self-serving bias

Explanation:

Self-serving bias is a type of cognitive bias that involves attributing our successes to internal characteristics and blaming faults on external forces.  When we are taking in information and making judgments about the world and events around us, we do not always interpret these things objectively.  Cognitive biases such as self-serving bias often interfere with how we evaluate information and reach decisions.
