“The SMPY data supported the idea of accelerating fast learners by allowing them to skip school grades.

In a comparison of children who bypassed a grade with a control group of similarly smart children who didn’t, the grade-skippers were 60% more likely to earn doctorates or patents and more than twice as likely to get a PhD in a STEM field.”

The Study of Mathematically Precocious Youth (SMPY) is a prospective longitudinal survey study of persons (mostly in the United States) identified by scores of 700 or higher on a section of the SAT Reasoning Test before age 13 years. It is one of the longest-running longitudinal studies of gifted youth in world history. Study scholars have used survey data from study participants to advance hypotheses about talent development and occupational preferences. (wikipedia)

Lefties earn 10-12 percent less than righties do

We can explained it by their lower ability to lear and problem solve.

Sartarelli recruited 432 people, eight percent left-handers, to play a game. They had to put in effort and cut good deals. Some participants offered employment contracts to other participants. They played the roles of the “workforce” in the simulation.

The lefties achieved the same scores as the right-handers. They also brought home as much bacon in the simulation.

Researchers found some interesting relationships between the personality of left-handers and their performance.. They earned more when more extraverted, and less when more neurotic. At the same time, a 10 times bigger group of righties didn’t show this linking.

They also found that left-handers were more agreeable. Researchers connect these findings with lower salaries.
