Researchers found that IQ, which is largely genetically influenced, strongly predicts education, career, and income. Even twins raised in the same household diverged based on genetic differences. The findings hint that life outcomes may be more hardwired than many people expect.

Researchers found that IQ measured at age 23 was strongly connected to socioeconomic status by age 27, including education, occupation, and income. According to the study, much of that connection appears to be tied to genetics rather than upbringing alone. The findings come from the German TwinLife project, a long term research effort designed to examine how genes and environment shape people's lives over time. Twin Study Explores IQ and Life Outcomes The research followed about 880 people, including both identical and fraternal twins. Roughly half of the participants were identical twins, who share all of their genes, while the others were fraternal twins, who share about half. Because the twins were raised in the same households, researchers could compare how much of the differences between them came from genetics versus environment. The participants took IQ tests at age 23. Four years later, researchers evaluated their socioeconomic status by looking at factors such as education level, occupation, and in
