The Hans Eysenck affair: Time to correct the scientific record

Correction of the Scientific Production: Publisher Performance Evaluation Using a Dataset of 4844 PubMed Retractions

Background. Retraction of problematic scientific articles after publication is one of the mechanisms for correcting the literature available to publishers. The market volume and the business model justify publishers’ ethical involvement in the post-publication quality control (PPQC) of human-health-related articles. The limited information about this subject led us to analyze PubMed-retracted articles and the main retraction reasons grouped by publisher. We propose a score to appraise publisher’s PPQC results. The dataset used for this article consists of 4844 PubMed-retracted papers published between 1.01.2009 and 31.12.2020. Methods. An SDTP score was constructed from the dataset. The calculation formula includes several parameters: speed (article exposure time (ET)), detection rate (percentage of articles whose retraction is initiated by the editor/publisher/institution without the authors’ participation), transparency (percentage of retracted articles available online and the clarity of the retraction notes), and precision (mention of authors’ responsibility and percentage of retractions for reasons other than editorial errors). Results. The 4844 retracted articles were published in 1767 journals by 366 publishers, the average number of retracted articles/journal being 2.74. Forty-five publishers have more than 10 retracted articles, holding 88% of all papers and 79% of journals. Combining our data with data from another study shows that less than 7% of PubMed dataset journals retracted at least one article. Only 10.5% of the retraction notes included the individual responsibility of the authors. Nine of the top 11 publishers had the largest number of retracted articles in 2020. Retraction-reason analysis shows considerable differences between publishers concerning the articles’ ET: median values between 9 and 43 months (mistakes), 9 and 73 months (images), and 10 and 42 months (plagiarism and overlap). The SDTP score shows, from 2018 to 2020, an improvement in PPQC of four publishers in the top 11 and a decrease in the gap between 1st and 11th place. The group of the other 355 publishers also has a positive evolution of the SDTP score. Conclusions. Publishers have to get involved actively and measurably in the post-publication evaluation of scientific products. The introduction of reporting standards for retraction notes and replicable indicators for quantifying publishing QC can help increase the overall quality of scientific literature.

Research misconduct complaints and institutional logics: The case of Hans Eysenck and the British Psychological Society

A formal complaint was lodged with the British Psychological Society in 1995 that alleged serious scientific misconduct by Hans J Eysenck. The complaint referred to research into the links between personality traits and the causes, prevention and treatment of cancer and heart disease. Using a framework of institutional logics, we criticise the Society's decision not to hear this complaint at a full disciplinary hearing. We urge the BPS to investigate this complaint afresh. We also support calls for the establishment of an independent National Research Integrity Ombudsperson to deal more effectively with allegations of research misconduct.

The development of a brief measure of health personality

The purpose of this research was to develop a brief assessment of health personality, defined as a set of individual dispositions that are directly related to health. In Study 1, an initial pool of items was developed with 615 older adults, 65 years of age and older. The scale was reduced to a 15-item version for use in applied health care settings. Results indicated that the 'Health Personality Assessment scale' has good internal consistency, and the five-factors correlated significantly with self-reported measures of physical health and well-being. In Study 2, the scale was cross-validated with 254 older adults from the Health Literacy and Cognitive Function among Older Adults Study. The scale was refined and a third study consisted of 3,907 older adults. Reliability and validity of the scale were confirmed. Future research should evaluate the usefulness of this scale in applied healthcare settings.

King's College London's enquiry into Hans J Eysenck's 'Unsafe' publications must be properly completed

This journal recently drew attention to an extensive body of highly questionable research published by Hans J. Eysenck in collaboration with Ronald Grossarth-Maticek. The subsequent enquiry by King's College London concluded that 26 publications were unsafe and warranted retraction. However, the enquiry reviewed only a subset of the 61 questionable publications initially submitted to them, only those Eysenck co-authored with Grossarth-Maticek. The enquiry excluded publications where Eysenck was the sole author. The King's College London enquiry must be properly completed. They have a pressing responsibility to re-convene and broaden their review to include all Eysenck's publications based on the same body of research - including an additional 27 publications recently uncovered. The unsatisfactory nature of the KCL review process makes the case for a National Research Integrity Ombudsperson even stronger.
