Sokal: “science is not merely a bag of clever tricks . . . Rather, the natural sciences are nothing more or less than one particular application — albeit an unusually successful one — of a more general rationalist worldview”

Alan Sokal writes: We know perfectly well that our politicians (or at least some of them) lie to us; we take it for granted; we are inured to it. And that may be precisely the problem. Perhaps we have become so inured to political lies — so hard-headedly cynical — that we have lost our […]

I’d like to see a preregistered replication on this one

Under the heading, “Results too good to be true,” Lee Sechrest points me to this discussion by “Neuroskeptic” of a discussion by psychology researcher Greg Francis of a published (and publicized) claim by biologists Brian Dias and Kerry Ressler that “Parental olfactory experience [in mice] influences behavior and neural structure in subsequent generations.” That’s a […]

Soil Scientists Seeking Super Model

I (Bob) spent last weekend at Biosphere 2, collaborating with soil carbon biogeochemists on a “super model.” Model combination and expansion The biogeochemists (three sciences in one!) have developed hundreds of competing models and the goal of the workshop was to kick off some projects on putting some of them together intos wholes that are […]

Replication controversies

I don’t know what ATR is but I’m glad somebody is on the job of prohibiting replication catastrophe: Seriously, though, I’m on a list regarding a reproducibility project, and someone forwarded along this blog by psychology researcher Simone Schnall, whose attitudes we discussed several months ago in the context of some controversies about attempted replications […]

Guys, we need to talk. (Houston, we have a problem).

This post is by Phil Price. I’m posting it on Andrew’s blog without knowing exactly where he stands on this so it’s especially important for readers to note that this post is NOT BY ANDREW! Last week a prominent scientist, representing his entire team of researchers, appeared in widely distributed television interviews wearing a shirt […]

When am I a conservative and when am I a liberal (when it comes to statistics, that is)?

Here I am one day: Let me conclude with a statistical point. Sometimes researchers want to play it safe by using traditional methods — most notoriously, in that recent note by Michael Link, president of the American Association of Public Opinion Research, arguing against non-probability sampling on the (unsupported) grounds that such methods have “little […]

“Science does not advance by guessing”

I agree with Deborah Mayo who agrees with Carlo Rovelli that “Science does not advance by guessing. It advances by new data or by a deep investigation of the content and the apparent contradictions of previous empirically successful theories.” And, speaking as a statistician and statistical educator, I think there’s a big problem with the […]

Confirmationist and falsificationist paradigms of science

Deborah Mayo and I had a recent blog discussion that I think might be of general interest so I’m reproducing some of it here. The general issue is how we think about research hypotheses and statistical evidence. Following Popper etc., I see two basic paradigms: Confirmationist: You gather data and look for evidence in support […]

Recently in the sister blog

Meritocracy won’t happen: the problem’s with the ‘ocracy’ Does the sex of your child affect your political attitudes? More hype about political attitudes and neuroscience Modern polling needs innovation, not traditionalism Who cares about copycat pollsters? The mythical swing voter Mythical swing voter update No, all Americans are not created equal when it comes to […]

“An Experience with a Registered Replication Project”

Anne Pier Salverda writes: I came across this blog entry, “An Experience with a Registered Replication Project,” and thought that you would find this interesting. It’s written by Simone Schnall, a social psychologist who is the first author of an oft-cited Psych Science(!) paper (“Cleanliness reduces the severity of moral judgments”) that a group of […]
