Environmental Influences on Intelligence

Environmental factors such as good nutrition, supportive parenting, quality schools, and stable neighborhoods significantly influence intelligence.

These factors enrich the children's environment, enhancing academic performance and developing essential workplace skills.

Additionally, children from lower socioeconomic backgrounds adopted into economically advantaged families have higher IQs than their biological parents.

A study involving over 37,000 children identified four critical environmental interventions that effectively increase early childhood IQ.

A daily 1,000 mg omega-3 supplement during pregnancy or in infant formula can later raise a child's IQ by over 3.5 points.

Early educational interventions focused on complex task training raise the IQs of economically disadvantaged children by over 4 points.

Interactive reading, where parents ask open-ended questions, encourage children to read, and actively discuss the material, is associated with an increase in the child's IQ by over 6 points.

Attending a preschool program emphasizing language development increases IQ by over 4 points and up to 7 points for economically disadvantaged children.
