Question/Topic: IQ Intelligence Quotient "Regression to the mean" 
Answer/Pointer: Q. Is it true that a child's IQ can neve be higher than his parent"s? A. It's not true. The scientific term for this tendency is "regression to the mean," but it is a statistical phenomenon, not a biological one. It simply means that, within a given population, average intelligence appears stable, and people tend more to be average than exceptional. If both parents have IQs of 125, they are more likely to produce a child with an IQ of 100 to 125 than to produce a child with an IQ over 125, But exceptions do occur routinely---easily accounting for the broad range of ability in society.
