If it does raise it, estimate how much the rise would be?], 60-70% chance, "If it does raise the score, the estimated increase is modest, typically 3-8 points overall, with potentially larger gains (up to 5-10 points) in verbal IQ subscores. This is based on practice and education effects observed in cognitive training studies, though exact figures for grammar alone are scarce and vary by study. Sustained effort over years (e.g., through reading or language education) yields more noticeable changes than short-term training."

If it does raise it, estimate how much the rise would be?]: "I'd estimate a 60-80% probability of some measurable increase in scores, as causal links have been observed in controlled twin studies for reading (a closely related skill), but direct evidence for writing alone is more correlational than definitive. If it does raise scores, the increase is typically small and gradual, often in the range of 3-8 IQ points over time with consistent effort. This is inferred from effect sizes in literacy research."
