The first, based on SMPY data, displays odds ratios for various accomplishments (doctorate degree, STEM publication, patent, high income, tenure) as a function of SAT-M score at age 13. The quartiles correspond roughly to 1 in 200 ability (Q1) to 1 in 10k ability (Q4). This data soundly refutes the "IQ above 120 doesn't matter" Malcolm Gladwell nonsense. See earlier post Horsepower matters; Psychometrics works.
In (imprecise) words: "Profoundly gifted children are 10+ times more likely than merely gifted children to, e.g., earn a patent or gain tenure at a top research university. They are at least several times more likely to earn exceptionally high incomes." (Note "merely gifted" is somewhat below the Q1 SMPY cut -- most school systems use top few percent vs top 0.5 percent.)
The second figure shows regression coefficients of income (at various ages) vs IQ and personality traits (standardized, so returns for each SD of trait). This was originally discussed in Earnings effects of personality, education and IQ for the gifted; see also this paper (Miriam Gensowski, Copenhagen). Note the IQ returns may be underestimated for average individuals since the data source is Terman and there is significant restriction of range (everyone tested at better than 1 in 200 or so on the Stanford-Binet). Nevertheless there are still positive returns to above average IQ within the Terman group (analogous to SMPY results above).
