Survivorship Bias
The tendency to focus only on successful examples while ignoring those that failed, skewing your perception of what actually works.
A cognitive bias in which attention concentrates on successful cases or survivors of a process while overlooking failures or those eliminated along the way. This distorts perception of overall outcomes, making success appear more common or inevitable than it actually is. Common in business, investing, and historical analysis.
What this means in real life
A friend raves about quitting their job to start a business, so you assume entrepreneurship is a reliable path to wealth—but you don't hear from the dozens of people whose startups quietly failed and who returned to employment.
What it isn’t
It is not simply noticing success stories or learning from winners. Rather, it's the error of drawing broad conclusions from visible successes while systematically missing the invisible failures that would change your conclusion.
Commonly misused online
People invoke it to dismiss any success story as 'just survivorship bias,' ignoring that the term describes a specific analytical error—overlooking failures—not the mere existence of winners.
