Yes, the choice of replication sample size in the OSC was strange. Lakens and I made a similar point here: github.com/richarddmore... (unpublished manuscript). The gist is that 1) under OSC conditions it would be nearly impossible to tell if two studies are "similar" and 2) you're >

It's distinct, but our model here effectively (I think) would find (finds?) the same phenomenon. When we calculate magnitude error, we code in the typical signing of effects such that it's expected to see declines even in the absence of poor scientific behavior.

New draft: "Decline effects, statistical artifacts, and a meta-analytic paradox". In this manuscript I show how a common practice in meta-analysis (eg the 2015 Open Science Collaboration) creates artifactual signatures of poor scientific behavior. PDF: raw.githubusercontent.com/richarddmore... 1/x
The decline effect (Protzko & Schooler, 2017) is an observed phenomenon where effect sizes in experiments apparently diminish in size from the first paper demonstrating the effect to later replications. This has been taken as a symptom of an unhealthy scientific ecosystem, possibly caused by the "winner's curse" (selection on significance and regression to the mean), publication bias or opportunistic analyses. I show that decline effects can arise as an artifact from a much simpler source: the original article determining the sign of the effect in a meta-analysis. Moreover, such artifactual decline effects will show correlations with some of the same experimental properties that one would expect from biases from poor behavior, such as the sample size of the original study.

Recurring Crises in Psychology

"The current responses to the replication crisis, although valuable, are not ultimate solutions because they deflect fundamental questions and postpone the reconsideration of the ideals of psychology as a science."

Open Access: doi.org/10.1177/1089...
The replication crisis shook the discipline of psychology and has led to reforms such as open science and large-scale replication projects. Yet, it is not psychology’s first crisis, and it is likely not the last. In this paper, we look at three major crisis discussions in the history of psychology: discussions in the early 20th century about the possibility of psychology as a natural-scientific discipline; discussions in the 1960s–70s about the methods, relevance and scientific status of the discipline; and discussions in the 2010s about replication. We compare these crises to determine what generates crisis discussions in psychology and how they tend to unfold and be resolved. We argue that, despite differences across these crisis discussions, some fundamental questions about the object of research and proper methods of psychology recur, as do considerations related to epistemology, ontology, ethics and politics. Our analysis indicates that the current responses to the replication crisis, although valuable, are not ultimate solutions because they deflect fundamental questions and postpone the reconsideration of the ideals of psychology as a science.

After a provocation from Todd Kashdan I wrote up some frustrations I have with "wellbeing science", specifically the idea that it was born with life satisfaction scales.

I think this belief is untrue and unhelpful.

It’s a great study, and I’m excited to see this entering public awareness! But there’s still much more to cover, as BOLD coincides with other metabolic changes, including anaerobic metabolism and lactic acid production. In fact, others have proposed ↑CBF may help regulate local pH homeostasis.
