We use a number of shortcuts when we judge others. All of the following are shortcuts that we use to judge others except .
stereotyping
the self-serving bias
the halo effect
the contrast effect
selective perception

The self-serving bias.

Explanation:

In psychology, the term self-serving bias refers to the tendency we have to attribute our own successes to internal factors and to attribute our failures to external factors that we couldn't control. This bias doesn't have to do with making attributions about other people's behavior but rather about our own results.

Therefore, this wouldn't be a shortcut that we use to judge others but ourselves.
