Ticket to Baaaaarf

A link from the comments here took me to the wonderfully named Barfblog and a report by Don Schaffner on some reporting. First, the background: A university in England issued a press release saying that “Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is […]

Stan Model of the Week: Hierarchical Modeling of Supernovas

The Stan Model of the Week showcases research using Stan to push the limits of applied statistics.  If you have a model that you would like to submit for a future post then send us an email. Our inaugural post comes from Nathan Sanders, a graduate student finishing up his thesis on astrophysics at Harvard. […]

“More research from the lunatic fringe”

A linguist send me an email with the above title and a link to a paper, “The Effect of Language on Economic Behavior: Evidence from Savings Rates, Health Behaviors, and Retirement Assets,” by M. Keith Chen, which begins: Languages differ widely in the ways they encode time. I test the hypothesis that languages that grammatically […]

Empirical implications of Empirical Implications of Theoretical Models

Robert Bloomfield writes: Most of the people in my field (accounting, which is basically applied economics and finance, leavened with psychology and organizational behavior) use ‘positive research methods’, which are typically described as coming to the data with a predefined theory, and using hypothesis testing to accept or reject the theory’s predictions. But a substantial […]

Ma conférence demain (mardi) à l’École Polytechnique

À 11h15 au Centre de Mathématiques Appliquées: Peut-on utiliser les méthodes bayésiennes pour résoudre la crise des résultats de la recherche statistiquement significatifs que ne tiennent pas? It’s the usual story: the audience will be technical but with a varying mix of interests, and so what they most wanted to hear was something general and […]

What if I were to stop publishing in journals?

In our recent discussion of modes of publication, Joseph Wilson wrote, “The single best reform science can make right now is to decouple publication from career advancement, thereby reducing the number of publications by an order of magnitude and then move to an entirely disjointed, informal, online free-for-all communication system for research results.” My first […]

Preregistration: what’s in it for you?

Chris Chambers pointed me to a blog by someone called Neuroskeptic who suggested that I preregister my political science studies: So when Andrew Gelman (let’s say) is going to start using a new approach, he goes on Twitter, or on his blog, and posts a bare-bones summary of what he’s going to do. Then he […]

Reviewing the peer review process?

I received the following email:

Disagreeing to disagree

I was going to post yet one more discussion of our discussion of the discussion of the discussion of some paper that I don’t really care about, but then I was like, aaaahh, what’s the point? So instead here’s a pointer to the first paper I ever published. It’s the very last one on this […]

How much time (if any) should we spend criticizing research that’s fraudulent, crappy, or just plain pointless?

I had a brief email exchange with Jeff Leek regarding our recent discussions of replication, criticism, and the self-correcting process of science. Jeff writes: (1) I can see the problem with serious, evidence-based criticisms not being published in the same journal (and linked to) studies that are shown to be incorrect. I have been mostly […]
