 Collins (1985) articulated a widely discussed problem that is now known as the experimenters’ regress. He initially lays out the problem in the context of measurement (Collins 1985: 84). Suppose a scientist is trying to determine the accuracy of a measurement device and also the accuracy of a measurement result. Perhaps, for example, a scientist is using a thermometer to measure the temperature of a liquid, and it delivers a particular measurement result, say, 12 degrees Celsius.
