Looking at IQ and learning if the level of intelligence has anything to do with success: Part 3 of 3

Using IQ as an indication of the odds of success may be measured from other comparisons besides race.

First—Let’s look at income (World Top Incomes Database; Real U.S. 2010 dollars):

Psychology reports, The average IQ of individuals in the top 1% who earned $857,477  was 137.  The next level was the top .1% with an average income of $3,693,111 and an average IQ of 149.  Then we have the top .01% earning on average $16,267,243 with an average IQ of 160.

The other 99 percent with an annual income range of $0 to $335,869 had IQ’s—on average—that ranged from 60 to 136.

Second—a few examples of the average IQ of college majors:

The average IQ of a Physics and Astronomy major was 133; Mathematics Sciences 130; Engineering 126; Chemistry 124; Humanities & Arts 120; Agriculture 115; Health and Medical Sciences 111; Education 110, and Social Work 103. For the complete list, I suggest you click on Statistics

Third—Number of billionaires by continent in US dollars:

Africa has 13 (population of 995 million—1 for every 76.5 million people)

Asia 412 (4.14 billion—1 for every 10.048 million)

Europe 390 (739 million—1 for every 1.89 million)

North America 486 (529 million—1 for every 1.088 million)

South America 51 (386 million—1 for every 7.56 million)

Four— Poverty and low IQ: says, “The effect of environment on the IQ of young children can be significant, particularly for children living in poverty. As the influence of poverty decreases, the importance of environmental conditions as a limiting factor on intelligence also decreases. By addressing the environmental issues created by poverty, it may be possible to weaken the link between low socioeconomic status and poor student performance on IQ (and other) tests.”

“A childhood spent in poverty often sets the stage for a lifetime of setbacks. Secure attachments and stable environments, so vitally important to the social and emotional development of young children, are often denied to our neediest kids. These children experience more stress due to loneliness, aggression, isolation, and deviance in their peer relationships, and they are more likely to describe feeling deprived, embarrassed, picked on, or bullied. As a result, they more often face future struggles in marital and other relationships.” ( says) says, “It is posited that low IQ children may be likely to engage in delinquent behavior because their poor verbal abilities limit their opportunities to obtain rewards in the school environment.”

Leading from the says, “Signs of poor EQ include the inability to listen to others, defensiveness, unawareness of how we come across, lack of sensitivity to others’ feelings, an inability to deal constructively with conflict, a drive to control others, narcissism, and the need to have our own way.”

Conclusion: The evidence suggests that average to high IQ—when a child lives in a middle income or higher environment with stable parents—does have a vital role to play in later success, but IQ by itself isn’t enough to predict outcomes.

It is also possible, but rare, for a child to escape poverty as an adult. The odds are also against children with IQ’s lower than average.

In the end—no matter the IQ; SQ; EQ or LDs—parent involvement is the key that overcomes almost all obstacles to a child’s education. A key study in the UK says:” Overall, research has consistently shown that parental involvement in children’s education does make a positive difference to pupils’ achievement.” (

Based on 49 studies, It is noted that the bulk of the research finds that a positive learning environment at home has a powerful impact on student achievement. The second approach is illustrated by Rhoda Becher’s extensive review of parent education literature, which finds numerous studies documenting effects of school-based programs that train low-income parents to work with their children. Effects include significantly improved language skills, test performance, and school behavior, as well as important effects on the general educational process. The third approach is illustrated by studies of community involvement which suggest that the degree of parent and community interest in high quality education is the critical factor in the impact of the school environment on the achievement and educational aspirations of students. (

When the parents are not part of the learning process; are dysfunctional and/or abusive, the odds are against success no matter what teachers do in the classroom.
