Gallus’s paper (online 30 September 2016; December 2017 issue) tested a noncash symbolic award among German Wikipedia newcomers already screened for constructive editing. Within this pool, award or no award was assigned by chance, like drawing lots. Excluding 110 accounts blocked after assignment left 1,617 awardees and 2,390 nonrecipients. In the following month, about 42 per 100 awardees versus 35 per 100 nonrecipients edited at least once. Per 100 scales each group’s share to a common hundred: about seven more returners per 100, not seven extra edits per account. Removing accounts after assignment may make groups less comparable. Return is not recruitment or scientific accuracy; later awards and community responses complicate longer-term attribution.
