Swiss university secretly ran AI experiment to manipulate minds
A major Swiss university has come under fire for running a secret experiment on users of social media platform Reddit to test how artificial intelligence (AI) could be used to influence their opinions. The platform has said it is considering legal action.
According to media reports, a group of researchers at the University of Zurich in recent months conducted an unauthorized study on r/ChangeMyView, one of Reddit's largest debate communities. The experiment involved AI chatbots posing as regular users and engaging in discussions on controversial issues.
The bots, whose accounts have since been banned, posted more than 1,700 comments across the subreddit. They adopted fake identities such as a male rape victim downplaying the trauma of his assault, a Black man opposing the Black Lives Matter movement, and a domestic trauma counselor claiming the most vulnerable women were those 'sheltered by overprotective parents.'
Another bot was used to scan user profiles and deliver personalized arguments in response.
The researchers disclosed the experiment to subreddit moderators several months after it had taken place, calling it 'a disclosure step in the study.'
In a statement posted last week, Reddit's moderator team has said the platform prohibits the use of undisclosed AI-generated content or bots. Reddit's chief legal officer, Ben Lee, said neither the company nor the r/ChangeMyView moderators had prior knowledge of what he called an 'improper and highly unethical experiment.' He added that Reddit was preparing formal legal demands to send to the University of Zurich and the researchers involved.
The researchers said the study had been guided by principles of 'ethical' research and transparency. The university ethics committee had argued that the research had caused little harm. Still, users on the subreddit reacted with shock and anger over being unknowingly experimented on.
The journal Science cited an emailed university statement as saying the researchers have decided not to publish the results. The university said it would investigate the incident.
The use of AI bots – fake accounts designed to mimic real users – has grown steadily across social media platforms in recent years. Experts say they are increasingly used to shape public opinion, particularly around elections.
Western governments, primarily the US and the UK, have long accused Russia of operating large-scale 'bot farms' to interfere in their election processes – accusations Moscow has repeatedly denied. However, some Western actors have come under scrutiny themselves for using bots in disinformation campaigns, while publicly warning about foreign interference.

Chinese education is superior to Western
Telegram co-founder and CEO Pavel Durov has attributed China's rapid advancements in artificial intelligence (AI) to its highly competitive education system, emphasizing the nation's consistent excellence in mathematics and programming. In a statement on Wednesday, Durov noted that China's education system fosters 'fierce competition' among students, a principle reminiscent of the 'highly efficient' Soviet model. He contrasted this with Western educational approaches, where competition is often minimized to avoid hurting students' feelings. 'Victory and defeat are two sides of the same coin. Eliminate the losers — and you eliminate the winners,' Durov wrote in a post celebrating the Chinese New Year. Durov emphasized that while telling all students they are champions, regardless of performance, may seem kind, reality will quickly shatter this illusion after graduation. READ MORE: OpenAI founder admits China's DeepSeek is 'impressive' 'Reality, unlike well-meaning school policies, does have public grades and rankings — whether in sports, business, science, or technology,' he wrote on Wednesday, warning that removing transparency in student performance can make school feel meaningless for ambitious teenagers. 'AI benchmarks that demonstrate DeepSeek's superiority are one of such public rankings. And more are coming,' he cautioned. 'China's progress in algorithmic efficiency hasn't come out of nowhere,' Durov explained, noting that Chinese students have 'long outperformed others in math and programming at international Olympiads.' READ MORE: Putin calls for AI alliance with China China leads the US in cumulative medal counts in the International Mathematical Olympiad (IMO), with 185 gold medals to 151, as well as 102 to 68 in the International Olympiad in Informatics (IOI). While the US managed to beat China by a mere two points in the 2024 IMO, ending its decade-long reign, some critics attributed the victory to the 'disproportionate' Asian representation on the American team. Durov's comments come in the wake of the success of Chinese AI startup DeepSeek, which has developed an open-source reasoning model without access to cutting-edge US chips and at a fraction of the cost. He cautioned that unless the US education system undergoes significant reforms to encourage competition and recognize excellence, China's growing dominance in technology appears inevitable.

Iran sends ‘heaviest payload ever' into space
Iran has launched its heaviest payload ever into space using its home-grown Simorgh carrier rocket, state television reported on Friday. The launch included an advanced module for transferring satellites into higher orbits, the Saman-1, as well as the Fakhr-1 communications satellite developed by Iran's military. Both were 'successfully placed in an elliptical orbit with a high point of 410 kilometers,' the broadcast said, according to Reuters. It added that the weight sent into space, just over 660 lbs, marked a 'national record for the heaviest payload launched into orbit. The launch comes as tensions between Iran and the West have been growing over conflicts in the Middle East, and over Tehran's nuclear program, which Western nations, including the US, France, Germany and the UK have branded a 'threat' to international security. The West has also accused Tehran of transferring ballistic missiles to Russia amid its conflict with Ukraine. The Simorgh rocket was launched from the Imam Khomeini Spaceport in the rural Semnan province, some 220 kilometers (about 140 miles) east of Tehran, where its civilian space program is located. Iran used the Simorgh rocket for the first time in January, sending three satellites into space. A US intelligence report in July suggested that Tehran's space launch program would probably 'shorten the timeline' for it to produce an intercontinental ballistic missile, since similar technologies are used for both systems. UN Security Council resolutions, which expired in October 2023, urged Iran to halt activities involving ballistic missiles that are capable of carrying nuclear warheads. Tehran has always maintained that both its nuclear and space programs are entirely peaceful. Under the 2015 Iran nuclear deal, the country agreed to curb its nuclear program in exchange for partial sanctions relief. However, when then-US President Donald Trump unilaterally withdrew from the deal in 2018, diplomatic efforts to revive it failed and Tehran stepped up its uranium enrichment to 60%. Last year, media reports claimed that the International Atomic Energy Agency (IAEA) was investigating Iran for enriching Uranium to 84%, which is 'just 6% below what's needed for a weapon.' However, Tehran dismissed this at the time as 'slander and a distortion of the facts.' In November, French intelligence claimed Tehran could acquire a nuclear weapon within months, which it called a 'most critical threat.' A senior aide to Iranian Supreme Leader Ayatollah Ali Khamenei confirmed last month, however, that Tehran possesses 'the technical capabilities necessary to produce nuclear weapons.' He said while there is no plan to create the weapons, Iran reserves the right to 'reconsider' if its survival is under threat.
