There is no established evidence that wealthy adults share an innate brain structure or a fixed “rich mindset.” The brain finding often invoked in this discussion concerns family income and brain surface area among children, adolescents, and young adults—not the brains of wealthy adults. It reports an association, not proof that income causes a difference or that wealth rewires the brain.
What the exact-title feature is about
The exact-title phrase comes from a Rolling Stone feature by Alex Morris published June 15, 2025. Its accessible Apple Podcasts listing frames the piece around how people with ambitions involving Mars, transhumanism, and superhuman AI come to think that way, and what their outlook could mean for others. The listing does not provide the feature’s full text, so its detailed arguments and any interviews should not be inferred from the synopsis.
What the brain study actually examined
A 2015 Forbes report summarized a study led by Kimberly Noble and Elizabeth Sowell that imaged 1,099 children, adolescents, and young adults in the United States. As Forbes described it, the researchers found an association between family income and brain surface area. The study population and exposure matter: it examined young people and family circumstances, not a representative group of wealthy adults and their personal net worth.
Forbes reported that children from families earning under US$25,000 per year had 6% lower brain surface area, on average, than children from families earning US$150,000 or more. This is a group comparison reported by secondary coverage, not a diagnostic measure for any child and not evidence that income alone caused the difference. The same report described the relationship as logarithmic: comparable income increments corresponded to relatively larger surface-area differences at the lower end of the income range than at the higher end.
#1 Best Overall
Forbes said the regions with the strongest associations supported language, reading, executive functions, and spatial skills. That does not establish that wealth produces superior abilities in those areas, or that an individual’s abilities can be read from family income. The primary study’s detailed methods and limitations are not established by the accessible secondary report, so the numerical findings should be understood with that qualification.
Why “hardwired differently” overstates the evidence
“Hardwired” suggests an innate, fixed, or uniform trait. The reported finding does not demonstrate any of those things. It concerns an association during development, and cannot show whether income itself caused the observed differences, whether other circumstances contributed, or how a particular person’s brain develops over time.
Rank #2
It is also a category error to treat family income during childhood, adult wealth, and socioeconomic status as interchangeable. A broad claim that rich people think differently would need evidence directly measuring wealthy adults, clearly defining wealth, and measuring the relevant features of thinking or brain function. The evidence summarized here does not do that. A related article using the phrase “Why rich people think differently” makes broad claims without identifying supporting studies in its accessible text; it is not a sound basis for claims about superior focus, grit, reward circuitry, or brain connectivity.
Possible pathways are not proven causes
The Forbes report said researchers did not know the mechanism behind the income–surface-area association. It discussed stressful home environments, nutrition, and pollution as possible pathways. These are hypotheses, not demonstrated explanations for the reported difference. The evidence summarized here cannot determine the contribution of any one factor.

Brain-imaging findings of this kind do not provide a shortcut for judging financial decisions, predicting someone’s earning potential, or explaining why a wealthy person holds an ambitious technological vision. They are not a prescription for building wealth, and they do not show that wealth itself makes people more intelligent or better decision-makers. The responsible takeaway is narrower: researchers reported a population-level association between family income and brain surface area during youth, while its causes and implications for any individual remain unsettled.
