Actor-Observer Bias – when you blame circumstances for yourself but personality for others

Electric editorial collage illustrating Actor-Observer Bias

Late to a meeting? Well, traffic was terrible! Someone else is late? They must be irresponsible. That’s Actor-Observer Bias – the tendency to blame our own behavior on external circumstances while attributing others’ actions to their personality.

Where it can show up


- Work & career – if a colleague fails a task, they’re lazy; if you fail, it’s because you didn’t have enough time.
- Driving – other drivers are reckless, but when you make a mistake, it was ‘necessary.’
- Relationships – if your partner is moody, it’s ‘just who they are’; if you’re moody, it’s because you had a tough day.

A practical countermeasure


- Apply the same standards to yourself and others – people face tough situations too.
- Consider the context – personality isn’t always the cause of behavior.
- Flip the situation – how would you explain your own behavior in the same case?
