Why is "Ultimate attribution error" trending?

Wikipedia Overview

The ultimate attribution error is an attribution error made when making in-group and out-group attributions, resulting in in-group favoritism. The error occurs when attributions of outgroup behavior are more negative and attributions of ingroup behavior are more positive. As a cognitive bias, the error results in negative outgroup behavior being more likely to be attributed to factors internal and specific to the actor, such as personality, and to attribute positive behaviors to external factors, such as the context the behavior is exhibited in. The opposite effect is seen for in-group members as they are more likely to attribute their positive acts to dispositional factors, and their negative acts to situational factors. Also, in-group members will 'explain away' out-group success to external factors such as luck or circumstance. The bias reinforces negative stereotypes and prejudice about the out-group and favouritism of the ingroup through positive stereotypes. The Ultimate attribution error is an example of a cognitive bias that shows cross cultural differences, showing up more strongly for individuals in Western cultures than Eastern Cultures.
