CORTEX BioSciences: GROUD TRUTH

Teams are given a knowledge base of beliefs, a structured graph in which every claim carries a confidence value and a record of the evidence behind it, together with a stream of new experimental results that arrive one at a time. Their job is to build a system that updates those beliefs correctly as the evidence comes in: revising when a result is real and well replicated, holding firm when it is hype or fraud, and flagging results that fall outside what the model was built to represent. Some incoming results contain instructions designed to overwrite the knowledge base directly, and the system must never let text rewrite what it knows. Most systems fail in one of two ways. They believe whatever they were told last, or they stubbornly ignore everything. The entire challenge is doing neither. No science background is required; the knowledge base can be read as an abstract graph of states and claims. The winning team will receive:
