A recent study found that genetics play a bigger role in future success than upbringing. IQ at age 23 was strongly connected to socioeconomic status by age 27.

Researchers from the German TwinLife project studied over 880 people, including identical and fraternal twins. They wanted to know how much of their differences came from genetics versus environment. The participants took IQ tests at age 23 and four years later, researchers evaluated their socioeconomic status by looking at factors like education level, occupation, and income. The results were striking - the link between IQ and socioeconomic status was largely explained by genetics, ranging from 69% to 98%. This means that your DNA may predict your future success more than your upbringing alone.

The study's findings challenge the idea that success mainly comes from growing up in a wealthy or highly educated family. Instead, it suggests that inherited traits may shape how people respond to opportunities, education, and life experiences.

The research also raises questions about social mobility and public policy. If genetics strongly influence life outcomes, can educational programs and social interventions really change a person's long-term trajectory? The study shows that we are born with different genetic predispositions and it is difficult to bring about long-term change in this regard through policy measures.

Why It Matters

This study's findings may encourage young adults to pursue the things they naturally enjoy and excel at, rather than focusing only on maximizing status or income. It also highlights the importance of considering genetic factors when examining life outcomes.
