Late Bloomer Offending Patterns: Towards a Harder Empirical Definition—Commentary on Matsuda et al. (2022)

Abstract Matsuda et al. (2022) show that late bloomers also exist in self-report data. They use a “dynamic” definition of bloomer offending pattern as they have concerns with definitions based on arbitrary age cutoff points. But the approach does not make groups less than hard definitions. In this commentary, I argue has important advantages and demonstrates an alternative using while exploring heterogeneity within onset group.
