Background & History
The concept of **attribution bias** originates within the field of psychology, specifically in studies on human cognition and decision-making. Early explorations were rooted in social psychology, where researchers examined how people attribute motives and intentions behind behaviors. Key milestones include the development of theories by psychologists like Fritz Heider (1958) and later expanded by attribution theorists such as Harold Kelley and Lee Ross. These studies laid the foundation for understanding systematic patterns in judgment, influencing broader fields like behavioral science and artificial intelligence.

Why Notable
Attribution bias is notable because it explains why people often misjudge causes of actions—whether in personal relationships, workplace dynamics, or social interactions. This cognitive distortion can lead to misunderstandings, biased decisions, and even unintended consequences in communication and conflict resolution. Its study has implications across psychology, economics, and AI development, where accurate causal reasoning is critical.
