While it is true that geniuses are a unique set of people with unlikeable ability to make significant contributions to the advancement of humanity, there is no definite manner in which one can measure the intelligence of a person. It is the reason intelligence is a largely subjective attribute. Science has advanced in a sense that it has developed Intelligence Quotient (IQ) tests measure human intelligence using components such as three dimensional thinking, memory, problem solving, and analytical capabilities. The test assigns scores based on how sharp the brain of a person is relative to the target scores. An average IQ is about 100 and most people will score between 70 and 130 using an adult IQ test while 200 is the highest score that one can obtain.
