A group of researchers in the United States and China have retracted their 2018 paper on hand hygiene, admitting that they can’t account for “data anomalies” in their work.
The article in question, “The decoy effect as a nudge: Boosting hand hygiene with a worse option,” appeared in Psychological Science last May. Led by Meng Li, of the Department of Health and Behavioral Sciences at the University of Colorado Denver, the researchers reported results from experiments designed to increase the use of hand sanitizer in the workplace through the use of a “decoy” bottle:
As we’re fond of repeating, sunlight is the best disinfectant. Which doesn’t jibe with the findings in an eye-catching 2018 paper that found people were less fearful of catching a contagious illness if they were in a dark room or were wearing sunglasses.
Fortunately for us, although not for the researchers, we no longer have to live with the cognitive dissonance. The paper, the journal tells us, will be retracted for flaws in the data — which, thanks to the open sharing of data, quickly came to light.
If you read this space, you probably know the name Brad Bushman. He studies the effects of violent video games on the people who play them. He also has just retracted his third paper, and significantly corrected another.
The retraction notice from Current Opinion in Psychology states the paper showed too much similarity to a 2016 paper in the same journal by Bushman and Arlin James Benjamin, based at the University of Arkansas-Fort Smith. It notes that although Bushman was the guest editor of the issue of the journal:
A highly cited paper has received a major correction as a result of the ongoing battle over attitudes towards gay people, when a prominent — and polarizing — critic showed it could not be replicated.
In December 2017, researchers led by Mark Hatzenbuehler of Columbia University corrected thepaper, originally published in Social Science & Medicine in February 2014, which showed that gay people who live in areas where people were highly prejudiced against them had a significantly shorter life expectancy. The corrigendum came more than a year after a researcher who has testified against same-sex marriage was unable to replicate the original study.
“Structural stigma and all-cause mortality in sexual minority populations,” has been cited 102 times, according to Clarivate Analytics’ Web of Science, and attracted media coverage when it was published, from outlets such as Reuters andU.S. News & World Report.
