Syntes: Oppenheimer & Ellefson (2024) — Urry et al. as a failure to generalise, not to replicate

Content

• Co-author of the original longhand-advantage study argues that Urry et al. 2021 differed in population, research setting, research team and fidelity (classroom project, undergraduate experimenters not fully trained, sessions with distractions and errors, different baseline laptop use), so it is better read as a generalisation attempt.
• Mechanism argument: distraction adds extraneous load, which should disrupt effortful longhand summarising more than verbatim typing — so the null fits the original account rather than refuting it.
• Notes that Urry's mini-meta is null while Allen et al. 2020 (14 studies) and Flanigan et al. 2024 (24 studies), mostly controlled settings, find a longhand advantage. Concedes the Urry conditions have more ecological validity and that the finding "may not generalize beyond distraction-free environments".

Role for C7

Steelman for C7 in the 2026-10-07 weaken (reason the kill was withheld) and the basis for phrasing the new bound as "not robust across settings" rather than "absent".
