Do the failures of replication shake your faith in what you have learned about psychology? One response to this "replicability crisis" has been the emergence of open science practices . There were attempts at replication and most of them failed, but not all. After all, if scientists were only to publish safe results that were easy to replicate, we might have very boring studies that do not advance our knowledge very quickly. Why?

Psychology should take a critical look at common practices and adopt more conservative . The threshold for significance is traditionally a p-value of less than .05, although the replication crisis has led researchers to rethink relying on p-values or to propose changing the threshold for what counts as "significant" to a lower p-value (such as .005). For our part, psychologists also have a vested interest in ensuring that our methods and findings are as trustworthy as possible. "Feeling the future: experimental evidence for anomalous retroactive influences on cognition and affect.".

Does the Door-in-the-Face Technique Really Work?

Twenty of the 32 original studies with a P value of less than 0.001 could be replicated, for example, while just 2 of the 11 papers with a value greater than 0.04 were successfully replicated. Bem, DJ (March 2011). When findings are important enough to be published, they are often important enough to prompt further, more conclusive research. When researchers criticize others for being unable to replicate the original findings, saying that the conditions in the follow-up study were changed, this is important to pay attention to as well. This example of non-replication does not invalidate the original results. A large number of scientists have attempted to replicate studies on what might be called “metaphorical priming,” and more often than not these replications have failed. In recent years psychology has grappled with a failure to replicate research findings. Daniel Gilbert, a psychology professor at Harvard, wrote that certain so-called . Asch, S. E. (1956).

In 2011, Bem published an article claiming he had found in a number of studies that future events could influence the past. Their answers may, in fact, not be at all representative of the larger population. An examination of 21 findings published in top-tier journals found that two-thirds replicated successfully. The phrase was coined in the early 2010s as part of a growing awareness of the . This example of non-replication does not invalidate the original results. A traditional benchmark of statistical significance in psychology is a p-value of .05, though more stringent benchmarks have recently been proposed. Found insideReproducibility and Replicability in Science defines reproducibility and replicability and examines the factors that may lead to non-reproducibility and non-replicability in research. In this video, Ted Miguel discusses the Many Labs Project, a multi-institutional, collaborative replication project. A new article on mentorship in the sciences was recently retracted by the journal Nature Communications. People have the right to know if they can trust research evidence. As one can see from the examples, some of the studies that fail to replicate report extremely interesting findings—even counterintuitive findings that appear to offer new insights into the human mind. Scientists should be willing to consider unusual or risky hypotheses but ultimately allow good evidence to have the final say, not people’s opinions. It turns out that many studies in psychology—including many highly cited studies—do not replicate. The reward structure in academia has served to discourage replication. Nevertheless, psychologists interested in reform have pressed ahead with efforts to make the claims of psychological research more credible. We would recommend that laboratories conduct careful sets of interlocking studies, where important findings are followed up using various methods. Bem, DJ (March 2011). This is the first book to introduce the new statistics - effect sizes, confidence intervals, and meta-analysis - in an accessible way. If, for instance, you wanted to exactly replicate Asch’s (1956) classic findings on conformity, you would follow the original methodology: you would use only male participants, you would use groups of 8, and you would present the same stimuli (lines of differing lengths) in the same order.
