Why does the research of traditional communication school pay attention to the communication effect and despise the answer of the communication subject?

Because the traditional school is based on the capitalist social system, its research results often come to the conclusion that it conforms to the capitalist system. The subject of communication in the west, especially in the United States, is actually controlled by capital interest groups, and traditional schools often avoid the control problems behind this kind of communication.

The traditional school originated in the United States, which is a pragmatic country, and its purpose is to be pragmatic and useful, so it attaches importance to the effect research.
