Claim LD09-SL-C06 (v1.0)

A comment on the preprint-productivity study shows that dating adoption to an author’s first flagged abstract can by itself create post-adoption gains: placebo flags gave mean effects of 0.37 and 0.30 against 0.36 in the replicated baseline; the original authors reply that the artefact is “real but bounded” and that the association persists in designs it cannot bias.
