While there may be a genetic component to intelligence, many factors can influence an individual's IQ beyond just parental IQ. Environmental factors, education, nutrition, and early childhood experiences all play a role in cognitive development. It is not guaranteed that having parents with a low IQ will mean you will also have a low IQ.
That would pretty much depend on which percentage of people is higher...High IQ or Low IQ. If the largest percentage of the population was Low IQ for example than they would continue to produce a large number of Low IQ children and those children would then chose equally Low IQ mates the IQ of general society would be low. If the largest percentage of people was High IQ then again the number of High IQ people would continue to rise. High or low eventually society would even out to a fairly consistant IQ level through out the population. If this IQ level is high society may become more advanced and progress. If this IQ level is low then society may fall behind and not progress well.
