Fighting AI Slop in Science Papers
The preprint server arXiv is implementing a submission cap of two papers per month to combat a surge in low-quality, AI-generated research. This move follows a massive increase in submissions that has strained the platform's moderation resources.
Why it matters
The rise of AI-generated 'slop' in academic publishing poses a significant threat to the integrity and discoverability of scientific research.
AI does everything at scale, from DOS-attack-level web scraping to producing, or enabling, such vast volumes of scientific research submissions that the result is becoming both a logistical crisis and a crisis of quality , as the signal-to-noise ratio continues to become unnavigable.
Last week, preprint server arXiv announced that it will be instituting a new rate-limiting policy for submitters, who will now be capped at two submissions per month. The measure has been taken, the announcement suggests, in the face of a vertiginous rise in submission rates over a short time-period:
