It is commonly believed myth that personality testing instruments can measure your personality and predict your future behaviors. The pre-employment testing mechanism has been following this creed without any solid-state evidence. The testing industry claims complete out validity. The educational institutions and employer organizations use them for screening purposes. Their transparency and equity has even convinced the courts of law. But it is still an unresolved riddle; what do they test? Do they test personality? What is personality then? What is its nature? How does it come into existence? Is it outcome of evolution? Does matter has capability to generate a personality? Why animals don’t have a personality? Does it remain the unvarying during whole of your life? And many more questions.
