This can lead to false conclusions in several different ways. It is a form of selection bias.<br /> Survivorship bias can lead to overly optimistic beliefs because failures are ignored, such as when companies that no longer exist are excluded from analyses of financial performance. It can also lead to the false belief that the successes in a group have some special property, rather than just coincidence (correlation proves causation). For example, if three of the five students with the best college grades went to the same high school, that can lead one to believe that the high school must offer an excellent education. This could be true, but the question cannot be answered without looking at the grades of all the other students from that high school, not just the ones who &quot;survived&quot; the top-five selection process.<br /> <br /> <br /> [[Category:Debate_resources]]<br /> [[Category:Logical Fallacies]]<br /> [[Category:Ignorance_&amp;_Misinformation]]</div> Pile
