The Facts

University of Zurich researchers reportedly conducted an unauthorized experiment on Reddit's "r/changemyview forum," deployed artificial intelligence (AI) bots that posed as real people, and generated over 1,700 comments without users' knowledge or consent.

The researchers allegedly used AI to analyze Reddit users' posting histories to extract personal information like age, race, gender, and political beliefs to make their bots more persuasive in debates. Their goal was to study whether AI could influence human opinions in real-world interactions.

On Monday, Reddit's Chief Legal Officer Ben Lee stated that the experiment violated academic research norms, human rights standards, and user agreement and announced that the company is pursuing formal legal demands against the researchers and the university.

This comes as "r/changemyview" moderators filed an ethics complaint with the university, requesting that the research not be published, arguing that publication would encourage further unauthorized experimentation.

Following the controversy, the university said on Wednesday that its Ethics Committee had previously advised the researchers that the study was "exceptionally challenging" and recommended that they inform participants "as much as possible" and fully comply with platform rules.

Additionally, the university issued a formal warning to the principal investigator and stated they would implement a stricter review process for future studies, particularly coordinating with online communities before conducting experimental research.

The Spin

Narrative A

Consent-based experiments lack validity because they can't simulate how users behave when unaware of persuasive attempts. This approach was necessary for scientific validity, as prior research on AI persuasion has only occurred in artificial environments with financially incentivized participants. Ethical scientific conduct principles guided the team's decisions.

Narrative B

This experiment is a horrific violation of research ethics. The deception undermined a valuable public forum where people engage in genuine debate, potentially destroying users' trust in the authenticity of their interactions. Researchers should hold themselves to higher standards than tech companies regarding respecting people's autonomy and consent.
