Actor-Observer Bias

Verified by World Mental Healthcare Association

The actor-observer bias refers to individuals attributing their own behavior to situational factors and others’ behavior to personal traits. This bias can result in misunderstandings and conflicts, adversely affecting mental health functioning and overall well-being.

What is Actor-Observer Bias?

The actor-observer bias is a common bias 1 Koenig, A. (2013). Actor‐Observer Bias. 19–20. Available from: observed in social interactions and perceptions. When individuals are the “actor” in a situation, they tend to focus on the situational context that influenced their behavior, leading them to attribute their actions to external factors such as circumstances, pressure or other people’s influence.

On the other hand, when individuals are the “observer” and interpret the behavior of others, they tend to attribute their actions to internal characteristics or dispositional factors, such as personality traits or inherent qualities.

For example, when individuals are running late 2 Nadelhoffer, T., & Feltz, A. (2008). The Actor–Observer Bias and Moral Intuitions: Adding Fuel to Sinnott-Armstrong’s Fire. Neuroethics, 1(2), 133–144. Available from: , they tend to attribute their behavior to external factors, such as traffic congestion or unexpected circumstances, as the actor. However, as observers, they often attribute others’ behavior to personal traits like laziness or lack of responsibility. Research indicates that women are 3 Marsh, R. L., Cook, G. I., & Hicks, J. L. (2006). Gender and orientation stereotypes bias source-monitoring attributions. Memory (Hove, England), 14(2), 148–160. more likely than men to use these external attributions.

Causes of the Actor-Observer Bias

Some causes of 4 The Influence of Actor Observer Bias on Attributions of Other Drivers. (n.d.). ResearchGate. Available from: the actor-observer bias include:

1. Perceptual Differences

In everyday situations, individuals tend to focus more on their thoughts, feelings, and the circumstances surrounding them when considering the reasons behind their actions. However, when it comes to understanding why others behave the way they do, people often pay more attention to what they can directly see and observe about those individuals.

2. Informational Differences

People have more direct access to their thoughts, emotions, and situational factors compared to the limited information available when observing others. This information asymmetry can lead to biased judgments and attributions.

3. Motivational Differences

Motives play a significant role in actor-observer bias, including the need to enhance or protect one’s self-esteem. This bias is particularly evident in negative situations where blame-worthy behavior occurs. To protect their self-esteem, individuals tend to point to external factors, placing the blame on others rather than accepting full responsibility for their own behavior.

Impact of the Actor-Observer Bias on Mental Health

The impact of the actor-observer bias on mental health 5 Robins, R. W., Spranca, M. D., & Mendelsohn, G. A. (1996). The actor-observer effect revisited: effects of individual differences and repeated social interactions on actor and observer attributions. Journal of personality and social psychology, 71(2), 375–389. can be significant and includes:

  1. As individuals attribute their behavior to external factors but attribute the behavior of others to internal traits it can create misunderstandings and interpersonal conflicts.
  2. By failing to consider external factors influencing others’ actions, individuals may struggle to understand and empathize with their experiences.
  3. When people consistently attribute their behavior to external factors, they may struggle to take personal responsibility for their actions.
  4. Misattributing others’ behavior to internal traits can fuel negative judgments, hostility, and passive aggression, causing elevated levels of stress and anxiety in social situations.
  5. When individuals consistently attribute others’ behavior to internal traits, it can create a lack of social support and loneliness.
