Some may say that the top 10% of IQ would be those scoring an FSIQ of about 125 or above. On the normal distribution curve, one would find a preponderance of these individuals clustered toward the low end (near 125), as higher IQs simply occur less frequently. Over time, several articles have indicated that an IQ of 125-130 may be an optimal; Individuals with higher IQ may suffer from lack of intellectual peers, paucity of appropriate academic challenge, and dearth of affirmation, understanding, acceptance, and support.

It is important not to conflate giftedness and opportunity.
