Finalman, R la twazyèm diminye : chèchè yo ta dwe chache diminye kantite patisipan yo nan eksperyans yo nan minimòm ki nesesè pou reyalize objektif syantifik yo. Nan eksperyans analòg, sa te rive natirèlman paske gwo depans varyab patisipan yo. Men, nan eksperyans dijital, patikilyèman moun ki gen pri varyab zewo, chèchè pa fè fas a yon kontrent pri sou gwosè a nan eksperyans yo, e sa gen potansyèl la pou mennen nan eksperyans san nesesite gwo.

Finally, the third R is reduce: researchers should seek to reduce the number of participants in their experiment to the minimum needed to achieve their scientific objective. In analog experiments, this happened naturally because of the high variable costs of participants. But in digital experiments, particularly those with zero variable cost, researchers don’t face a cost constraint on the size of their experiment, and this has the potential to lead to unnecessarily large experiments.
