Data “were destroyed due to privacy/confidentiality requirements,” says co-author of retracted gay canvassing study

science coverAs promised, Michael LaCour, the co-author of the now-retracted Science paper on gay canvassing, has posted a detailed response to the allegations against him.

In the 23-page document — available here — LaCour claims to

introduce evidence uncovering discrepancies between the timeline of events presented in Broockman et al. (2015) and the actual timeline of events and disclosure.

He also says that the graduate students who critiqued his work failed to follow the correct sampling procedure and chose an incorrect variable in what LaCour calls “a curious and possibly intentional ‘error.'” He writes: Continue reading Data “were destroyed due to privacy/confidentiality requirements,” says co-author of retracted gay canvassing study

Science retracts troubled gay canvassing study against LaCour’s objections

science coverFollowing revelations of data issues and other problems (which crashed our server last week), Science is retracting a paper claiming that short conversations could change people’s minds on same-sex marriage.

The co-author who admitted to faking the data “does not agree” to the retraction, according to Science. Here’s more from the note: Continue reading Science retracts troubled gay canvassing study against LaCour’s objections

Author retracts study of changing minds on same-sex marriage after colleague admits data were faked

science coverIn what can only be described as a remarkable and swift series of events, one of the authors of a much-ballyhooed Science paper claiming that short conversations could change people’s minds on same-sex marriage is retracting it following revelations that the data were faked by his co-author.

[3:45 p.m. Eastern, 5/28/15: Please see an update on this story; the study has been retracted.]

Donald Green, of Columbia, and Michael LaCour, a graduate student at UCLA, published the paper, “When contact changes minds: An experiment on transmission of support for gay equality,” in December 2014. The study received widespread media attention, including from This American Life, The New York Times, The Wall Street Journal, The Washington Post,  The Los Angeles Times, Science Friday, Vox, and HuffingtonPost, as LaCour’s site notes.

David Broockman and Joshua Kalla, graduate students at University of California, Berkeley, were two of the people impressed with the work, so they planned an extension of it, as they explain in a timeline posted online yesterday: Continue reading Author retracts study of changing minds on same-sex marriage after colleague admits data were faked

Science chemistry paper earns retraction after expression of concern, marking second for UT group

scienceThe authors of a 2011 Science paper that proposed a new way to direct chemical bonds have withdrawn the paper after concerns about the data prompted an investigation and Editorial Expression of Concern last year from the journal. The retraction is the second for the group, which has also had seven other expressions of concern.

After a reader emailed the editors to raise suspicions about the data, corresponding author Christopher W. Bielawski, then based at the University of Texas at Austin, led an investigation of all the figures. It found substantial problems: “In over 50% of the figure parts, the authors deemed the data unreliable due to uncertainty regarding the origin of data or the manner in which the data were processed,” according to the retraction notice.

UT Austin concluded that there had been misconduct, but did not elaborate.

After 25 years, AIDS fraud comes back swinging

Screen Shot 2015-01-30 at 5.20.32 PMHenk Buck, a Dutch chemist who once claimed he could cure AIDS, is back, publishing a long explanation of why he was right all along in a journal by what Jeffrey Beall calls a possible predatory publisher.

Buck spent a few months in 1990 as a hero. In April of that year, he and his team published a paper in Science that claimed they could prevent HIV from infecting human cells. Buck went on a press blitz, appearing on TV and the radio claiming that there would be a treatment for AIDS “in a few years,” according to an 1991 comment published in Science. 

Like many things that sound too good to be true, the AIDS cure was a fraud. Continue reading After 25 years, AIDS fraud comes back swinging

Faking data earns stem cell researcher a ban on federal funding

Screen shot 2014-12-09 at 12.01.19 PMThe Office of Research Integrity (ORI) has sanctioned Kaushik Deb, a former post-doc at the University of Missouri-Columbia, who “engaged in misconduct in science by intentionally, knowingly, and recklessly” fabricating data in papers in both Science and Nature (which ultimately rejected his manuscript).

Deb was big news in 2007, when Science retracted his paper. Articles about the case appeared in many outlets, including The Scientist and USA Today. At the time, Missouri’s research integrity officer, Rob Hall, told the Columbia Tribune that: Continue reading Faking data earns stem cell researcher a ban on federal funding
