean inferior intelligence, less than eighth grade education and industrial failure, his work being odd jobs.This enables a simple index, making it possible to locate and evaluate men easily. Also each number serves as a check upon the other, as a man with a 4 in his formula must be taken seriously, and a I means that he should be suspected of incapacity. As a matter of fact the formulas are very consistent, it being rare to find both a I and a 4 in the same formula.Abstract Teaser
