When a group is more effective and integrated in putting the needs of the group before its personal needs, it is an example of Social Identity Theory.
What is Social Identity Theory?
It is an approach developed by psychologists Henri Taffel and John Turner that identifies as social identity the need that an individual has to belong to a certain social group, based on similar characteristics, which allows self-comparison.
