What does heritability indicate in relation to intelligence?

• A. The environmental factors influencing intelligence
• B. The genetic contribution to intelligence variation among individuals
• C. The socio-cultural limitations on intelligence development
• D. The effects of education on intelligence scores

Answer: (B)

Heritability refers to the proportion of variation in a trait, such as intelligence, that can be attributed to genetic factors within a particular population. When discussing intelligence, heritability estimates suggest the degree to which individual differences in intelligence scores can be explained by genetic differences among individuals. This means that if a population has a high heritability score for intelligence, a significant part of the differences in IQ scores can be understood through genetics rather than environmental factors. This concept does not address environmental influences on intelligence, as indicated in other options. While factors like education and socio-cultural elements can significantly impact intelligence development, heritability specifically focuses on the genetic contributions to the observed variation. Therefore, selecting the understanding of genetic contribution clarifies the importance of heritability in the realm of psychology and intelligence research.
