Tests of general intelligence

The three existing methods to determine mental classification of army personnel have several drawbacks. The method of trying out involves trying out each soldier in tasks of various degrees of difficulty. Although fairly sure, it is very slow. Pseudo-scientific methods of rating mentality involve phrenological method of determining definite and constant relations existing between mental traits and contour of head. However, it lacks scientific support. The method of off-hand judgment involves determining mental traits on the basis of ordinary observation. The method suffers from lack of universal standard of judgment, inter-judge agreement and is misled by language and appearances. The Intelligence tests involve analysis of typical samples of intellectual activity and yield good predictive results. They are objective, standardized and are little influenced by the educational variables.
