[113] Data Litigada: Thank You (And An Update)

Posted on September 1, 2023August 31, 2023 by Uri, Joe, & Leif

Thank You A few months ago we reported evidence of data tampering in four papers that have since been retracted (or re-retracted) (Colada[109] .htm). A few weeks ago we were sued for doing so (Vox .htm). Lawsuits can be very expensive, and a thoughtful and generous group of colleagues and supporters started a fundraising campaign…

This is the introduction to a four-part series of posts detailing evidence of fraud in four academic papers co-authored by Harvard Business School Professor Francesca Gino.

[106] Meaningless Means #2: The Average Effect of Nudging in Academic Publications is 8.7%

Posted on November 29, 2022November 29, 2022 by Uri, Joe, & Leif

This post is the second in a series (.htm) in which we argue that meta-analytic means are often meaningless, because these averages (1) include invalid tests of the meta-analytic research question, and (2) aggregate incommensurable results. In each post we showcase examples of (1) and (2) in a different published meta-analysis. We seek out meta-analyses…

Posted on November 1, 2022November 2, 2022 by Uri, Joe, & Leif

This post is an introduction to a series of posts about meta-analysis [1]. We think that many, perhaps most, meta-analyses in the behavioral sciences are invalid. In this introductory post, we make that case with arguments. In subsequent posts, we will make that case by presenting examples taken from published meta-analyses. We have recently written…

[93] ResearchBox: Open Research Made Easy

Posted on October 30, 2020October 30, 2020 by Uri, Joe, & Leif

This post introduces ResearchBox, a new platform for easily sharing data, code, materials, and pre-registrations. With a design and approach similar to AsPredicted, ResearchBox simplifies, standardizes, and organizes supporting materials for publishable research.
