Questions & Answers

Q: How were genetics tracked over such a long period of time?

The study relied on genealogical records and predictions based on genetic models of transmission. Societies like the guil of one-name studies tracked people's genealogy over hundreds of years, providing valuable data.

Q: Are mothers and fathers equally influential in determining outcomes for children?

Yes, the study finds that mothers and fathers play the same role in terms of outcomes for their children, except for wealth. Fathers have a greater impact on wealth due to historical patterns of inheritance.

Q: Does birth order affect social outcomes?

Surprisingly, birth order does not significantly impact social outcomes, except for the oldest son in elite families who tends to inherit more wealth and have higher education opportunities.

Q: Does family size influence outcomes?

Family size has little impact on outcomes, except for wealth. Larger families from wealthy backgrounds tend to see a decline in wealth since it gets divided among more heirs.

Summary & Key Takeaways

  • The study examines 425,000 people in England over 400 years to understand how social status is inherited.

  • The research reveals a strong inheritance of social status, with no increase in social mobility over time.

  • Surprisingly, genetic correlation is a key factor in predicting the correlation between individuals, suggesting a simple model of genetic transmission.
