This paper argues that some of the discussion around meta-scientific issues can be viewed as an argument over different “meta-hypotheses” – assumptions made about how different hypotheses in a scientific literature relate to each other. I argue that, currently, such meta-hypotheses are typically left unstated except in methodological papers and that the consequence of this practice is that it is hard to determine what can be learned from a direct replication study. I argue in favor of a procedur...

Many researchers rely on meta-analysis to summarize research evidence. However, there is a concern that publication bias and selective reporting may lead to biased meta-analytic effect sizes. We compare the results of meta-analyses to large-scale preregistered replications in psychology carried out at multiple laboratories. The multiple-laboratory replications provide precisely estimated effect sizes that do not suffer from publication bias or selective reporting. We searched the literature and ...

The hypothesis that intuition promotes cooperation has attracted considerable attention. Although key results in this literature have failed to replicate in pre-registered studies, recent meta-analyses report an overall effect of intuition on cooperation. We address the question with a meta-analysis of 82 cooperation experiments, spanning four different types of intuition manipulations—time pressure, cognitive load, depletion, and induction—including 29,315 participants in total. We obtain a pos...

Abstract Many view preregistration as a promising way to improve research credibility. However, scholars have argued that using pre-analysis plans in Experimental Economics has limited benefits. This paper argues that preregistration of studies is likely to improve research credibility. I show that in a setting with selective reporting and low statistical power, effect sizes are highly inflated, and this translates into low reproducibility. Preregistering the original studies could avoid such in...

Many researchers rely on meta-analysis to summarize research evidence. However, recent replication projects in the behavioral sciences suggest that effect sizes of original studies are overestimated, and this overestimation is typically attributed to publication bias and selective reporting of scientific results. As the validity of meta-analyses depends on the primary studies, there is a concern that systematic overestimation of effect sizes may translate into biased meta-analytic effect sizes. ...

Heterogenous treatment effects make it difficult to extrapolate from one research setting to another. However, what appears to be differences in effects across subpopulations may simply be false positives. This paper uses a representative sample of the Norwegian population (N = 1390) to systematically test for several proposed sources of heterogeneity in the literature on intuitive prosociality – a literature with large variation in results, which some researchers claim results from heterogeneit...

Andrews & Kasy (2019) propose an approach for adjusting effect sizes in meta-analysis for publication bias. We use the Andrews-Kasy estimator to adjust the result of 15 meta-analyses and compare the adjusted results to 15 large-scale multiple labs replication studies estimating the same effects. The pre-registered replications provide precisely estimated effect sizes, which do not suffer from publication bias. The Andrews-Kasy approach leads to a moderate reduction of the inflated effect sizes i...

Many markets resemble repeated prisoner's dilemma situations with the possibilities for mutual partner choice. In this paper, we show experimentally that partner choice by mutual consent has a strong positive effect on cooperation. Mutual partner choice makes it possible to form long-lasting reciprocal partnerships. To understand partnership formation we also add a treatment where the participants could communicate with each other in a common chat room. Chat transcript reveals that promises are ...

Are humans intuitively cooperative, or does reflection foster cooperation? The Social Heuristics Hypothesis (SHH) proposes that intuition promotes cooperation, but the evidence is inconsistent across studies. We combine a lab experiment with a re-analysis of existing studies to test for an effect of time-pressure on cooperation. We suggest – based on a meta-study of about 12.000 subjects from lab and online experiments across the world - that time pressure only influences cooperation if subjects...
