Dr. Neubauer, it seemed, was careful to reduce the number of variables in his experimentation on Robert, Eddy, and David. Each child was place with a Jewish family that already had an older daughter so all three boys would have the same birth order family dynamics. But the doctor appeared to be curious about the socioeconomic factors that may impact the child’s development because he placed each of the three triplets in homes representing different economic classes. Robert was placed with an affluent family…his adoptive father was a doctor and his mother was a lawyer. Eddy was adopted by a middle-class family…his father was a teacher. David went to live with a blue collar family. The environment that the three boys were raised in varied greatly. David lived in a working-class area of Queens, while Robert grew up in well-to-do Scarsdale, and Eddy was raised in a suburb on Long Island.
