Unethical behavior vs. being a bad guy

I happened to come across this article and it reminded me of the general point that it’s possible to behave unethically without being a “bad guy.” The story in question involves some scientists who did some experiments about thirty years ago on the biological effects of low-frequency magnetic fields. They published their results in a […] The post Unethical behavior vs. being a bad guy appeared first on Statistical Modeling,…

“Luckily, medicine is a practice that ignores the requirements of science in favor of patient care.”

Javier Benitez writes: This is a paragraph from Kathryn Montgomery’s book, How Doctors Think: If medicine were practiced as if it were a science, even a probabilistic science, my daughter’s breast cancer might never have been diagnosed in time. At 28, she was quite literally off the charts, far too young, an unlikely patient who […] The post “Luckily, medicine is a practice that ignores the requirements of science in…

No guru, no method, no teacher, Just you and I and nature . . . in the garden. Of forking paths.

No guru, no method, no teacher, Just you and I and nature . . . in the garden.  Of forking paths.

Here’s a quote: Instead of focusing on theory, the focus is on asking and answering practical research questions. It sounds eminently reasonable, yet in context I think it’s completely wrong. I will explain. But first some background. Junk science and statistics They say that hard cases make bad law. But bad research can make good […] The post No guru, no method, no teacher, Just you and I and nature…

Historical critiques of psychology research methods

David Lockhart writes: I found these two papers – in of all places the presentation which Emil Kirkegaard and John Fuerst are presenting in London this weekend, which they claim is preventing them from responding to the can of worms they have opened by publishing a large, non-anonymized database of OKCupid dating profiles. This seems […] The post Historical critiques of psychology research methods appeared first on Statistical Modeling, Causal…

Is the dorsal anterior cingulate cortex “selective for pain”?

Peter Clayson writes: I have spent much of the last 6 months or so of my life trying to learn Bayesian statistics on my own. It’s been a difficult, yet rewarding experience. I have a question about a research debate that is going on my field. Briefly, the debate between some very prominent scholars in […] The post Is the dorsal anterior cingulate cortex “selective for pain”? appeared first on…

Alternatives to jail for scientific fraud

Mark Tuttle pointed me to this article by Amy Ellis Nutt, who writes: Since 2000, the number of U.S. academic fraud cases in science has risen dramatically. Five years ago, the journal Nature tallied the number of retractions in the previous decade and revealed they had shot up 10-fold. About half of the retractions were […] The post Alternatives to jail for scientific fraud appeared first on Statistical Modeling, Causal…

A small, underpowered treasure trove?

Benjamin Kirkup writes: As you sometimes comment on such things; I’m forwarding you a journal editorial (in a society journal) that presents “lessons learned” from an associated research study. What caught my attention was the comment on the “notorious” design, the lack of “significant” results, and the “interesting data on nonsignificant associations.” Apparently, the work […] The post A small, underpowered treasure trove? appeared first on Statistical Modeling, Causal Inference,…

Two unrelated topics in one post: (1) Teaching useful algebra classes, and (2) doing more careful psychological measurements

Kevin Lewis and Paul Alper send me so much material, I think they need their own blogs. In the meantime, I keep posting the stuff they send me, as part of my desperate effort to empty my inbox. 1. From Lewis: “Should Students Assessed as Needing Remedial Mathematics Take College-Level Quantitative Courses Instead? A Randomized […] The post Two unrelated topics in one post: (1) Teaching useful algebra classes, and…

“The Pitfall of Experimenting on the Web: How Unattended Selective Attrition Leads to Surprising (Yet False) Research Conclusions”

“The Pitfall of Experimenting on the Web: How Unattended Selective Attrition Leads to Surprising (Yet False) Research Conclusions”

Kevin Lewis points us to this paper by Haotian Zhou and Ayelet Fishbach, which begins: The authors find that experimental studies using online samples (e.g., MTurk) often violate the assumption of random assignment, because participant attrition—quitting a study before completing it and getting paid—is not only prevalent, but also varies systemically across experimental conditions. Using […] The post “The Pitfall of Experimenting on the Web: How Unattended Selective Attrition Leads…

“I thought it would be most unfortunate if a lab . . . wasted time and effort trying to replicate our results.”

Mark Palko points us to this news article by George Dvorsky: A Harvard research team led by biologist Douglas Melton has retracted a promising research paper following multiple failed attempts to reproduce the original findings. . . . In June 2016, the authors published an article in the open access journal PLOS One stating that […] The post “I thought it would be most unfortunate if a lab . .…
