An invited article in an award issue rather than a competitively submitted paper, which matters for how much independent scrutiny it received. Graded D as expert commentary, and retained because the archive's job includes recording what the strongest advocates say when pressed.

Concedes Sisk et al.'s r = .09 overall correlation but argues it is uninterpretable given I-squared of 96%, and counters with large-sample correlations of r = .24 to .34 with grades and with achievement tests among students facing adversity. Disputes the effect-size benchmark, noting that Hattie's own long-horizon effects average about .10, and invokes the argument that 0.10-0.15 SD is large for a brief cheap scalable intervention. On the EEF pilot it argues a non-significant +2 months is not evidence against the theory. It does not engage with the EEF effectiveness trial, which reported exact zeros on national tests with 4,584 pupils. The most important concession is structural - heterogeneity is granted, and the retreat position is that mindset works in some contexts, not that it works.
