The average IQ is supposed to be around 100. Around half the people out there have less than 100 IQ. Lead exposure lowers that even further (see Radon gas, light aircraft at small airports and race fuel at small tracks, and still old houses with pipes and paint).
Math is not fun for those people, loud sounds and bright lights are.
