Face stimuli are commonly created in non-reproducible ways. In this paper, we document the irreproducibility of much existing work on faces, explain the benefits of reproducible stimuli, and introduce the open-source R package webmorphR. We explain the technical processes of morphing and transforming through a case study of creating face stimuli from an open-access image set. Finally, we discuss some ethical and methodological issues around the use of face images in research that may be ameliorated through the use of reproducible stimuli.
