What is conservatism bias?
Conservatism Bias is the tendency to prefer existing evidence over new evidence that might change your view on something, which is caused by a resistance to change your opinion about something. The mere exposure effect also ties in closely with this bias.
Example in the hiring process.
Almost every hiring manager and recruiter knows or should know by now that CVs and unstructured interviews have little to no predictive value and can easily lead to poor, biased decision-making. Yet, we tend to ‘ignore’ the evidence for this because we don’t want to change something we’re doing this way for such a long time already.
