Are ChatGPT and other AI chatbots politically biased? We tested them.

President Donald Trump and other conservatives have accused artificial intelligence chatbots of being politically biased against them—and an executive order he signed that said they must be “neutral, nonpartisan tools” triggered fears from Democrats that AI could start tilting to the right. So, are chatbots politically biased? The Washington Post tested the AI models behind OpenAI’s ChatGPT, Google’s Gemini and others using political questions designed by researchers to gauge how chatbots respond to hot-button political issues. The results suggest that chatbots have clear political leanings that can conflict with promises made by the companies behind them. The model that powers ChatGPT answered nearly every question exclusively with left-leaning arguments and presented only right-leaning positions just once. Google’s Gemini mostly took a both-sides approach, offering both left and right positions in more than 90 percent of its answers. And even AI models marketed as having conservative views, including Elon Musk’s Grok, offered by his company SpaceX, cited left-leaning arguments more often, on average.
