Let’s get hysterical

Following up on our discussion of hysteresis in the scientific community, Nick Brown points us to this article this article from 2014, “Excellence by Nonsense: The Competition for Publications in Modern Science,” by Mathias Binswanger, who writes: To ensure the efficient use of scarce funds, the government forces universities and professors, together with their academic […]

How feminism has made me a better scientist

Feminism is not a branch of science. It is not a set of testable propositions about the observable world, nor is it any single research method. From my own perspective, feminism is a political movement associated with successes such as votes for women, setbacks such as the failed Equal Rights Amendment, and continuing struggles in […]

Some thoughts after reading “Bad Blood: Secrets and Lies in a Silicon Valley Startup”

I just read the above-titled John Carreyrou book, and it’s as excellent as everyone says it is. I suppose it’s the mark of any compelling story that it will bring to mind other things you’ve been thinking about, and in this case I saw many connections between the story of Theranos—a company that raised billions […]

Let’s be open about the evidence for the benefits of open science

A reader who wishes to remain anonymous writes: I would be curious to hear your thoughts on is motivated reasoning among open science advocates. In particular, I’ve noticed that papers arguing for open practices have seriously bad/nonexistent causal identification strategies. Examples: Kidwell et al. 2017, Badges to Acknowledge Open Practices: A Simple, Low-Cost, Effective Method […]

Response to Rafa: Why I don’t think ROC [receiver operating characteristic] works as a model for science

Someone pointed me to this post from a few years ago where Rafael Irizarry argues that scientific “pessimists” such as myself are, at least in some fields, “missing a critical point: that in practice, there is an inverse relationship between increasing rates of true discoveries and decreasing rates of false discoveries and that true discoveries […]

The replication crisis and the political process

Jackson Monroe writes: I thought you might be interested in an article [by Dan McLaughlin] in NRO that discusses the replication crisis as part of a broadside against all public health research and social science. It seemed as though the author might be twisting the nature of the replication crisis toward his partisan ends, but […]

Revisiting “Is the scientific paper a fraud?”

Javier Benitez points us to this article from 2014 by Susan Howitt and Anna Wilson, which has subtitle, “The way textbooks and scientific research articles are being used to teach undergraduate students could convey a misleading image of scientific research,” and begins: In 1963, Peter Medawar gave a talk, Is the scientific paper a fraud?, […]

How to think about an accelerating string of research successes?

While reading this post by Seth Frey on famous scientists who couldn’t let go of bad ideas, I followed a link to this post by David Gorski from 2010 entitled, “Luc Montagnier: The Nobel disease strikes again.” The quick story is that Montagnier endorsed some dubious theories. Here’s Gorski: He only won the Nobel Prize […]

Advice on soft skills for academics

Julia Hirschberg sent this along to the natural language processing mailing list at Columbia: here are some slides from last spring’s CRA-W Grad Cohort and previous years that might be of interest. all sorts of topics such as interviewing, building confidence, finding a thesis topic, preparing your thesis proposal, publishing, entrepreneurialism, and a very interesting […]

Journals and refereeing: toward a new equilibrium

As we’ve discussed before (see also here), one of the difficulties of moving from our current system of review of scientific journal articles, to a new model of post-publication review, is that any major change seems likely to break the current “gift economy” system in which thousands of scientists put in millions of hours providing […]

Recently in the sister blog

In the article, “Testing the role of convergence in language acquisition, with implications for creole genesis,” Marlyse Baptista et al. write: The main objective of this paper is to test experimentally the role of convergence in language acquisition (second language acquisition specifically), with implications for creole genesis. . . . Our experiment is unique on […]

“A Headline That Will Make Global-Warming Activists Apoplectic”

I saw this article in the newspaper today, “2017 Was One of the Hottest Years on Record. And That Was Without El Niño,” subtitled, “The world in 2017 saw some of the highest average surface temperatures ever recorded, surprising scientists who had expected sharper retreat from recent record years,” and accompanied by the above graph, […]

“The idea of replication is central not just to scientific practice but also to formal statistics . . . Frequentist statistics relies on the reference set of repeated experiments, and Bayesian statistics relies on the prior distribution which represents the population of effects.”

Rolf Zwaan (who we last encountered here in “From zero to Ted talk in 18 simple steps”), Alexander Etz, Richard Lucas, and M. Brent Donnellan wrote an article, “Making replication mainstream,” which begins: Many philosophers of science and methodologists have argued that the ability to repeat studies and obtain similar results is an essential component […]

“For professional baseball players, faster hand-eye coordination linked to batting performance”

Kevin Lewis sends along this press release reporting what may be the least surprising laboratory finding since the classic “Participants reported being hungrier when they walked into the café (mean = 7.38, SD = 2.20) than when they walked out [mean = 1.53, SD = 2.70, F(1, 75) = 107.68, P < 0.001]."

The “Carl Sagan effect”

Javier Benítez writes: I am not in academia, but I have learned a lot about science from what’s available to the public. But I also didn’t know that public outreach is looked down upon by academia. See the Carl Sagan Effect. Susana Martinez-Conde writes: One scientist, who agreed to participate on the condition of anonymity—an […]

The course of science

Shravan Vasishth sends this along: Yup. Not always, though. Even though the above behavior is rewarded.

Exercise and weight loss: long-term follow-up

This post is by Phil Price, not Andrew. Waaaay back in 2010, I wrote a blog entry entitled “Exercise and Weight Loss.” I had added high-intensity interval training back into my exercise regime, and had lost 12 pounds in about 12 weeks; but around the same time, some highly publicized studies were released that claimed […]

The “Psychological Science Accelerator”: it’s probably a good idea but I’m still skeptical

Asher Meir points us to this post by Christie Aschwanden entitled, “Can Teamwork Solve One Of Psychology’s Biggest Problems?”, which begins: Psychologist Christopher Chartier admits to a case of “physics envy.” That field boasts numerous projects on which international research teams come together to tackle big questions. Just think of CERN’s Large Hadron Collider or […]

When does the quest for beauty lead science astray?

Under the heading, “please blog about this,” Shravan Vasishth writes: This book by a theoretical physicist [Sabine Hossenfelder] is awesome. The book trailer is here. Some quotes from her blog: “theorists in the foundations of physics have been spectacularly unsuccessful with their predictions for more than 30 years now.” “Everyone is happily producing papers in […]

What is the role of qualitative methods in addressing issues of replicability, reproducibility, and rigor?

Kara Weisman writes: I’m a PhD student in psychology, and I attended your talk at the Stanford Graduate School of Business earlier this year. I’m writing to ask you about something I remember you discussing at that talk: The possible role of qualitative methods in addressing issues of replicability, reproducibility, and rigor. In particular, I […]
