As stated above, a third issue with the Shannon-Weaver model is its lack of attention to the meaning behind messages. The simplistic Shannon-Weaver model is inadequate as a communication theory since it does not address the meaning of the communication. Rather, it assumes that meaning is inherent in the message and readily available to the receiver. Yet the inclusion of the concept of meaning in the theory, which must necessarily play a part in the encoding and decoding steps, has important implications for the study of human communication. Broadening these concepts beyond simple physical interpretations has provided a starting point for addressing the complex and dynamic nature of human communication.
