Multiverse analysis, abdication of responsibility and manufacturing of doubt: I have written on some downsides I see with multiverse analysis (which I like in principle): arxiv.org/abs/2607.14623 I was inspired/provoked to write it by @dingdingpeng.the100.ci (thanks!)

Yannick Griep, a former rising star in management research at Radboud University in the Netherlands, is set to lose an undisclosed number of articles from a journal he once edited, Retraction Watch has learned.

Th resigning editors say the publisher’s decision to become fully open access is “irreconcilable with our vision of science.” According to the journal’s homepage, all submissions from July 1 that end up in the journal will be subject to a $2,990 article processing charge (APC).

Ian Hussey (@ianhussey.mmmdata.io) contacted me about the recurring problem of unusually large SMD values appearing in published meta-analyses. Very large SMDs can result from using SEs in place of SDs in their calculation, which is a mistake I have also seen in practice. 1/4
