Answer:
the belief-bias effect.
Step-by-step explanation:
A belief is simply having faith, trust on something that exists or is true usually does not need proof.
Bias is simply a prejudice usually for something, someone, beliefs or against one person, something, beliefs group and others.
the belief-bias effect usually occurs when people accept only the evidence that is in line with their belief (that is in conformity) and therefore rejecting,ignoring any beliefs or evidence that does not fall into that line.
