It's true that sample sizes (N) in psychology research should be large. In fact, the whole of psychology, especially social psychology research, seems to be in a crisis regarding its credibility as a source of knowledge.

Any time a result is surprising, researchers will try to replicate it, to see if the phenomenon is dependable or just a fluke (a one-time occurrence). A replication study attempts to validate the findings of a prior piece of research. In the meantime, these findings remain immune to the replication controversy. Replication research, however, does not seem to have received favorable consideration over time by comparative psychologists. We replied, arguing that, since Bem's precognitive effect would be of such clear importance for psychology, it would surely be critical to check whether it exists in the first place, before going on to look at it in different contexts. Psychology's replication drive: it's not about you. Following is a brief summary of some of these issues, with an emphasis on how they might affect students and early career researchers.

For this purpose, replication - one of the main principles of science - is particularly welcome in comparative psychology, especially when dealing with exotic species. This value underlies Steiger's (1990, p. 176) dictum that an ounce of replication is worth a ton of inferential statistics, an attitude shared by Moonsinghe, Khoury, and Janssens (2007). One of the outcomes of the so-called "replication crisis" is that large samples are more and more important in psychology. Start studying Psychology: Scientific Method.

When studies are replicated and achieve the same or similar results as the original study, it gives greater validity to the findings. So, again, not so much incentive to hoard data or lab procedures. Why is random sampling important in psychology? Replication is an important part of the scientific process because it can help to establish the external validity of knowledge and thus the ability to generalize a study's findings more broadly. Another important reason, one of the most important in my view, is that psychology experiments are often technically very easy to replicate, and the advent of MTURK made it possible to replicate them with considerably more participants and lower cost than the original studies required. In two experiments involving 356 participants, we recreated Przybylski and Weinstein's original work.
