The Man at the Table
The evolutionary psychologist Gad Saad has a favorite classroom ritual. He ran through it again on a podcast not long ago. When he teaches at Concordia University, he asks his students to name the strongest predictor of child abuse in a home. The first answer is usually an absent parent. Then come the rest: alcoholism, poverty, a parent who was beaten as a child. He writes the answers on the board and calls them all reasonable. Then he tells the class that none of them is right. The number one predictor, he says, is a stepparent, and the effect is a hundredfold, a ratio he describes as astronomically larger than anything science ordinarily publishes. He reports getting goosebumps every time he tells it.
