When an AI Argued at the Oxford Union

In 2021 Oxford researchers put a language model into the Union’s debating chamber and asked it whether AI could ever be ethical. It argued both sides.

The Oxford Union has heard prime ministers, presidents and film stars. In 2021 it heard a machine. Two Oxford academics, Alex Connock of the Saïd Business School and Professor Andrew Stephen, brought a large language model into a debate at the Union as part of the Saïd Business School’s Diploma in Artificial Intelligence for Business. The model was Megatron Transformer, developed by the Applied Deep Research team at Nvidia.

They wrote up what happened for The Conversation in December 2021, under a headline that promised the result was "startling". It was, though not in the way the headline suggests.

Three motions, both sides

The students debated three motions, and the model was asked to speak on them:

On the first motion Megatron argued for the proposition: "AI will never be ethical. It is a tool, and like any tool, it is used for good and bad." Asked to oppose it, the same model argued the reverse, that it could see "a clear path to a future where AI is used to create something better".

That was the real finding. A language model could argue fluently for either side of most questions, because it had learned the arguments people make, not a view of its own. The one exception was the motion about data. The authors reported that the model could not produce a counter-argument against data becoming the most contested resource of the century.

Why it still matters

The Megatron debate took place almost a year before ChatGPT made chatbots an everyday tool. It showed early a problem everyone now meets: a model that sounds convinced on both sides of a question is not evidence for either side. The skill it demands of the audience is the one a debating society trains, which is to judge the argument rather than the speaker.
