“Positivity ratio” research now subject to an expression of concern

with 9 comments

An expression of concern has been issued for the second of three papers on the idea that, if you have three positive emotions for every negative one, you will be more successful in life.

Psychologist Barbara Fredrickson, of the University of North Carolina, Chapel Hill, has spent the last decade building a brand around this ratio, initially described by a mathematical equation based on fluid dynamics by mathematician Marcial Losada. You can read our coverage of the debunking of that equation, presented in a 1999 paper that has been cited nearly 1,700 times, here.

Nick Brown, co-author with Alan Sokal on the paper that discredited the Losada equation, has written a blog post on the current state of affairs. He also got in touch with us regarding the expression of concern for a 2004 article in American Behavioral Scientist that he had also questioned, “The Role of Positivity and Connectivity in the Performance of Business Teams: A Nonlinear Dynamic Model”: Read the rest of this entry »

Förster on defense again, this time weighing in on timeline controversy

with 72 comments

forster-j-aScience reported last week that Jens Förster, the former University of Amsterdam social psychologist embroiled in data fabrication controversy, may have stumbled in his defense by muddling the timeline of his disputed studies in public statements.

According to a piece by Frank van Kolfschooten (which is behind a paywall, and to which we linked in Saturday’s Weekend Reads):

The real challenge to Förster’s timeline may lie in e-mails between him and Pieter Verhoeven, his research assistant at UvA from September 2008 to June 2009, who made the correspondence available to Förster’s accuser. In it, the two discuss how to conduct what are evidently the same experiments Förster’s blog declares were completed much earlier in Bremen. For instance, among the stimuli used are three unintelligible audio recordings, which the 2011 paper says were described to the subjects as “Moldavian” poems. In an 18 May 2009 e-mail, Verhoeven comes up with the idea to describe the poem that way, rather than as Malaysian, because the reader of the poem has a German accent.

But in a yet another lengthy open letter to colleagues and friends, Förster insists that he conducted the studies in Germany before coming to the University of Amsterdam. And he hints darkly at the end that those seeking to cast doubt on his research may be doing so for personal gain: Read the rest of this entry »

“Misrepresentation,” “reckless disregard for basic scientific standards”: Hauser report reveals details of misconduct

with 14 comments

Harvard-logo_7Courtesy of a Freedom of Information Act request, The Boston Globe has a very good piece detailing what investigators found had actually happened in the Marc Hauser lab before the former Harvard psychology researcher resigned in 2011 and was found guilty of misconduct by the Office of Research Integrity (ORI) in 2012.

The Globe requested the 2010 report Harvard sent the ORI. Here’s a summary:

The 85-page report details instances in which Hauser changed data so that it would show a desired effect. It shows that he more than once rebuffed or downplayed questions and concerns from people in his laboratory about how a result was obtained. The report also describes “a disturbing pattern of misrepresentation of results and shading of truth” and a “reckless disregard for basic scientific standards.”

The Globe quotes key passages from the report: Read the rest of this entry »

smeestersDirk Smeesters, the former Erasmus University psychology researcher found to have committed misconduct, is up to half a dozen retractions.

Both notices, in the Journal of Consumer Research, where Smeesters has already had one retraction, are paywalled. Here’s one, for a paper cited seven times, according to Thomson Scientific’s Web of Knowledge: Read the rest of this entry »

“I never manipulated data”: Förster defends actions in open letter

with 132 comments

Jens Förster

Jens Förster, the Dutch social psychologist accused of misconduct, has posted an open letter on his lab’s website in which he denies wrongdoing.

The letter, in English and dated May 11, offers a detailed rebuttal to the investigation’s conclusions. It also offers a rationale for Förster’s decision not to post his data on the Internet. And it’s followed by a briefer letter from Nira Liberman, who identifies herself as a collaborator of Förster’s.

We present the letter in full below:

Jens Förster

Last week we wrote about the 2012 complaint that triggered the investigation into Jens Förster, the social psychologist at the University of Amsterdam whose work has come under scrutiny for possible fraud.

Now we have the findings of the official investigation by Landelijk Orgaan Wetenschappelijke Integriteit (the Dutch National Board for Scientific Integrity, often referred to as LOWI) — which clearly indicates that the institution believes Förster made up results.

Here are some of the highlights from the document, which we’ve had translated by a Dutch speaker:
