What is outcome bias?
This is an error made in evaluating the quality of a decision when the outcome of that decision is already known. It leads to the tendency to keep doing things the way you are doing them now because you think it led to positive results.
Example in the hiring process.
Outcome Bias makes us still use unstructured interviews in the application process, because look, we hired some great talent because of it this hiring practice. However, you don’t know if you could have hired greater talent by applying a different practice.
