The dead can’t tell their stories. Even when their accounts are documented, they are often given less credence than the accounts of survivors who still exist to share theirs. Simply put, survivorship bias is a logical fallacy in which we concentrate on the accounts of those who have made it past some criteria and overlook the accounts of those who did not. The error is compounded as conclusions are drawn that suggest that success is due to some characteristic shared by the successful instead of extraneous variables or random chance.
I most often see this bias play out in three ways:
- “The secret to a long life” stories
- “I did XYZ as a child, and I turned out fine” stories
- “Rags to riches” stories
Even though some of these stories may be shared with a humorous intent, there are plenty of examples where people believe that they are drawing accurate conclusions about success based on a selective review of attempts in pursuit of that success.

When it comes to medical science and health, be extra careful about the sources you share from, who is attaching their name to the articles, and what research they are linking to. There is a dangerous habit of media outlets of all sizes taking the results of a very preliminary study and making wildly exaggerated claims about how the possible benefits.
10 things to watch out for when interpreting research
Last Week Tonight with John Oliver did a great breakdown of how wild headlines can get when cherry-picking from research back in 2016. This focuses mostly on major mainstream media outlets not to mention the barrage of small, pseudo-anonymous “health” websites sharing dubious information with little substantiation.
It’s not enough to have sources to support your claims; they must be good sources. Good science is that which is overwhelmingly supported by scientists throughout the field of study. Good science is not a single study, conclusion, or data point that happens to support a preconceived idea.
The greater challenge is to be truly open-minded to changing or modifying our practices or beliefs when presented with new, substantiated information. Appeals to antiquity or tradition are NOT good reasons for continuing to practice or believe something, particularly in the fields of science, especially when those long-held practices were formed in the absence of newer, more relevant information.
Is your source CRAAP? The CRAAP test was designed by librarians at CSU Chico to examine a source of information. It looks at the areas of Currency, Relevance, Authority, Accuracy, and Purpose as a means of separating the good from the bad.
Sharing a picture with words on it on Facebook because you agree with it fails this test. That is most often when one fails to examine accuracy and purpose. Sure, perhaps you’re very upset that Pepsi didn’t include the words “under God” in the Pledge on its packaging, but that doesn’t change the reality that it never happened. Who created that deliberately misleading image with incorrect information? Why?
Just as it is important that credible news have an author’s name attached to show that a reputation is linked to the accuracy of the information within, we all also have reputations being formed by the types of information we attach our name to when we share it. Make sure you attach your name to information that won’t damage your credibility.
