It’s important to understand what bias is not. Bias is not fraud, as it does not involve intentional prejudice. Bias is also not random error, which creates deviation in results strictly by chance, and can be mitigated with a large enough study sample. Put simply, bias has to do with the unintentional skewing of results due to human failings such as poor trial design or unconscious wishes for desirable outcomes.
