What are the advantages and disadvantages of self serving biased?

Self-serving bias, the tendency to attribute positive outcomes to one's own actions and negative outcomes to external factors, has both advantages and disadvantages. On the positive side, it can boost self-esteem and motivation, helping individuals maintain a positive self-image and resilience in the face of failure. However, it can lead to a lack of accountability, hinder personal growth, and damage relationships, as individuals may refuse to acknowledge their own shortcomings. Ultimately, while self-serving bias can foster confidence, it may also distort one's perception of reality and impede constructive feedback.
