This document discusses various barriers to effective communication. It identifies 10 main barriers: semantic barriers due to differing meanings; physical barriers like noise that distract from messages; lack of planning that prevents clear messaging; false assumptions that lead to misunderstandings; ambiguity that causes confusion; distortion that changes a message's meaning; passing judgements that criticize speakers; implied meanings beyond the literal definition of words; lack of trust between parties; and technological barriers like limited access to communication channels. Specific examples are provided to illustrate each of these 10 common barriers to successful transmission and understanding of information between individuals or groups.
