Unlike many other emotions, embarrassment must be learned. Infants know nothing of this emotion, and parents often use the threat of embarrassment to teach young children correct and incorrect behavior: “If you say that in public, you’ll embarrass yourself,” we say to the toddler with a penchant for scatological chitchat. Embarrassment is also a social emotion; its occurrence requires the real or imagined presence of others. Belch at a dinner party and you will likely feel embarrassed; do it while home alone and you’re unlikely to feel abashed. Because it is a learned behavior grounded in social relations, embarrassment is a kind of barometer for a society’s notions of civility.
