|Pollock's gas chamber, philosophy: is a thought experiment by J.L. Pollock. A toxic green gas is introduced from time to time into a closed test setup. For protection, a sign is attached which is visible through a window in the door "Do not enter if this sign discolors to green”. If there is a lot of gas, however, the sign is no longer visible. For this reason, a monitor is attached to the outside in connection with a camera inside. This monitor is unfortunately only in black and white ... Variant) a green colored color monitor is brought by the caretaker in accordance with its black and white memory of the sign. (See W. Poundstone, “Labyrinths of Reason”, 1988).

Pollock's gas chamber/Poundstone: one can reject belief in more than one way - 1. the light looks green (without information about the color of the gas) - 2. Usually things have the color that they have on the screen, therefore there is color TV - Vs: the second is even weaker than the first - so there is even a third reason in addition to the sign next to the door - be right for the wrong reasons - refutation: a) rejecting: simply says that a belief is false - b) undermining: that belief is invalid - e.g. if you discover that you are a brain in a vat, which is an undermining truth over all beliefs about the world - N.B.: the belief could then still be true - undermining better than rejecting truth.
Prisoners Paradox/knowledge paradox: (unexpected execution) the set of beliefs generates its own undermining truth - so there are refutations of refutations.
