Question

Quizplus · Accepted Answer

Research has shown that children from smaller families tend to have higher IQ scores than children from larger families. This is known as the "resource dilution hypothesis," which suggests that as family size increases, there are fewer resources (such as time, attention, and financial resources) to go around, leading to lower cognitive development in children. While there have been some positive correlations found, the overall trend is towards smaller family size being associated with higher IQ scores.
