The call to use larger sample sizes in psychological research has been around for decades, but only relatively recently have researchers substantially increased the number of people in their studies. Although this change is certainly a good thing, it is quite possible that the emphasis on large sample sizes impacts certainly people (e.g., researchers with limited funding and access to no or small participant pools) and research areas (e.g., programs of research aimed at hard-to-recruit samples) more than others. In this episode, we discuss whether this is an issue for the field. We also talk about whether we've gone far enough to increase the sample sizes in our research.
