Psychologists must be able to test both for the presence of an effect and absence effect. In addition testing against zero, researchers can use two one-sided tests (TOST) procedure equivalence reject a smallest size interest (SESOI). The TOST used determine if observed is surprisingly small, given that true at least as extreme SESOI exists. We explain range approaches in psychological science provide detailed examples how should performed reported. Equivalence are important extension...
Replication—an important, uncommon, and misunderstood practice—is gaining appreciation in psychology. Achieving replicability is important for making research progress. If findings are not replicable, then prediction theory development stifled. interrogation of their meaning validity can advance knowledge.

Selectively publishing results that support the tested hypotheses (“positive” results) distorts available evidence for scientific claims. For past decade, psychological scientists have been increasingly concerned about degree of such distortion in their literature. A new publication format has developed to prevent selective reporting: In Registered Reports (RRs), peer review and decision publish take place before are known. We compared published RRs ( N = 71 as November 2018) with a random...
For almost half a century, Paul Meehl educated psychologists about how the mindless use of null-hypothesis significance tests made research on theories in social sciences basically uninterpretable. In response to replication crisis, reforms psychology have focused formalizing procedures for testing hypotheses. These were necessary and influential. However, as an unexpected consequence, psychological scientists begun realize that they may not be ready test Forcing researchers prematurely...
Researchers often conclude an effect is absent when a null-hypothesis significance test yields nonsignificant p value. However, it neither logically nor statistically correct to hypothesis not significant. We present two methods evaluate the presence or absence of effects: Equivalence testing (based on frequentist statistics) and Bayes factors Bayesian statistics). In four examples from gerontology literature, we illustrate different ways specify alternative models that can be used reject...

Abstract Psychology's replication crisis is typically conceptualized as the insight that published literature contains a worrying amount of unreplicable, false‐positive findings. At same time, meta‐scientific attempts to assess in more detail have reported substantial difficulties identifying unambiguous definitions scientific claims articles and determining how they are connected presented evidence. I argue most so critically underspecified empirically evaluate them doomed failure—they not...
The use of journal impact factors and other metric indicators research productivity, such as the h-index, has been heavily criticized for being invalid assessment individual researchers fueling a detrimental “publish or perish” culture. Multiple initiatives call developing alternatives to existing metrics that better reflect quality (instead quantity) in assessment. This report, written by task force established German Psychological Society, proposes how responsible could be done field...

Meta-analyses are an important tool to evaluate the literature. It is essential that meta-analyses can easily be reproduced allow researchers impact of subjective choices on meta-analytic effect sizes, but also update as new data comes in, or novel statistical techniques (for example correct for publication bias) developed. Research in medicine has revealed often cannot reproduced. In this project, we examined reproducibility psychology by reproducing twenty published meta-analyses....

Providing access to research data collected as part of scientific publications and publicly funded projects is now regarded a central aspect an open transparent practice increasingly being called for by funding institutions journals. To this end, researchers should strive comply with the so-called FAIR principles (of management), that is, be findable, accessible, interoperable, reusable. Systematic management supports these goals and, at same time, makes it possible achieve them efficiently....
Social science has a ‘context sensitivity’ problem: the people that we study, and situations they engage in, are so complex variable predicting how will think, feel, behave in given situation is very challenging. Even when able to make such predictions, it often unclear accurate be if some feature of studied subjects and/or changes. This limits utility our research for application policy, as ‘contextual factors’ might change conclusions unknown. It time address this context sensitivity...
In a summary of recent discussions about the role direct replications in psychological science, Zwaan, Etz, Lucas, and Donnellan (2017; henceforth ZELD) argue that should be more mainstream, discuss six common objections to replication studies. We believe debate importance research is essentially driven by disagreements value studies best way allocate limited resources. suggest decision theory framework (Wald, 1950) can provide tool for researchers (a) evaluate costs benefits order determine...

Präambel: Viele Diskussionspunkte um Open Data lassen sich grob in zwei Perspektiven einteilen. (A) die Qualitätsperspektive, bzw. Gemeinwohlperspektive: Wie können wir gute Wissenschaft machen und echtes Wissen generieren? Was aus der aktuellen Replikationskrise lernen Zukunft besser machen? Die andere Perspektive könnte man als (B) individuell-strategische bezeichnen: bedeuten neuen Forschungspraktiken -anforderungen für individuellen Karrieren von Forscherinnen Forschern, insbesondere dem...
