  The Equal Weight View has also been motivated by way of analogies.  Of particular prominence are analogies to thermometers. Thermometers take in pieces of information as inputs and given certain temperature verdicts as outputs. Humans are a kind of cognitive machine that takes in various kinds of information as inputs and give doxastic attitudes as outputs. In this way, humans and thermometers are analogous. Support for the Equal Weight View has come from examining what it would be rational to believe in a case of peer thermometer disagreement. Suppose that you and I know we have equally reliable thermometers and while investigating the temperature of the room we are in discover that our thermometers give different outputs (yours reads ‘75’ and mine reads ‘72’). What is it rational for us to believe about the room temperature? It seems it would be irrational for me to continue believing it was 72 simply because that was the output of the thermometer that I was holding. Similarly, it seems irrational for me to believe that your thermometer is malfunctioning simply because my thermometer gave a different output. It seems that I would need some information independent from this ‘disagreement’ to discount your thermometer. So, it appears that I have been given a reason to believe that the room’s temperature is not 72 by learning of your thermometer, that this reason is as strong as my reason to believe it is 72, and that this reason is only defeated by independent considerations. If the analogy holds, then we have reason to accept each of the three theses of the Equal Weight View.
