Question 1

What are Turkheimers three laws of behaviour genetics?

Answer 1

3. A substantial portion of the variation in complex human behavioral traits is not accounted for by the effects of genes or families

Question 2

Why is it difficult to study human developmental social science?

Answer 2

1. Because behaviour emerges out of complex, nonlinear developmental processes
2. Ethical considerations prevent us from bringing most human developmental processes under effective experimental control
