Looking-glass self
Etymology
Coined by American sociologist Charles Horton Cooley in "Human Nature and the Social Order" (1902). "Looking-glass" is an old English term for a mirror. Cooley described a three-step loop: we imagine how we appear to others, imagine their judgment, and then feel a resulting emotion. Flagged as a coinage.
noun phrase · /LOOK-ing-glas SELF/
The idea that we form our self-image from how we imagine others see us.
What it names
The mirror-in-other-people’s-eyes through which identity is built — handy for seeing how much of "you" is a reflection.
Example
Teenagers are ruled by the looking-glass self, endlessly refracting themselves through what they imagine classmates are thinking.
Related idea
Compare the halo effect, which is how we misjudge others; the looking-glass self is about how their imagined judgments construct us.
