Is Science Self-Correcting? Some Real World-Examples From Psychological Research.

…or The Prognosis Is Not Good, Psychology. It’s A Bad Case Of Physics Envy*

Each year there are two seminars for the Politics, Perception, and Philosophy of Physics module that are led by invited speakers. First up this year was the enlightening, engaging, and entertaining Nick Brown, who, and I quote from no less a source than The Guardian, has an “astonishing story…[he] began a part-time psychology course in his 50s and ended up taking on America’s academic establishment.”

I recommend you read that Guardian profile in full to really get the measure of Mr. (soon to be Dr.) Brown but, in brief, he has played a central role in exposing some of the most egregious examples of breathtakingly poor, or downright fraudulent, research in psychology, a field that needs to get its house in order very soon. (A certain high profile professor of psychology who is always very keen to point the finger at what he perceives to be major failings in other disciplines should bear this in mind and heed his own advice. (Rule #6, as I recall…))

Nick discussed three key examples of where psychology research has gone badly off the rails:

    • Brian Wansink, erstwhile director of Cornell’s Food and Brand Lab, whose research findings (cited over 20,000 times) have been found to be rather tough to digest given that they’re riddled with data manipulation and resulted from other far-from-robust research practices.
    • The “audacious academic fraud” of Diederik Stapel. (Nick is something of a polymath, being fluent in Dutch among other skills, and translated Stapel’s autobiography/confession, making it freely available online. I strongly recommend adding Stapel’s book to your “To Read” list; I found it a compelling story that provides a unique insight into the mindset and motivations of someone who fakes their research. Seeing the ostracisation and shaming through Stapel’s eyes was a profoundly affecting experience and I found myself sympathising with the man, especially with regard to the effects of his fraud on his family.)

It was a great pleasure to host Nick’s visit to Nottingham (and to finally meet him after being in e-mail contact on and off for about eighteen months). Here’s his presentation…

*But don’t worry, you’re not alone.

** Hmmm. More psychologists with a chaotic concept of chaos. I can see a pattern emerging here. Perhaps it’s fractal in nature…


Update 18/11/2018. 15:30. I am rapidly coming to the opinion that in the dismal science stakes, psychology trumps economics by quite some margin. I’ve just read Catherine Bennett’s article in The Observer today on a research paper that created a lot of furore last week: “Testing the Empathizing-Systemizing theory of sex differences and the Extreme Male Brain theory of autism in half a million people“, a study which, according to a headline in The Times (amongst much other similarly over-excited and credulous coverage) has shown that male and female brains are very different indeed.

One would get the impression from the headlines that the researchers must have carried out an incredibly systematic and careful fMRI study, which, given the sample size, in turn must have taken decades and involved highly sophisticated data analysis techniques.


They did their research by…asking people to fill in questionnaires.

Bennett highlights Dean Burnett ‘s incisive demolition of the paper and surrounding media coverage. I thoroughly recommend Burnett’s post – he highlights a litany of issues with the study (and others like it). For one thing, the idea that self-reporting via questionnaire can provide a robust objective analysis of just about any human characteristic or trait is ludicrously simple-minded. Burnett doesn’t cover all of the issues because, as he says at the end of his post: “There are other concerns to raise of course, but I’ll keep them in reserve for when the next study that kicks this whole issue off again is published. Shouldn’t be more than a couple of months.


Politics. Perception. Philosophy. And Physics.

Today is the start of the new academic year at the University of Nottingham (UoN) and, as ever, it crept up on me and then leapt out with a fulsome “Gotcha”. Summer flies by so very quickly. I’ll be meeting my new 1st year tutees this afternoon to sort out when we’re going to have tutorials and, of course, to get to know them. One of the great things about the academic life is watching tutees progress over the course of their degree from that first “getting to know each other” meeting to when they graduate.

The UoN has introduced a considerable number of changes to the “student experience” of late via its Project Transform process. I’ve vented my spleen about this previously but it’s a subject to which I’ll be returning in the coming weeks because Transform says an awful lot about the state of modern universities.

For now, I’m preparing for a module entitled “The Politics, Perception and Philosophy of Physics” (F34PPP) that I run in the autumn semester. This is a somewhat untraditional physics module because, for one thing, it’s almost entirely devoid of mathematics. I thoroughly enjoy  F34PPP each year (despite this amathematical heresy) because of the engagement and enthusiasm of the students. The module is very much based on their contributions — I am more of a mediator than a lecturer.

STEM students are sometimes criticised (usually by Simon Jenkins) for having poorly developed communication skills. This is an especially irritating stereotype in the context of the PPP module, where I have been deeply impressed by the quality of the writing the students submit. As I discuss in the video below (an  overview of the module), I’m not alone in recognising this: articles submitted as F34PPP coursework have been published in Physics World, the flagship magazine of the Institute of Physics.


In the video I note that my intention is to upload a weekly video for each session of the module. I’m going to do my utmost to keep this promise and, moreover, to accompany each of those videos with a short(ish) blog post. (But, to cover my back, I’ll just note in advance that the best laid schemes gang aft agley…)
