It means your genes have less random mutations, one frequent effect of random mutations being lower intelligence.

If you want to tell whether you're smart or not, do a reaction time test. Extract the delay time of your mouse and monitor.

>Researchers have reported medium-sized correlations between reaction time and measures of intelligence: There is thus a tendency for individuals with higher IQ to be faster on reaction time tests

>Reaction times are so easy to do that 9- to 12-year-old children can perform them in less than 1 s. On these simple tests, children with higher GMA scores perform faster than do children with lower scores, perhaps because reaction time measures the neurophysiological efficiency of the brain's capacity to process information accurately—the same ability measured by intelligence tests (Deary, 2000; Jensen, 2006). Children are not trained to perform well on reaction time tasks (as they are on certain paper-and-pencil tests), so the advantage of those with higher GMA scores on these tasks cannot arise from practice, familiarity, education, or training. Simple reaction time (SRT) measures correlate with IQ ~ 0.20, while more complex choice reaction time (CRT) measures correlate ~0.40. In aggregate, RTs can correlate 0.70 with IQ (Jensen, 2006).
