The Retraction of Max Planck's 1940s Papers: Algorithmic Error and Historical Record

Algorithmic Errors Led to the Retraction of Max Planck's Historical Papers

Two philosophical papers written by Nobel laureate Max Planck in the 1940s were retracted by the journal Naturwissenschaften (now The Science of Nature) not due to scientific misconduct, but because of algorithmic flags regarding copyright and duplicate publication. The retractions resulted in the removal of the papers from the digital archive, leaving only blank pages and empty PDFs, which historians argue distorts the historical record of science.

The Cause: Copyright Flags and "Duplicate Publication"

Historians Yves Gingras and Mahdi Khelfaoui discovered the retractions while reviewing lists of Nobel Prize winners with retracted work. Their investigation revealed that the retractions were based on "article violation" related to copyright rather than scientific integrity.

Two specific scenarios likely triggered the algorithmic retractions:

• Duplicate Publication: The 1942 paper "Meaning and Limits of Exact Science" was based on a 1941 lecture and appeared in multiple formats, including a booklet and an anthology. Modern algorithms often flag such repetitions as "self-plagiarism" or duplicate publication.
• Cataloguing Ambiguity: The 1940 paper "Natural Science and the Real External World" shared a title with a critique written by another scientist, Aloys Muller, in the same journal. This identical titling likely confused automated tools designed to detect duplication.

Conflict Between Modern Standards and Historical Norms

The retraction of these papers underscores a fundamental disconnect between contemporary academic publishing and the practices of the early 20th century.

Historical Dissemination vs. Modern Copyright

In the 1940s, the priority for scientists was the widest possible dissemination of knowledge across fragmented geographical and linguistic boundaries. It was common practice to publish the same core ideas across lectures, conference proceedings, and journals. In contrast, today's scientific landscape is dominated by commercial publishing groups that prioritize copyright protection and strict rules against duplicate publication, as publications now directly impact hiring, promotion, and funding.

The Role of Automation in Archiving

Evidence suggests the retractions occurred around April 2005 during the industry-wide transition to electronic publishing. Suzanne Scarlata, editor-in-chief of The Science of Nature, stated she was unaware of the retractions until they were brought to her attention, suggesting the process was handled by an automated algorithm without human editorial oversight.

Institutional Response and Impact

Despite the evidence that the retractions were erroneous and that the papers are now in the public domain, the publisher, Springer Nature, has remained largely unresponsive.

• Lack of Transparency: Springer Nature declined to comment on the specific retractions, citing confidentiality policies that restrict information sharing to the original authors—an impossibility given that Max Planck died in 1947.
• Editorial Suppression: The publisher reportedly blocked an editorial that Scarlata intended to publish to address and rectify the mistake.

Historians emphasize that removing these texts is "intellectually not acceptable" as it erases legitimate scientific discourse from the official digital record, even if the papers remain accessible via third-party sources like the Internet Archive.
