Reference #474: Organizational Culture and Leadership
The "niceties" of social life — manners and morals, politeness, and tact — are in fact essential rules for keeping a social society intact. An important concept in this understanding is "face": a self-image of who we are, along with a degree of self-esteem.
The underlying rule of the social order is that we should protect each other's face. We must uphold each other's claims because our self-esteem is based on it. Not upholding someone's claims — for example, by not laughing at their joke — results in a loss of face for both parties. The affected party is embarrassed, and the offending party is seen to have behaved rudely, destructively, and irresponsibly.
