What do the twin studies tell us about the nature versus nurture argument?
Twin studies used to be almost the only way to compare the influence of genes against the environment on personality and behavior. Recent advances in genetics, however, suggest that opposing “nature” to “nurture” is misleading. Genes combine with the environment to produce complex human traits.
What is the criticism of the twin studies?
Critics of twin studies argue that they are based on false or questionable assumptions, including that monozygotic twins share 100% of their genes and the equal environments assumption.
How do twin studies support refute the nature nurture debate?
The traditional way of studying nature versus nurture relies on twins. Because identical twins share the same genetic code, comparing the health of twins can help determine whether genetic or environmental factors play more of a role in their health.
What are some issues with traditional twin studies?

Why are twin studies important and what controversies are tied to the findings?
We study twins to understand how much of the difference in a trait between people is caused by genes and how much is caused by the environment. These studies are important because they help scientists quantify genetic and modifiable environmental factors that increase the risk of certain diseases.
Why are identical twins useful in studying the influences of heredity and environment?
Twins and siblings can help us understand whether people are different because of genetic differences or because they live in different environments. Identical twins share the same genes, while non-identical twins share, on average, half of their genes with the other twin.
What does research say about the effects of both nature and nurture on intelligence?
