p-Hacking, the use of analytic techniques that may lead to distorted research results, is widely condemned on epistemic and practical grounds. The prevalent position on this questionable research practice is that p-hacking should be avoided because …
Running studies with high statistical power, while effect size estimates in psychology are often inaccurate, leads to a practical challenge when designing an experiment. This challenge can be addressed by performing sequential analyses while the data …
P. E. Meehl did first 10 sessions (Winter Quarter, Jan–Mar 1989). In the Spring Quarter, several other department members lectured on various topics. Then PEM did last two sessions (5/25/89 and 6/1/89).
In psychology, attempts to replicate published findings are less successful than expected. For properly powered studies replication rate should be around 80%, whereas in practice less than 40% of the studies selected from different areas of …
A study with low statistical power has a reduced chance of detecting a true effect, but it is less well appreciated that low power also reduces the likelihood that a statistically significant result reflects a true effect. Here, we show that the …
Recently, evidence for endemically low statistical power has cast neuroscience findings into doubt. If low statistical power plagues neuroscience, then this reduces confidence in the reported effects. However, if statistical power is not uniformly …
A challenge when interpreting replications is determining whether the results of a replication “successfully” replicate the original study. Looking for consistency between two studies is challenging because individual studies are susceptible to many …
A viewpoint published in Tourism Management articulates the potential benefits of preregistration and ‘debunking myths' surrounding this controversial open-science practice (Chen and Li, 2024). This rejoinder critically examines six key arguments …
