The most bias-free way to reach a conclusion
Every information source carries bias. Every AI model carries bias. The only way through is to pit them against each other — adversarially, with equal resources, multiple rounds, and full access to the internet — so their biases cancel out.
REBUTL's approach is grounded in peer-reviewed research: Mercier & Sperber's Argumentative Theory of Reasoning, Kahneman's Adversarial Collaboration, and the latest multi-agent AI debiasing research from AAAI, NeurIPS, and ICML. We combine frontier models from different providers — each with their own training data and perspectives — in a structured Oxford-style debate.
