Introspection Illusion

What is the introspection illusion?

The introspection illusion is the tendency to give too much weight to one’s own thoughts and intentions, relative to observable behavior, when explaining oneself—while relying more on behavior when judging other people. Access to a conscious thought does not necessarily reveal the process that caused a judgment.

Example of the introspection illusion

Imagine explaining your own late arrival by what you intended—“I really meant to be on time”—while explaining someone else’s lateness by the behavior alone. Your intention is information, but it does not erase what happened or fully explain why.

The introspection illusion and the bias blind spot

Pronin and Kugler found that teaching participants about limits of introspection reduced their measured bias blind spot. This does not show that awareness permanently removes all bias. Compare what you say about your motives with what you actually did, and consider outside feedback.

Naive realism concerns treating one's own view of the world as an objective reading of reality.
