Initial display (before any tests made) for a fault diagnosis problem, showing a network of water storage tanks with water flowing from left to right and observations of clean (C) and rusty (R) water flowing in pipes. The overlays (which were not shown to participants) show the reduced fault set after using general backtracking (solid straight lines), elimination (dashed lines), and IBE (circle) based on the network outputs at the beginning of the problem. The pipe numbers and tank letters were not shown to participants. The rusty tank is circled
