The authors informed the journal that the merge of lab results and other survey data used in the paper resulted in an error regarding the identification codes. Results of the analyses were based on the data set in which this error occurred. Further analyses established the results reported in this manuscript and interpretation of the data are not correct.
Original conclusion: Lower levels of CSF IL-6 were associated with current depression and with future depression […].
Revised conclusion: Higher levels of CSF IL-6 and IL-8 were associated with current depression […].
A business journal has retracted a 2016 paper about how social media can encourage young consumers to become devoted to particular brands, after discovering flaws in the data and findings.
Reasons for retraction:
The journal Heart has retracted a 2012 meta-analysis after learning that two of the six studies included in the review contained duplicated data. Those studies, it so happens, were conducted by one of the co-authors.
The Committee considered that without sight of the raw data on which the two papers containing the duplicate data were based, their reliability could not be substantiated. Following inquiries, it turns out that the raw data are no longer available having been lost as a result of computer failure.
In 2022 the paper “Signing at the beginning makes ethics salient and decreases dishonest self-reports in comparison to signing at the end,” by Lisa L. Shu, Nina Mazar, Francesca Gino, Dan Ariely, and Max H. Bazerman from 2012 was retracted due to the discovery of issues of data fabrication with one of the reported studies (see here).
More recently additional evidence has been found of data fabrication within a different study by a different author.
Convince researchers to adopt a reproducible research workflow.
Train new researchers who don’t have any other workflow.
We need an environment where:
data, analysis, and results are tightly connected, or better yet, inseparable,
reproducibility is built in,
documentation is human readable and syntax is minimal.
“Let us change our traditional attitude to the construction of programs: Instead of imagining that our main task is to instruct a computer what to do, let us concentrate rather on explaining to human beings what we want a computer to do.”
“The practitioner of literate programming […] strives for a program that is comprehensible because its concepts have been introduced in an order that is best for human understanding, using a mixture of formal and informal methods that reinforce each other.”
These ideas have been around for years!
Tools for putting them to practice have also been around.
They have never been as accessible as the current tools.
Scriptability
R / Python
Literate Programming
RMarkdown / Jupyter / Quarto
Version Control
Git / GitHub
Could these tools have prevented some of the aforementioned retractions?
