Powerpose update

I contacted Anna Dreber, one of the authors of the paper that failed to replicate power pose, and asked her about a particular question that came up regarding their replication study. One of the authors of the original power pose study wrote that the replication “varied methodologically in about a dozen ways — some of […] The post Powerpose update appeared first on Statistical Modeling, Causal Inference, and Social Science.

We fiddle while Rome burns:  p-value edition

Raghu Parthasarathy presents a wonderfully clear example of disastrous p-value-based reasoning that he saw in a conference presentation. Here’s Raghu: Consider, for example, some tumorous cells that we can treat with drugs 1 and 2, either alone or in combination. We can make measurements of growth under our various drug treatment conditions. Suppose our measurements […] The post We fiddle while Rome burns: p-value edition appeared first on Statistical Modeling,…

This is not news.

Anne Pier Salverda writes: I’m not sure if you’re keeping track of published failures to replicate the power posing effect, but this article came out earlier this month: “Embodied power, testosterone, and overconfidence as a causal pathway to risk-taking.” From the abstract: We were unable to replicate the findings of the original study and subsequently […] The post This is not news. appeared first on Statistical Modeling, Causal Inference, and…

Hark, hark! the p-value at heaven’s gate sings

Three different people pointed me to this post, in which food researcher and business school professor Brian Wansink advises Ph.D. students to “never say no”: When a research idea comes up, check it out, put some time into it and you might get some success. I like that advice and I agree with it. Or, […] The post Hark, hark! the p-value at heaven’s gate sings appeared first on Statistical…

What is valued by the Association for Psychological Science

Someone pointed me to this program of the forthcoming Association for Psychological Science conference: Kind of amazing that they asked Amy Cuddy to speak. Weren’t Dana Carney or Andy Yap available? What would really have been bold would have been for them to invite Eva Ranehill or Anna Dreber. Good stuff. The chair of the […] The post What is valued by the Association for Psychological Science appeared first on…

fMRI clusterf******

Several people pointed me to this paper by Anders Eklund, Thomas Nichols, and Hans Knutsson, which begins: Functional MRI (fMRI) is 25 years old, yet surprisingly its most common statistical methods have not been validated using real data. Here, we used resting-state fMRI data from 499 healthy controls to conduct 3 million task group analyses.

“Dear Major Textbook Publisher”:  A Rant

Dear Major Academic Publisher, You just sent me, unsolicited, an introductory statistics textbook that is 800 pages and weighs about 5 pounds. It’s the 3rd edition of a book by someone I’ve never heard of. That’s fine—a newcomer can write a good book. The real problem is that the book is crap. It’s just the […] The post “Dear Major Textbook Publisher”: A Rant appeared first on Statistical Modeling, Causal…
