What is the relationship between socioeconomic status and IQ?
Our results suggest that family socioeconomic status (SES) impacts children’s development of intelligence from infancy through adolescence. Children of the highest and lowest SES backgrounds were on average separated by 6 IQ points at the age of 2 years. By the age of 16, the IQ gap had almost tripled (Fig. 2).

How does social status affect the brain?
Socioeconomic status (SES) has effects on cognition, academic achievement and mental health. Research on brain development enables us to identify the differences in the cognitive and affective neural systems that underlie the effects of SES on cognition, academic achievement and mental health.
Does poverty affect brain development?
A growing body of research now shows that poverty changes the way children’s brains develop, shrinking parts of the brain essential for memory, planning, and decision-making. Scientists are also tapping into the brain’s capacity for change, uncovering ways to reduce these effects.

IQ is moderately correlated with adult academic achievement, occupational attainment, and emotional and social adjustment, but the underlying causes of these findings are complex. Other traits including education, family influences, motivation, and practical intelligence also contribute substantially to life success.
What does research on IQ score show?
IQ scores are used for educational placement, assessment of intellectual disability, and evaluating job applicants. In research contexts, they have been studied as predictors of job performance and income.

What inequality does to the brain?
Our results were remarkably consistent across multiple studies. In general, children from more disadvantaged homes tended to perform more poorly on tasks that tested their language and memory skills and the ability to exert self-control and avoid distraction.
How does poverty affect you intellectually?
This has negative physical and psychological health consequences, along with reduced educational and professional attainment. Poverty increases the risk of mental illnesses, including schizophrenia, depression, anxiety and substance addiction.
How does poverty affect mindset?
In a 2013 study published in Science, researchers from the University of Warwick, Harvard, Princeton, and the University of British Columbia find that for poor individuals, working through a difficult financial problem produces a cognitive strain that’s equivalent to a 13-point deficit in IQ or a full night’s sleep …
