Concept
Introspection illusion

Overview
The introspection illusion is a cognitive bias in which people wrongly think they have direct insight into the origins of their mental states, while treating others' introspections as unreliable. The illusion has been examined in psychological experiments, and suggested as a basis for biases in how people compare themselves to others. These experiments have been interpreted as suggesting that, rather than offering direct access to the processes underlying mental states, introspection is a process of construction and inference, much as people indirectly infer others' mental states from their behaviour.
When people mistake unreliable introspection for genuine self-knowledge, the result can be an illusion of superiority over other people, for example when each person thinks they are less biased and less conformist than the rest of the group. Even when experimental subjects are provided with reports of other subjects' introspections, in as detailed a form as possible, they still rate those other introspections as unreliable while treating their own as reliable. Although the hypothesis of an introspection illusion informs some psychological research, the existing evidence is arguably inadequate to decide how reliable introspection is in normal circumstances.
In certain situations, this illusion leads people to make confident but false explanations of their own behaviour (called "causal theories") or inaccurate predictions of their future mental states.
Correction for the bias may be possible through education about the bias and its unconscious nature.

It is hardly necessary to add, that when the inductive inference is of any but the most direct and obvious nature—when it requires several observations or experiments, in varying circumstances, and the comparison of one of these with another—it is impossible to proceed a step, without the artificial memory which words bestow. Without words, we should, if we had often seen A and B in immediate and obvious…

We then revise our conceptual scheme so as to preserve the general trust in the symbolic reference, while relegating definite details of that reference to the category of errors. Such errors are termed ‘delusive appearances.’ This error arises from the extreme vagueness of the spatial and temporal perspectives in the case of perception in the pure mode of causal efficacy. There is no adequate definition of…

It remains to point out briefly the bearing of these results on what is called "the method of introspection." We are sometimes assured that introspection has discarded the belief in a separate mental stuff or subject-matter, but there is ground for the suspicion that such protestations are made in the same spirit that we affirm our belief in the Ten Commandments or the Golden Rule, with no thought of being taken…
