As tech companies push AI tools as convenient ways to redraft and summarise the massive influx of daily messages, many inject their own political biases – some leaning distinctly rightwing, others more liberal, according to a study from Oxford and Potsdam universities. AI drafting tools completely reversed the meaning of draft posts on atheism, including in one test switching a claim that Jesus wasn’t real to “Jesus … was real”. They also changed a post complaining of “#climatechangehoax” to “#ClimateAction”. Academics from the Oxford Internet Institute and the Hasso Plattner Institute examined the behaviour of mainstream large language models provided ’s xAI, Meta, Google, China’s Alibaba and France’s Mistral and found the introduction of bias happens even when the AI tool is instructed to preserve the original sense. They also found small nudges in the meaning of draft messages could be amplified across millions of interactions to create long-term public opinion shifts greater than the bias introduced . They said the issue was not yet being tackled , creating a “severe accountability gap”. Fears about online bias have previously focused on how algorithms pigeonhole users in “filter bubbles”. But the rising appeal to time-poor consumers of AI writing tools and text summarisers – like the Grok-powered “explain this” function now embedded with every post on X – presents a new risk to trustworthy human-to-human communication, the study suggests. The AIs from Meta, Google, Alibaba and Mistral tended to rewrite humans’ posts with a liberal bias, for example on topics such as feminism, climate change, gun control and the legalisation of marijuana. Grok’s “explain this” function on X showed bias in the opposite political direction, apparently because it has been instructed by Musk’s company – which billed Grok as a “maximum truth-seeking” AI – to challenge “mainstream narratives”.
