[1] That is, someone's subjective judgments are "projected" to be inherent properties of an object, rather than being related to personal perception.
In a second "negative" form of the fallacy, as described by Jaynes,[1] occurs when someone assumes that their own lack of knowledge about a phenomenon (a fact about their state of mind) means that the phenomenon is not or cannot be understood (a fact about reality; see also Map and territory.)
Jaynes used this concept to argue against Copenhagen interpretation of quantum mechanics.
[2] He described the fallacy as follows:[1] [I]n studying probability theory, it was vaguely troubling to see reference to "gaussian random variables", or "stochastic processes", or "stationary time series", or "disorder", as if the property of being gaussian, random, stochastic, stationary, or disorderly is a real property, like the property of possessing mass or length, existing in Nature.
Indeed, some seek to develop statistical tests to determine the presence of these properties in their data...Once one has grasped the idea, one sees the Mind Projection Fallacy everywhere; what we have been taught as deep wisdom, is stripped of its pretensions and seen to be instead a foolish non sequitur.
