The IQ rating scale is actually a statistical reflection of scorings that different people achieve from a particular community and in a specific age group. For that matter your mental age is operated with your chronological age, and the result is multiplied by hundred for normalization.

Lewis M. Terman, expert of psychological science, is actually mentioned to develop IQ rating scale with the name of Intelligent Quotient. He has been using IQ assessments to understand subjects’ exact intelligent ratio with various other prospects in the given conditions. The subjects who scored better were included in the category from average to the genius and even super genius people. The people with the lower scores were included in the categories of below average to the mentally retarded people.

But we have learned during the years that such scales work very fine for the people on both extremes. In other words they are successful to find out the people with extreme low or extreme high IQ scores. However, they have been failing very badly to measure potentials of the people with average IQ scores.

However it is certainly not easy to persuade professional mentors and concerned moms and dads to not undervalue the ability of so called weak minded people. It is even a lot more complicated to convince them regarding ‘superior’ kids not to overrate their outcome.

We can easily witness numerous prosperous individuals having lower IQ rating at one particular phase of their lifetime or the other. The wasted intellect is a lot more exposed because of to its rareness and extreme amount of targets.
