The feather, the bathroom scale, and the kangaroo

Here’s something I wrote in the context of one of those “power = .06″ studies: My criticism of the ovulation-and-voting study is ultimately quantitative. Their effect size is tiny and their measurement error is huge. My best analogy is that they are trying to use a bathroom scale to weigh a feather—and the feather is […]

Diederik Stapel in the news, again

Bikes . . . have “become the most common mode of transportation for criminals.” OK, that’s just ethnic profiling of Dutch people. I think they’re just gonna put the whole country on lockdown.

How do data and experiments fit into a scientific research program?

I was talking with someone today about various “dead on arrival” research programs we’ve been discussing here for the past few years: I’m talking about topics such beauty and sex ratios of children, or ovulation and voting, or ESP—all of which possibly represent real phenomena and could possibly be studied in a productive way, just […]

A silly little error, of the sort that I make every day

Ummmm, running Stan, testing out a new method we have that applies EP-like ideas to perform inference with aggregate data—it’s really cool, I’ll post more on it once we’ve tried everything out and have a paper that’s in better shape—anyway, I’m starting with a normal example, a varying-intercept, varying-slope model where the intercepts have population […]

Outside pissing in

Coral Davenport writes in the New York Times: Mr. Tribe, 73, has been retained to represent Peabody Energy, the nation’s largest coal company, in its legal quest to block an Environmental Protection Agency regulation that would cut carbon dioxide emissions from the nation’s coal-fired power plants . . . Mr. Tribe likened the climate change […]

Round of 8 bracket; Ed Wood (3) vs. Thomas Hobbes; Philip K. Dick (2) vs. Jane Austen

Paul Davidson sends along the updated bracket, along with the comment that the writers seem to be doing very well. True! The 8 remaining contestants include 5 writers (along with one comedian, one philosopher, and one cult figure). Yesterday we had no competition because I was afraid that people would not take it seriously on […]

There are 5 ways to get fired from Caesars: (1) theft, (2) sexual harassment, (3) running an experiment without a control group, (4) keeping a gambling addict away from the casino, and (5) chapter 11 bankruptcy proceedings

We first encountered the famous casino operator in February, 2011, when Michael Schrage was hyping the data-driven philosophy of its CEO, Gary Loveman, in Technology Review. Here’s a typical bit from the article: Schrage: What do you like to tell your academic colleagues about the challenges of real-world experimentation and innovation? Loveman: Honestly, my only […]

Enough with the replication police

Can’t those shameless little bullies just let scientists do their research in peace? If a hypothesis test is statistically significant and a result is published in a real journal, that should be enough for any self-styled skeptic. Can you imagine what might happen if any published result could be questioned—by anybody? You’d have serious psychology […]

Another disgraced primatologist . . . this time featuring “sympathetic dentists”

Shravan Vasishth points us to this news item from Luke Harding, “History of modern man unravels as German scholar is exposed as fraud”: Other details of the professor’s life also appeared to crumble under scrutiny. Before he disappeared from the university’s campus last year, Prof Protsch told his students he had examined Hitler’s and Eva […]

“In general I think these literatures have too much focus on data analysis and not enough on data collection.”

Mike Zyphur pointed me to an article appearing in Psychological Bulletin with a meta-analysis of ovulatory cycle effects: Title: Do Women’s Mate Preferences Change Across the Ovulatory Cycle? A Meta-Analytic Review Authors: Gildersleeve, K; Haselton, MG; Fales, MR Source: PSYCHOLOGICAL BULLETIN , 140 (5):1205-1259; SEP 2014 Abstract: Scientific interest in whether women experience changes across […]
