Growing up as somebody's daughter, it is sometimes hard to observe who your parent is, as a person in the world. However, as you grow up, and become an adult yourself, one can reflect back and see a more balanced picture of the person who raised you. My father is someone dedicated to his profession, to his students, to the idea that he could make a difference in the world. He was able to look at theories, statistical tables, and formulas, and to study children with learning disorders, and then somehow evaluate and synthesize the information in a unique way so that the field of intelligence would be forever enriched and changed for his having entered it.

He is a man capable of great love. He met his wife, Nadeen, when they were both teenagers. Their love would solidify over the years and transcend a number of life events that might have separated many others. They provided comfort to each other as life partners and intellectual collaboration as working partners. Their specialties and thought processes intertwined to create the long list of tests enumerated in this book. Nadeen worked with him and they processed their thoughts and ideas 24/7 in a thriving atmosphere for their creative and brilliant minds.

The idea of what is just, or justice, has been an important idea for my father. This idea, combined with the knowledge he has gained and synthesized in the field of IQ has led to many important accomplishments in the field of intelligence.
