Psychological Research May Not Have Replication Crisis At All

The second point that Daniel Gilbert and colleagues pointed out is the power to carry out the experiments.

Given the potential errors stated above, it is valuable to conduct multiple replications to determine how much of the results of a single replication are achieved by chance. Because the OSC was not able to have that information, Nosek referred Gilbert's group to his other project, which is the "Many Labs" project (MLP).

The OSC replicated 100 studies for one time only. The result was an uninspired 47 percent successful replication.

MLP, however, replicated each of the studies 35 or 36 times. Such powerful technique yielded a whopping 85 percent successful replication.

The original paper, the one that only saw a 39% replication rate, was published in Science. You need a subscription to view the full paper, but there is a summary available here.
