Shannon-Weaver Model
Updated 2026-08-22
INTRODUCTION
English translation pending.
CORE DEFINITION
The Shannon-Weaver model, developed by Claude Shannon and Warren Weaver, abstracts communication into a chain of source, encoder, channel, decoder, and destination, and introduces noise as any factor that interferes with the signal. Its core claim is that decomposing the process into analyzable stages reveals where meaning is lost, since distortion can enter at encoding, in the channel, or at decoding, and noise is semantic as well as physical. The condition is that sender and receiver share context for decoding to succeed at all.
SCAFFOLDING EFFECT
Reduce cognitive load
- Decompose the chain: name the source, encoded signal, channel, decoder, and destination before analyzing any failure. - Hunt the noise: locate whether the interference is physical or semantic. - Close the loop: check that the decoded message matches the intended one and feed back corrections.
Anchor fast decisions
The model formalizes communication as source, encoder, channel, decoder, and destination and introduces noise, which shows concretely how a message is distorted at every stage of transmission and turns the passing of meaning into a measurable process rather than an assumption.
