The "you can't raise your IQ" view—often rooted in the idea that general intelligence (g) is largely fixed after childhood due to high heritability (50–80% in adults)—has been a dominant narrative in psychology for decades. It stems from early figures like Arthur Jensen and Hans Eysenck, who argued that interventions like cognitive training yield only task-specific gains (near-transfer) without boosting broader IQ or g. This skepticism persists in some circles, emphasizing that IQ tests measure stable traits and that "brain training" apps are overhyped marketing.
However, the trend in scholarship over the last decade (2015–2025) has shifted toward a more optimistic, nuanced consensus: IQ can be raised modestly through targeted interventions, especially in adults, though gains are not unlimited and depend on the method. This evolution is driven by larger datasets, better experimental designs (e.g., RCTs with active controls), and meta-analyses distinguishing between short-term score boosts and lasting cognitive enhancements. While heritability limits dramatic changes, environmental levers like education, exercise, and multi-domain training demonstrably add 1–5+ IQ points per year of effort, with effects persisting across the lifespan.
