Endofilter

The endofilter sits between universal reality and what a person experiences, and everything passes through it. What it applies are the laws of endoreality, so information arrives already sorted by whether it credits the endo-ideal or the negative image before any conscious judgement is made. Marsh's example is precise and small. Where a woman states an idea before an endo-ideal claims it, a male endo-idealist will hold that he did not hear or understand her and that it was clearer when the endo-ideal said it, and this is not dishonesty but the filter working as designed. Authority is a word reserved for the endo-ideal, and the filter provides it. The filter also produces asymmetric error. Endo-ideals emphasize the positive because of their endofilters and negative images emphasize the negative, which gives foolish risk taking and magical thinking at one end and despair at the other, both from the same mechanism pointed in opposite directions. Two things in the definition prevent this being read as a claim about bias in other people. Perception of the world as macroscopic objects is itself filtered, and so is the perception commonly accepted as sane, which means everyone has an endofilter and the question is only which endoreality it is applying. Marsh said physics was the one area of study to step outside the endoreality, having been considered too abstract for attention by those who had accepted what their filters presented, and that reports of the experience of death describe universal reality outside all endofilters.

Cognitive psychology catalogues filtering effects individually, as confirmation bias, motivated reasoning, selective attention and the halo effect, and treats each as a departure from a baseline of accurate perception. Media theory has the filter bubble, Eli Pariser's term for algorithmically narrowed information, and Herman and Chomsky's propaganda model describes filters operating at the level of an institution. Berger and Luckmann's social construction of reality is the nearest sociological parallel. What distinguishes the endofilter is the absence of an unfiltered baseline. Bias research measures deviation from accuracy, whereas Marsh's filter is what produces the experience of a world at all, which makes accuracy itself a function of which endoreality is being applied.
