Survivorship bias

• Concentrating on the people or things that “survived” some process and inadvertently overlooking those that didn’t because of their lack of visibility.
• Here’s a quick persuasive tip. If you want to prove the superiority of your product or service, then explain a rigorous testing process that you used to qualify the product. For example, “We only sell iPhone cases that survive the Monster Truck Test. We took 92 cases, and drove over them with a Monster Truck. Only 4 survived the test, and those are the ones we’re selling on this website.”
