Explanation:

According to social identity theory, one implication of identifying with a particular group is that the closer that individuals feel to a group (the “in-group”), the more uniform their behavior will be and the more likely they will regard members of other groups (“out-groups”) as being cut from the same cloth.

manifest functions are the recognized and intended consequences of any social pattern, while latent functions are those unrecognized and unintended consequences. to analyze the manifest functions of any social institution, we have to study its contribution to the continuation of a group, community, or society.
