Hostile attribution bias is the tendency to interpret the ambiguous behavior of others as hostile. Under hostile attribution bias, people assume that others have negative intentions towards them and want to hurt them, even when others have no such intentions.

As a result, people who exhibit hostile attribution bias also tend to react aggressively, causing problems in their relationships with others.

What is hostile attribution bias?

Hostile attribution bias is a type of cognitive bias where individuals tend to interpret the behavior of others in various situations as threatening, aggressive, or both. More specifically, it is an attribution bias that stems from wondering about the cause of other people’s behaviors, similar to self-serving bias.

Hostile attribution bias occurs during the process of social information processing. This is a series of steps that starts with perceiving and deciphering social cues (e.g., others’ facial expressions) and ends with choosing a suitable response in social interactions (e.g., a greeting).

People who make hostile attributions assign hostile meaning to ambiguous cues and situations, while people who do not exhibit this type of bias interpret the same behavior as non-hostile or non-threatening. People who make hostile attributions often feel threatened, and they respond with aggression. Because their perception is biased (and in reality the other person means no harm), their aggressive response is usually viewed as inappropriate.

Why is hostile attribution bias a problem?

Hostile attribution bias is associated with violent behavior. Although it was initially observed in children, studies show that there is a strong association between this bias and aggressive behavior that cuts across age, gender, and other factors.

Individuals who consistently exhibit hostile attribution bias in their early years are more likely to react aggressively toward others later in life. This aggression can be in the form of physical, verbal, or more indirect violence, such as spreading rumors in order to damage someone’s reputation.

Because of the strong link between hostile attribution bias and aggression, various interventions target hostile attribution in order to prevent aggression by training individuals to correctly identify the intentions of others.

What causes hostile attribution bias?

Hostile attribution bias is caused by cognitive schemas, or frameworks that individuals use to organize knowledge about the world and interpret information. These schemas are formed through our interaction with the world.

Negative early-life experiences, such as harsh parenting or exposure to a violent role model, are encoded as schemas or patterns of behavior. These are then retrieved when the individual is faced with an unclear social situation. Because of these negative schemas, individuals assign hostile meaning to others’ intentions.

More specifically, negative schemas may lead to errors in how individuals perceive and interpret social situations, but they may also prevent them from generating a range of possible responses and choosing the most appropriate. Such errors result in hostile attribution bias.

For example, children who are teased at school or experience corporal punishment at home may interpret another child bumping into them on the school playground as intentional, even if it was accidental.

Hostile attribution bias example

Hostile attribution bias can help explain why some people have a hard time giving others the benefit of the doubt and instead lose their temper.
