  Preregistration refers to the practice of specifying what you are going to
do, and what you expect to find in your study, before carrying out the study.
This practice is increasingly common in medicine and psychology, but is rarely
discussed in NLP. This paper discusses preregistration in more detail, explores
how NLP researchers could preregister their work, and presents several
preregistration questions for different kinds of studies. Finally, we argue in
favour of registered reports, which could provide firmer grounds for slow
science in NLP research. The goal of this paper is to elicit a discussion in
the NLP community, which we hope to synthesise into a general NLP
preregistration form in future research.
