One of Diederik Stapel‘s many scholarly studies that have been retracted was, apparently, the only published scholarly study that included the phrase “compared to being primed with a dwarf.” The study itself is now one of the few scholarly studies to both (a) fixate on Santa Claus’s attributes and (b) be retracted.
The Retraction Watch blog has been covering the Stapel story with spirit and diligence. This is how Retraction Watch describes the Santa-Claus-attributes-/-dwarf paper retraction:
Diederik Stapel notches retractions 29, 30, and 31
… The following article from the European Journal of Social Psychology, “Staff, miter, book, share: how attributes of Saint Nicholas induce normative behavior” by Janneke F. Joly and Diederik A. Stapel, published online on 14 January 2008 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the co-author, the journal Editor in Chief, Tom Postmes, and John Wiley and Sons Ltd. The retraction has been agreed upon following the results of an investigation into the work of Diederik A. Stapel (https://www.commissielevelt.nl/). The Levelt Committee has determined that this article contained data that were fabricated by Diederik A. Stapel. His co-author was unaware of his actions and not in any way involved.
A copy of the Santa Claus / dwarf paper is available elsewhere online (or was, anyway, at the moment this blog item — the one you are reading — was being published).
