Preregistration Distinguishes Between Exploratory and Confirmatory Research? Previous justifications for preregistration have focused on the distinction between “exploratory” and “confirmatory” research. However, as I discuss in this recent presentation, this distinction faces unresolved questions. For example, the distinction does not appear to have a formal definition in either statistical theory or the philosophy of science.

An often overlooked source of the “replication crisis” is the tendency to treat the replication study as a definitive verdict while ignoring the statistical uncertainty inherent in both the original and replication studies. This simplistic view fosters misleading dichotomies and erodes public trust in science.

A conference called “The promises and pitfalls of preregistration” was hosted by the Royal Society in London from 4th-5th March 2024. Here, I discuss the presentations by Chris Donkin and Stephan Lewandowsky, both of which consider some of the potential “pitfalls” of preregistration.

The Centre for Open Science’s symposium on “Critical Perspectives on the Metascience Reform Movement” took place on 7 ^th March 2024. It was organised by Sven Ulpts, and it includes presentations by Bart Penders, Tom Hostler, Stephan Guttinger, Sarahanne Field, Nicole Nelson, and Berna Devezer.

During multiple testing, researchers often adjust their alpha level to control the familywise error rate for a statistical inference about a joint union alternative hypothesis (e.g., “ H1 or H2 ”). However, in some cases, they do not make this inference.

The inflation of Type I error rates is thought to be one of the causes of the replication crisis. Questionable research practices such as p -hacking are thought to inflate Type I error rates above their nominal level, leading to unexpectedly high levels of false positives in the literature and, consequently, unexpectedly low replication rates. In this article, I offer an alternative view.

In an article published last week in Synthese, philosopher of science Pekka Syrjänen asked “does a theory become better confirmed if it fits data that was not used in its construction versus if it was specifically designed to fit the data?” The first approach is called prediction, and the second approach is called accommodation . The debate over the epistemic advantages of prediction and accommodation has been bubbling away for

Abstract Popper’s (1983, 2002) philosophy of science has enjoyed something of a renaissance in the wake of the replication crisis, offering a philosophical basis for the ensuing science reform movement. However, adherence to Popper’s approach may also be at least partly responsible for the sense of “crisis” that has developed following multiple unexpected replication failures.

An Intellectual Vocation In his book “The Soul of a University” (2018), Chris Brink describes the story of G.H. Hardy, a Cambridge Mathematician whose principled stance on his academic research was that it had no practical use whatsoever: “No discovery of mine” Hardy proudly wrote, “has made, or is likely to make, directly or indirectly, for good or ill, the least difference to the amenity of the world”

Felipe Romero presented his work - “The conceptual origins of metascience: Fashion or revolution?” - in The Popper Seminar at the London School of Economics on 30th May 2023. Here, I highlight a few points that he raised and provide some comments along the way. ::: {#youtube2-AKWCCdK-jgc .youtube-wrap attrs=“{"videoId":"AKWCCdK-jgc","startTime":null,"endTime":null}” component-name=“Youtube2ToDOM”} Ein Fehler ist aufgetreten.

Abstract I discuss Van Drimmelen’s (2023) Metascience2023 presentation on researchers’ decision making during the research process.
