Read the passage given below to answer.

In our day-to day life, we assign certain causes or reasons to a person's behaviour. This process is called attribution. Broadly, causes of a person are attributed to internal and external factors. Internal factors are related to situation. With reference to success and failure, Weiner has classified causes into internal/external and stable/unstable factors. In general, people attribute success to internal factors such as their ability and hard work. However, failure is attributed to external factors such as task difficulty and bad luck. Ability/fate and hard-work/task-difficulty are considered as stable and unstable factors respectively. Stable factors refer to those causes that do not change with time. It has been observed that people have a tendency to give greater weightage to internal factors than external one. This phenomenon is called the fundamental attribution error. This tendency is stronger in some cultures than in others. Research suggests that Indians tend to make more external attributions than Americans do.
