Fritz Strack sends along this article from 2012 which has an interesting perspective. Strack’s article begins: But, he continues, things changed in 2011 with the scandals of Diederik Stapel (a career built upon fake data), Daryl Bem (joke science getting published in a real journal), and a seemingly unending series of prominent studies that failed […]

That study about the health risks of red meat: An excellent news report
A couple different people pointed me to this excellent news article by Gina Kolata (with Brad Plumer), who writes: Public health officials for years have urged Americans to limit consumption of red meat and processed meats because of concerns that these foods are linked to heart disease, cancer and other ills. But on Monday, in […]
Here’s a supercool controversy for ya
Raghu Parthasarathy writes: You might like this very good article by Ashley Smart on a recent fight about the statistical mechanics of water, and a feud that was made worse by a lack of sharing code Condensed matter theory! That’s what I worked on, back when I was a physicist. We did an experiment that […]
Dan’s Paper Corner: Can we model scientific discovery and what can we learn from the process?
Jesus taken serious by the many Jesus taken joyous by a few Jazz police are paid by J. Paul Getty Jazzers paid by J. Paul Getty II Leonard Cohen So I’m trying a new thing because like no one is really desperate for another five thousand word essay about whatever happens to be on my […]
Brief summary notes on Statistical Thinking for enabling better review of clinical trials.
This post is not by Andrew. Now it was spurred by Andrew’s recent post on Statistical Thinking enabling good science. The day of that post, I happened to look in my email’s trash and noticed that it went back to 2011. One email way back then had an attachment entitled Learning Priorities of RCT versus […]
“Superior: The Return of Race Science,” by Angela Saini
“People so much wanted the story to be true . . . that they couldn’t look past it to more mundane explanations.” – Angela Saini, Superior. I happened to be reading this book around the same time as I attended the Metascience conference, which was motivated by the realization during the past decade or so […]
I think that science is mostly “Brezhnevs.” It’s rare to see a “Gorbachev” who will abandon a paradigm just because it doesn’t do the job. Also, moving beyond naive falsificationism
Sandro Ambuehl writes: I’ve been following your blog and the discussion of replications and replicability across different fields daily, for years. I’m an experimental economist. The following question arose from a discussion I recently had with Anna Dreber, George Loewenstein, and others. You’ve previously written about the importance of sound theories (and the dangers of […]
Let’s try this again: It is nonsense to say that we don’t know whether a specific weather event was affected by climate change. It’s not just wrong, it’s nonsensical.
This post is by Phil Price, not Andrew. If you write something and a substantial number of well-intentioned readers misses your point, the problem is yours. Too many people misunderstood what I was sayinga few days ago in the post “There is no way to prove that [an extreme weather event] either was, or was […]
Was Thomas Kuhn evil? I don’t really care.
OK, I guess I care a little . . . but when it comes to philosophy, I don’t really care about Kuhn’s personality or even what exactly he said in his books. I use Kuhn in my work, by which I mean that I use an idealized Kuhn, I take the best from his work […]
My talk at the Metascience symposium Fri 6 Sep
The meeting is at Stanford, and here’s my talk: Embracing Variation and Accepting Uncertainty: Implications for Science and Metascience The world would be pretty horrible if your attitude on immigration could be affected by a subliminal smiley face, if elections were swung by shark attacks and college football games, if how you vote depended on […]
“I am a writer for our school newspaper, the BHS Blueprint, and I am writing an article about our school’s new growth mindset initiative.”
Caleb VanArragon writes: I am a student at Blaine High School in Blaine, Minnesota. I am a writer for our school newspaper, the BHS Blueprint, and I am writing an article about our school’s new growth mindset initiative. I was wondering if you would be willing to answer a couple of questions about your study […]
More on the piranha problem, the butterfly effect, unintended consequences, and the push-a-button, take-a-pill model of science
The other day we had some interesting discussion that I’d like to share. I started by contrasting the butterfly effect—the idea that a small, seemingly trivial, intervention at place A can potentially have a large, unpredictable effect at place B—with the “PNAS” or “Psychological Science” view of the world, in which small, seemingly trivial, intervention […]

Researchers respond to a correction by acknowledging it and not trying to dodge its implications”): Coming down from Psych Science Stopping off at PNAS Out all day datagathering And the craic was good Stopped off at the old lab Early in the morning Drove through Harvard taking pictures And […]
“The issue of how to report the statistics is one that we thought about deeply, and I am quite sure we reported them correctly.”
Ricardo Vieira writes: I recently came upon this study from Princeton published in PNAS: Implicit model of other people’s visual attention as an invisible, force-carrying beam projecting from the eyes In which the authors asked people to demonstrate how much you have to tilt an object before it falls. They show that when a human […]
Why does my academic lab keep growing?
Andrew, Breck, and I are struggling with the Stan group funding at Columbia just like most small groups in academia. The short story is that to apply for enough grants to give us a decent chance of making payroll in the following year, we have to apply for so many that our expected amount of […]
Concerned about demand effects in psychology experiments? Incorporate them into the design.
Johannes Haushofer sends along this article with Jonathan de Quidt and Christopher Roth, “Measuring and Bounding Experimenter Demand,” which begins: We propose a technique for assessing robustness to demand effects of findings from experiments and surveys. The core idea is that by deliberately inducing demand in a structured way we can bound its influence. We […]
“Developing Digital Privacy: Children’s Moral Judgments Concerning Mobile GPS Devices”
Recently in the sister blog: New technology poses new moral problems for children to consider. We examined whether children deem object tracking with a mobile GPS device to be a property right. In three experiments, 329 children (4-10 years) and adults were asked whether it is acceptable to track the location of either one’s own […]
Alison Mattek on physics and psychology, philosophy, models, explanations, and formalization
Alison Mattek writes: I saw your recent blog post on falsifiable claims. For the past couple of years I have been developing a theoretical framework that highlights the importance of unfalsifiable claims in science. I try to also make a few unfalsifiable claims regarding psychological variables. Here is Mattek’s paper, “Expanding psychological theory using system […]
“The most mysterious star in the galaxy”
Charles Margossian writes: The reading for tomorrow’s class reminded me of a project I worked on as an undergraduate. It was the planet hunter initiative. The project shows light-curves to participants and asks them to find transit signals (i.e. evidence of a transiting planets). The idea was to rely on human pattern recognition capabilities to […]
Endless citations to already-retracted articles
Ken Cor and Gaurav Sood write: Many claims in a scientific article rest on research done by others. But when the claims are based on flawed research, scientific articles potentially spread misinformation. To shed light on how often scientists base their claims on problematic research, we exploit data on cases where problems with research are […]
