Bragging: Researchers find self-promotion often backfires

A new study from City University London, Carnegie Mellon University, and Bocconi University found that self-promotion or humblebragging often elicits a negative response. Self-pro promoters tend to overestimate others' positivity and underestimate their negativity, leading to excessive bragging with the opposite effect.
