In finance, survivorship bias is the tendency for failed companies to be excluded from performance studies because they no longer exist. It often causes the results of studies to skew higher because only companies that were successful enough to survive until the end of the period are included.

Survivorship bias (or survivor bias) is a cognitive fallacy in which, when looking at a given group, you focus only on examples of successful individuals (the "survivors") in the selection process rather than the group as a whole (including the "non-survivors").
7 Lessons on Survivorship Bias that Will Help You Make Better Decisions
Survivorship bias describes the error of looking only at subjects who've reached a certain point without considering the (often invisible) subjects who haven't. In the case of the US military they were only studying the planes which had returned to base following conflict i.e. the survivors.

Survivorship Bias. Jun 28, 2021. In World War II, the US Military examined damaged aircraft and concluded that they should add armor in the most-hit areas of the plane. Abraham Wald at Columbia University proved this was the wrong conclusion, that instead, adding armor to the least hit areas of the aircraft is more effective.

In statistics, survivorship bias can be defined as a form of sampling bias in which the observations taken at the end of a period of study do not conform to the random subset of the observations made at the beginning of the study.
Survivorship bias when failure gets Ness Labs
Survivorship bias is a form of selection bias. It occurs when a dataset only considers existing (or "surviving") observations and fails to consider observations that have ceased to exist.

During WWII, countries had to solve many mathematical and strategic tasks in order to succeed during the war. One of those difficult assignments was to find ways of improving aircraft so they would be more resistant to enemy fire. While statisticians struggled to find the best way to protect the planes, one man named Abraham Wald had a genius idea that is implemented in many places to this day.

Survivorship Bias 101 Black Belt in Thinking
Survivorship bias, or survivor bias, occurs when you tend to assess successful outcomes and disregard failures. This sampling bias paints a rosier picture of reality than is warranted by skewing the mean results upward. Survivorship bias is a sneaky problem that tends to slip into analyses unnoticed.
How to lie with big data Medium
Survivorship bias is a type of selection bias where the results, or survivors, of a particular outcome are disproportionately evaluated. Those who "failed", or did not survive, might even be ignored. Focusing on the survivors can result in a false, or incorrect, estimate of probability.
