Why is it that people do not necessarily make attributions as Kelley's covariation model predicts?

Question

Quizplus · Accepted Answer

Kelley's covariation model assumes that people have access to all relevant information about an event or behavior, which is not always the case. People may lack information or have limited information, resulting in inaccurate attributions. Additionally, people may also use other factors, such as cognitive biases or stereotypes, to make attributions instead of following the covariation model.
