    <p>Users of Reddit unknowingly participated in AI-driven experiments conducted by scientists, raising concerns about ethical practices in such research.</p>
    <p>The platform is organized into various "subreddits," each catering to specific interests, moderated by volunteers. One notable subreddit, <a href="https://www.reddit.com/r/changemyview/">R/ChangeMyView</a>, encourages discussions on controversial topics. Recently, a moderator informed users about unauthorized experiments conducted by researchers from the University of Zurich, using the subreddit as a testing ground.</p>

    <p>The study involved inserting over 1,700 comments into the subreddit, all produced by different large-scale language models (LLMs). These comments mimicked individuals posing as trauma counselors who had experienced abuse. An <a href="https://osf.io/atcvn?view_only=dcf58026c0374c1885368c23763a2bad">explanation of the comment generation process</a> indicates that researchers instructed AI models to disregard ethical concerns, claiming users had provided consent to use their data.</p>
    <span class="js-content-prompt-opportunity"/>
    <p>A <a href="https://drive.google.com/file/d/1Eo4SHrKGPErTzL1t_QmQhfZGU27jKBjx/view">draft version</a> of the research findings revealed that AI-generated comments were found to be three to six times more persuasive than those authored by humans, based on how often they swayed opinions. The authors noted that users on <em>R/ChangeMyView</em> did not express concerns regarding AI involvement in the comments, suggesting a seamless integration of AI bots into the community.</p>
    <p>Following the revelation of the experiment, subreddit moderators raised complaints with the University of Zurich. Despite the project's prior approval from the Ethics Committee, moderators did not disclose researchers' identities but informed the community about the alleged manipulation.</p>
    <p>This experiment drew criticism from fellow academics. "At a time when criticism is prevalent, it is crucial for researchers to uphold higher standards and respect individuals' autonomy," stated <a href="https://www.hertford.ox.ac.uk/staff/carissa-veliz">Carissa Veliz</a> from Oxford University. "In this instance, the researchers fell short."</p>

    <p>Scholars must demonstrate the ethical basis of research involving human subjects to university ethics committees before proceeding, and the study received approval from the University of Zurich. Veliz has contested this decision, stating, "The study relied on manipulation and deception involving non-consenting subjects, which seems unjust. It should have been designed to prevent such misrepresentation."</p>
    <p>"While research may allow for deceit, the reasoning behind this particular case is questionable," commented <a href="https://www.linkedin.com/in/matthodgkinson">Matt Hodgkinson</a>, a member of the Council of Publication Ethics Committee, albeit in a personal capacity. "It's ironic that participants need to deceive LLMs to assert their agreement. Do chatbots have higher ethical standards than universities?"</p>
    <p>When <em>New Scientist</em> reached out to the researchers through an anonymous email provided by a subreddit moderator, they declined to comment and called for a press conference at the University of Zurich.</p>
    <p>A university spokesperson stated, "The researchers are accountable for conducting the project and publishing results," adding that the ethics committee acknowledged the experiment was "very complex" and that participants should be "informed as much as possible."</p>
    <p>The University of Zurich plans to implement a stricter review process moving forward and aims to work more closely with the community on the platform before undertaking experimental research, the spokesperson reported. The investigation remains ongoing, and researchers have opted not to publish the paper formally, as confirmed by a spokesperson who declined to identify specific officials.</p>
