Abstract (AI)
In the context of current concerns about replication in psychological science, we describe 10 findings from behavioral genetic research that have replicated robustly. These are "big" findings, both in terms of effect size and potential impact on psychological science, such as linearly increasing heritability of intelligence from infancy (20%) through adulthood (60%). Four of our top 10 findings involve the environment, discoveries that could have been found only with genetically sensitive research designs. We also consider reasons specific to behavioral genetics that might explain why these findings replicate.
Key Findings
1
Four of the 10 replicated findings concern environmental influences and were discoverable only through genetically sensitive research designs.
2
Intelligence heritability increases linearly from approximately 20% in infancy to 60% in adulthood.
3
The findings are considered major because of their substantial effect sizes and potential impact on psychological science.
4
The paper examines behavioral-genetics-specific factors that may contribute to the robust replication of these findings.
5
The paper identifies 10 behavioral-genetic findings that have replicated robustly despite broader replication concerns in psychological science.
Research Object
Ten robustly replicated findings in behavioral genetics
Research Subject
the magnitude, developmental patterns, environmental influences, and replicability of genetic and environmental effects on psychological traits, especially intelligence heritability
