Depressive realism is the proposition that people with depression actually have a more accurate perception of reality, specifically that they are less affected by positive illusions of illusory superiority, the Locus of Control and optimism bias. The concept refers to people with borderline or moderate depression, suggesting that while non-depressed people see things in an overly positive light and severely depressed people see things in overly negative light, the mildly discontented grey area in between in fact reflects the most accurate perception of reality.
