Plain language
A classical philosophical image of prisoners only seeing shadows on a wall, used as a metaphor for AI systems reasoning over corrupted or limited inputs.
As stated in the literature
Plato's allegory used in the Oracle Poisoning paper to frame how AI agents may reason in detail from impoverished or corrupted observational data.
Why it matters: The metaphor sharpens the question of what an agent can know when its only window onto the world has been tampered with.
For example, an agent reasoning from a corrupted knowledge base is like a prisoner inferring the world from manipulated shadows.
