An IQ score of 120 sits in the sweet spot most people don't realise exists — it's solidly in the "Superior" range, but not so rare that it isolates you. Roughly 9% of adults score this high. Statistically, it's the level associated with the highest career success-to-effort ratio.

Why 120 Is the "Sweet Spot"

Research on income and life-satisfaction outcomes consistently finds that the strongest gains from IQ occur up to around 120. After that, additional points correlate with higher earnings only modestly, and may even slightly reduce social ease (very high IQ individuals report higher rates of intellectual loneliness).

An IQ around 120 is high enough to handle nearly any cognitively demanding career, yet common enough to find peers who think similarly. Many of the most successful entrepreneurs, managers, and creatives test in the 115–125 band.
