Social comparison
Also known as: Social comparison theory
We evaluate ourselves by measuring against other people.
What it means
Social comparison is the process by which people assess their own abilities, opinions, and outcomes by comparing themselves with others, especially when objective standards are absent. Festinger's original theory held that the drive to evaluate the self is satisfied through comparison, ideally with similar others, and later work distinguished upward comparisons (with the better-off) from downward comparisons (with the worse-off), which have systematically different effects on motivation and well-being. Upward comparison can inspire and inform but can also breed envy and dissatisfaction, while downward comparison can comfort and protect self-esteem but can also breed complacency, so the consequence depends on the direction, the relevance of the comparison, and the person's goals. The process underlies status competition, relative-income effects on happiness, and the well-documented harms of curated social-media feeds, where relentless upward comparison erodes mood. It is also the engine of norm-based nudges, which work by showing people how their behavior stacks up against a peer group. It matters because so much of human satisfaction is relative rather than absolute, which means well-being tracks one's standing among others as much as one's actual circumstances.
Examples
An energy report showing how your usage compares with your neighbors' nudges heavy users down through downward social pressure.
Learning that a colleague doing the same job earns more can sour a salary you were perfectly content with an hour earlier. The pay did not change, only the comparison.
Half an hour scrolling other people's holiday photos leaves someone dissatisfied with a perfectly good week off, because a feed is a highlight reel measured against an ordinary Tuesday.
First described in Leon Festinger (1954).
