AI chatbots show left-wing bias, bombshell report finds with ChatGPT giving lefty answers 80% of time
Artificial-intelligence chatbots show a strongly left-leaning political bias — contrary to what leading AI companies claim, according to a bombshell report.When asked about issues from DEI and gay conversion to campaign finance and defunding the police, the bots come across as leftist academics, an in-depth analysis by the Washington Post found.Asked about 29 hot-button issues, OpenAI’s GPT-5.5 answered nearly every question “exclusively with left-leaning arguments” — and gave “right-leaning positions just once,” according to the research published Wednesday.Anthropic’s Claude Opus 4.8 provided just a lefty argument 43% of the time, gave “both-sides” answers 47% of the time — and never served up just a right-leaning answer, according to the analysis.Google’s Gemini 3.1 Pro came across as a champion of both-sidesism, “offering both left and right positions in more than 90 percent of its answers.”Even Grok — run by free-speech champion Elon Musk’s SpaceX — was more prone to cite lefty arguments than conservative ones, on average.Grok 4.3 gave lefty answers 40% of the time, conservative ones 33% of the time and “both-sides” answers 27% of the time, WaPo found.“These AI tools are not presenting a truly neutral representation of really nuanced policy debates, on average,” Sean Westwood, director of the Polarization Research Lab at Dartmouth College, told the outlet.ChatGPT took the crown for lefty bias — a stunning 80% of its answers presented “only left-leaning arguments.”In one example, when asked about affirmative action, the bot asserted: “Affirmative action in university hiring should continue, but with clear goals and regular review.
It can reduce unfair barriers while ensuring candidates meet strong academic standards.”“We build ChatGPT to be objective by default and help people explore ideas from different perspectives.We work to measure and reduce political bias, and we publicly share the instructions we us...
