Questionable Metascience PracticesIn this new article, I consider questionable research practices in the field of metascience. A questionable metascience practice (QMP) is a…Apr 25, 2023Apr 25, 2023
Exploratory hypothesis tests can be more compelling than confirmatory hypothesis testsResearchers often distinguish between:Aug 27, 2022Aug 27, 2022
One-Sided Significance TestsIn this paper (Rubin, 2022), I make two related points: (1) researchers should halve two-sided p values if they wish to use them to make…Apr 4, 2022Apr 4, 2022
What Type of Type I Error?In this paper (Rubin, 2021), I consider two types of Type I error probability. The Neyman-Pearson Type I error rate refers to the maximum…Jul 25, 2021Jul 25, 2021
Repeated Sampling from the Same Population?In this paper in the European Journal for Ph(Rubin, 2020), I consider Fisher’s criticism that the Neyman-Pearson approach to hypothesis…Jul 20, 2021Jul 20, 2021
An Evaluation of Four Solutions to the Garden of Forking Paths ProblemIn this paper (Rubin, 2017), I consider Gelman and Loken’s (2013, 2014) garden of forking paths problem. Forking paths occur when…Jul 20, 2021Jul 20, 2021
The Costs of HARKing: Does it Matter if Researchers Engage in Undisclosed Hypothesizing After the…I argue against the view that HARKing is problematic for scientific progress.Jul 12, 2021Jul 12, 2021
Does Preregistration Improve the Interpretablity and Credibility of Research Findings?Preregistration entails researchers registering their planned research hypotheses, methods, and analyses in a time-stamped document before…Jul 12, 2021Jul 12, 2021
When to Adjust Alpha During Multiple TestingIn this new paper, I consider when researchers should adjust their alpha level (significance threshold) during multiple testing.Jul 12, 2021Jul 12, 2021
