What an IQ of 118 means

An IQ of 118 sits at the 89th percentile. Roughly 1 in 9 people score 118 or above. One standard deviation above the population mean is IQ 115 — you are 3 points above it. Research consistently shows this range achieves strong academic and professional outcomes in analytical and managerial roles.

IQ 118 in context

IQ 118 sits 3 points above the one-standard-deviation mark of 115 and 12 points below the Mensa threshold at IQ 130. At the 89th percentile, roughly 1 in 9 people score here or above. In large-scale occupational research, IQ 118 sits at the level where analytical and supervisory roles are reliably within reach. The 18-point advantage over the population mean is meaningful in complex cognitive tasks but not so large as to create the social friction sometimes associated with scores at the extreme upper tail. Research on high-performing teams consistently shows that IQ 118 individuals — particularly those high in conscientiousness — tend to outperform higher-scoring counterparts who rely on ability alone.
