When Michaela is not asked to interview for the part-time job she wants at her favorite store, she says, "I guess it's all about who you know and not what you know." Michaela's perception can be attributed to the self-serving bias.

Michaela perception can be challenged by fundamental attribution error.

Explanation:

In social Psychology, fundamental attribution error, otherwise called correspondence bias or attribution impact, is the propensity for individuals to under-stress situational clarifications for a person's watched conduct while over-underlining dispositional and character based clarifications for their conduct.

For example, in one study when something bad happened to someone else, subjects blamed that person's behavior or personality 65% of the time.
