dear friend,
psychometric means measuring the conscious part of mind. human mind is like a iceberg. what is visible is just a grain. the invisible has many aptitudes, attitudes, skills and knowledge which are not seen at one go. they come out only at appropriate situations.
In todays competitive world, organizations want people who not only perform in the present but also possess sufficient stuff for the future. Organizations want people who can work under conditions of risk, uncertainty, conflict, etc.
In this backdrop, organizations are trying to extract the invisible part of the iceberg through various tests. These tests are in the form of MBTI, FIRO-B, MAO-B etc. You can give these in the google search to find out more about them.
