One should know his/her IQ score and use it to evaluate one’s self, but indiscriminately, objectivity should be maintained. For some people, knowing their IQ helps boost their self confidence and morale, and eggs them on to attempt new things, fight challenges or to tax their mental resources and stretch the arch to scale greater heights. For others, it may have adverse effects. Learning that one’s IQ is below average, can be a shattering experience. They may withdraw into themselves and tag themselves complete losers who would never taste any fruit of success.
Importantly, IQ testing does not measure practical intelligence or creativity (Sternberg, 1988), The bottom line is that a high IQ does not guarantee success, but it probably means that such individuals may need to work less hard than people with lower IQ to achieve the same result when intellectual output is required. High IQ individuals should not ‘waste’ this natural ability and should strive to apply it to whatever it is that they seek to do.
Conversely, people with lower IQs are not doomed to failure, but may on average need to work harder to be successful in their intellectual pursuits. It is not to say that having an IQ of 105 (i.e. normal intelligence) would make it impossible to become a professor in Chemistry and to publish in scholarly journals, although on the whole, lower IQ persons will probably face a steeper uphill journey than their higher IQ counterparts striving for the same goal.
