Because of regression to the mean, a child's IQ tends to fall between the parents' average and 100.

FAQ

How is a child's IQ estimated from the parents?
A child's expected IQ is estimated to land roughly midway between the parents' average and the population mean of 100. So if both parents average 120, the child's predicted IQ is closer to 110 than to 120. It is a statistical expectation for a group, not a guarantee for any one child.
What is regression to the mean in child IQ?
Regression to the mean is the tendency for a child's IQ to drift back toward the population average of 100. Parents far above or below 100 tend to have children closer to the middle than they are. It works in both directions, pulling very high and very low parent scores toward the center.
How accurate is a predicted child IQ?
A predicted child IQ is a rough estimate, not destiny. Real outcomes vary widely because genes, environment, nutrition, schooling, and chance all play a part. Treat the number as a ballpark expectation rather than a forecast of any individual child's future.
