grade Clongitudinalindependentreplicatednumbers spot-checked
Sample
1,636 participants plus a 478-participant replication sample
Population
SMPY cohorts (top 1% of quantitative ability), assessed at ~age 50.
Design
Longitudinal follow-up testing the standard social-emotional objection to acceleration. Same selection limits as the rest of the SMPY corpus, but for a NULL result those limits matter far less: the concern being tested predicts harm, and none appears.
Key findings
The social-emotional objection to academic acceleration has no empirical support at any measured horizon out to age 50. This is the rock-solid half of the SMPY acceleration record — the absence of harm, as distinct from the selection-fragile upside.
Genetic confound
Selection is a much weaker objection to a null than to a positive finding. If accelerated students were selected on resilience one would still expect SOME signal in a sample this size; there is none.
Replication notes
Internally replicated in a second sample.
