Abstract

What does the Texan sharpshooter, the World War 2 American air force, The Taj Mahal, cherry farming, and dentistry have in common? They have all been the subject of Survivorship bias. This paper will discuss the concept of survivorship bias in research by using examples of flaws in study designs or interpretation of data. It aims to serve as a caution to practitioners of the need to be aware and critical when reading literature and manufacturers' reports before making decisions regarding materials choices and treatment protocols to follow
