Are You A Genius?

Dr David Wechsler developed a means of classifying IQ scores called the Wechsler Adult Intelligence Scales (WAIS). The scales are the most widely used and accepted means of classifying intelligence and are regularly updated to account for the FLYNN effect. Currently in its 4th revision the scales are presented below:

Classification IQ
Very Superior 130+
Superior 120-129
High Average 110-119
Average 90-109
Low Average 80-89
Borderline 70-79
Extremely Low 69-

Does IQ Predict Success?

This is a question researchers and anyone who has completed an IQ test will ask themselves. What does my IQ score mean? There have been quite a number of studies and meta analysis designed to answer this very question and the answer is a little involved. An IQ test does provide an interesting means of assessing your ability to reason, creativity, verbal and other types of intelligence but it does not account for all factors which determine 'success'. As a predictor of success it is important to define 'success'. In jobs requiring the types of intelligence IQ tests attempt to measure a detailed meta analysis by Dr Frank Schmidt has proven IQ to be a reliable predictor of job performance.

Dr Wechsler stressed the importance of measuring a person's ability to apply their intelligence, not simply their intellectual capacity. What use after all is a high IQ if it's not applied to meaningful problems? In a 2005 study conducted by the University of Pennsylvania researchers discovered that self discipline outperformed IQ in predicting the final grades of year 8 students. It seems that a minimum level of IQ is required for many tasks but beyond a certain point other factors such as your ability to communicate, maintain motivation and direction are also important in determining success.
