Synopsis

In this 2021 opinion piece, Katharine Stevens argues that a classic logical error—“faulty generalization”—is distorting early-childhood policy. Policymakers and advocates repeatedly cite Heckman’s famous 13% return figure as proof that “high-quality early education” broadly pays off. In reality, Heckman’s calculations apply only to two exceptional, small-scale, intensive research programs from the 1960s–70s (Perry and Abecedarian, together ~115 children). Most current programs do not replicate those conditions, so the 13% claim does not automatically transfer. The article urges a wider evidence base and more targeted, intensive approaches for the children who need them most, rather than assuming broad expansion will deliver the same results.
