The term epistemic feedback is a form of feedback which refers to an interplay between what is being observed or measured and the result of the observation. ref Physics and philosophy selected essays , Henry Margenau, 1978, 404 pages, p.287, webpage http books.google.com books?id qACjM08hNfQC&pg PA287 BG287 states, involves an interplay between what is being measured and the result of the measurement . ref The concept can apply to a process to obtain information, where the process, itself, changes the information when being obtained. For example, instead of quietly asking customers for their opinions about food in a restaurant, making an announcement about food quality, as being tested in a survey, could cause cooks to focus on having high quality results. The concept can also apply to changing the method of observation, rather than affecting the data. For example, if after asking several customers about food, they noted the food as generally good or fair, then the questions might be changed to ask, more specifically, which food items were most least liked. Hence, the interplay can alter either the observations, or the method of observation, or both. Viewing negative or positive effects The effects of epistemic feedback can be viewed as either negative or positive, depending on the goal of the observations. When trying to get a secret survey of results, then epistemic feedback can be seen as a negative factor which distorts the original data. However, if the goal is to improve quality, then epistemic feedback could be a positive factor to periodically report areas which need improvement. The risk comes when the feedback temporarily slants the evaluation of quality, so that long ... for feedback Some methods to compensate for epistemic feedback are to use a double blind ... the impact of short term feedback on the observed results.

Electrothermal feedback is a concept in electronics that describes the interaction of the electric current and the temperature in a device with a temperature dependent electrical resistance . This interaction arises from Joule heating . The temperature dependence of the electrical resistance is described by the derivative of the resistance with respect to temperature math dR dT math . Semiconductors typically exhibit a negative math dR dT math . Superconductors exhibit a large positive math dR dT math on the superconducting phase transition. Normal non superconducting metals typically exhibit a positive math dR dT math that decreases to zero at very low temperatures. If a device has a positive math dR dT math , an increase in temperature for example, due to a thermal fluctuation or the absorption of a photon will increase the electrical resistance math R math . If the device is biased with a constant voltage math V math , this increase in resistance will decrease the Joule power math P V 2 R math . The decrease in Joule heating will cause the device to return to its equilibrium temperature. This is known as negative electrothermal feedback, as the change in Joule heating opposes the change in temperature. If the device is instead biased with a constant current math I math , the Joule power math P I 2 R math will increase if the temperature increases. Thus the Joule heating amplifies a change in temperature, an effect known as positive electrothermal feedback. The situation is reversed for the case of a negative math dR dT math . Electrothermal feedback is important for describing the performance of several types of photodetectors such as the bolometer , the transition edge sensor , ref K.D.
