One year after publishing "False-Positive Psychology," we propose a simple implementation of disclosure that requires but 21 words to achieve full transparency. This article is written in a casual tone. It includes phone-taken pictures of milk-jars and references to ice-cream and sardines

Several researchers have relied on, or advocated for, internal meta-analysis, which involves statistically aggregating multiple studies in a paper to assess their overall evidential value. Advocates of internal meta-analysis argue that it provides an efficient approach to increasing statistical...

Empirical results often hinge on data analytic decisions that are simultaneously defensible, arbitrary, and motivated. To mitigate this problem we introduce Specification-Curve Analysis, which consists of three steps: (i) identifying the set of theoretically justified, statistically valid, and...

When studies examine true effects, they generate right-skewed p-curves, distributions of statistically significant results with more low (.01s) than high (.04s) p-values. What else can cause a right-skewed p-curve? First, we consider the possibility that researchers report only the smallest...

Journals tend to publish only statistically significant evidence, creating a scientific record that markedly overstates the size of effects. We provide a new tool that corrects for this bias without requiring access to nonsignificant results. It capitalizes on the fact that the distribution of...

We revisit a recent failure-to-replicate the finding that arbitrary anchors influence monetary valuations. Though in the replication the point estimate is indeed not significantly different from zero, it is also not significantly different from a sizable effect. This is partially explained by a...

Because scientists tend to report only studies (publication bias) or analyses (p-hacking) that “work”, readers must ask, “Are these effects true, or do they merely reflect selective reporting?” We introduce p-curve as a way to answer this question. P-curve is the distribution of...

Although researchers have documented many instances of crowd wisdom, it is important to know whether some kinds of judgments may lead the crowd astray, whether crowds’ judgments improve with feedback over time, and whether crowds’ judgments can be improved by changing the way judgments are...

Increasing accuracy motivation (e.g., by providing monetary incentives for accuracy) often fails to increase adjustment away from provided anchors, a result that has led researchers to conclude that people do not effortfully adjust away from such anchors. We challenge this conclusion. First, we...
