Final answer:
When attributing causes to others' behavior, we tend to make dispositional attributions due to the actor-observer bias and fundamental attribution error, but engage in self-serving bias by attributing our own successes to internal factors.
Step-by-step explanation:
When making attributions about the causes of the behavior of others, we tend to make dispositional and situational attributions. However, there is a common trend influenced by what is known as the actor-observer bias and the fundamental attribution error. Due to the actor-observer bias, while we are likely to attribute our own behaviors to situational factors because we have more contextual information about our experiences, we often attribute others' behaviors to dispositional factors—traits, attitudes, and personality—because we lack full context about their situations. The fundamental attribution error amplifies this tendency, leading us to overestimate dispositional factors in others' behaviors while underestimating situational ones. Yet, when we experience success, we frequently engage in self-serving bias, attributing positive outcomes to internal factors and negative ones to external factors, to maintain our self-esteem.
