It doesn’t take long for parents of teenagers to trip over a difficult truth every parent of teens must learn to accept: teens believe that parents are about as smart as sea urchins. A direct correlation exists between the age of a child and his or her perception of a parent’s intelligence. On average, children aged 0 to 12 believe their parents possess an IQ greater than Albert Einstein. Children aged 13 to 19 think their parents are semi-moronic. And as children aged 20 and upward get older, they gradually observe a remarkable increase in their parents’ intelligence.
