How can you evaluate a research paper?

Shea Levy writes: You ended a post from last month [i.e., Feb.] with the injunction to not take the fact of a paper’s publication or citation status as meaning anything, and instead that we should “read each paper on its own.” Unfortunately, while I can usually follow e.g. the criticisms of a paper you might […] The post How can you evaluate a research paper? appeared first on Statistical Modeling,…

“A bug in fMRI software could invalidate 15 years of brain research”

About 50 people pointed me to this press release or the underlying PPNAS research article, “Cluster failure: Why fMRI inferences for spatial extent have inflated false-positive rates,” by Anders Eklund, Thomas Nichols, and Hans Knutsson, who write: Functional MRI (fMRI) is 25 years old, yet surprisingly its most common statistical methods have not been validated […] The post “A bug in fMRI software could invalidate 15 years of brain research”…

Happiness formulas

Jazi Zilber writes: Have you heard of “the happiness formula”? Lyubomirsky at al. 2005. Happiness = 0.5 genetic, 0.1 circumstances, 0.4 “intentional activity” They took the 0.4 unexplained variance and argued it is “intentional activity” Cited hundreds of times by everybody. The absurd is, to you even explaining it is unneeded. For others, I do […] The post Happiness formulas appeared first on Statistical Modeling, Causal Inference, and Social Science.

How not to analyze noisy data:  A case study

I was reading Jenny Davidson’s blog and came upon this note on an autobiography of the eccentric (but aren’t we all?) biologist Robert Trivers. This motivated me, not to read Trivers’s book, but to do some googling which led me to this paper from Plos-One, “Revisiting a sample of U.S. billionaires: How sample selection and […] The post How not to analyze noisy data: A case study appeared first on…

The Psychological Science stereotype paradox

Lee Jussim, Jarret Crawford, and Rachel Rubinstein just published a paper in Psychological Science that begins, Are stereotypes accurate or inaccurate? We summarize evidence that stereotype accuracy is one of the largest and most replicable findings in social psychology. We address controversies in this literature, including the long-standing and continuing but unjustified emphasis on stereotype […] The post The Psychological Science stereotype paradox appeared first on Statistical Modeling, Causal Inference,…

The never-back-down syndrome and the fundamental attribution error

David Allison told me about a frustrating episode in which he published a discussion where he pointed out problems with a published paper, and the authors replied with . . . not even a grudging response, they didn’t give an inch, really ungracious behavior. No “Thank you for finding our errors”; instead they wrote: We […] The post The never-back-down syndrome and the fundamental attribution error appeared first on Statistical…

I refuse to blog about this one

Shravan points me to this article, Twitter Language Use Reflects Psychological Differences between Democrats and Republicans, which begins with the following self-parody of an abstract: Previous research has shown that political leanings correlate with various psychological factors. While surveys and experiments provide a rich source of information for political psychology, data from social networks can […] The post I refuse to blog about this one appeared first on Statistical Modeling,…

The new quantitative journalism

The first of the breed was Bill James. But now we have a bunch: Felix Salmon, Nate Silver, Amanda Cox, Carl Bialik, . . . . I put them in a different category than traditional science journalists such as Malcolm Gladwell, Gina Kolata, Stephen Dubner who are invested in the “scientist as hero” story, or […] The post The new quantitative journalism appeared first on Statistical Modeling, Causal Inference, and…

“Brief, decontextualized instances of colaughter”

Bill Jefferys points me to this news article and writes: Looks at first glance like another NPR example of poor statistics, but who knows? I took a look and here were my thoughts, in order of occurrence: NPR . . . PPNAS . . . Also this: “the results were consistent across all the societies […] The post “Brief, decontextualized instances of colaughter” appeared first on Statistical Modeling, Causal Inference,…
