German researchers say that success is hereditary — or at least the willingness to take risks and the willingness to trust other people runs in families. And along the way they discovered that likes, not opposites attract.

Parents shape the character of their offspring, who in turn prefer to choose a partner similar to themselves. These two effects could contribute to attitudes such as willingness to take risks and confidence in others being “inherited” across several generations. At the same time these character traits are decisive, among other factors, for economic success. “Every economic decision is risky, whether it is about buying shares, building a house or just starting to study at university,” Armin Falk emphasises. “On the other hand success in business also involves the right amount of trust.”
