针对德国媒介理论中存在的“媒介生产了其传输的内容”的“媒介基要主义”，克莱默尔提出了“信使模式”，主张恢复传播的“邮递原则”，将媒介视为是一个中立的、他律的信使，只负责信息的传递。虽然信使模式有着其理论上的正当性，但是将媒介视为信使，仍然深处于一种表征主义范式，媒介只是在“再现”世界而已。在巴拉德“能动实在论”视角之下，媒介的“表征”行动本身也会造成世界的重构，促使世界生成至一种新的实在。媒介更多的是在“衍射”世界，“衍射”意味着媒介是对世界的“纠缠”式“再现”。强调媒介的“纠缠”与“衍射”对于摆脱对媒介的静态理解，或者仅是将媒介视为一个不受他者干涉的能动实体有着积极意义。媒介的中介过程是一个“纠缠”的生成过程。

In response to the “media fundamentalism” in the German media theory that “the media produced the content it transmits”, Krämer proposed the “messenger model” and advocated the restoration of the “postal principle” of transmission, treating the media as a neutral and heterogeneous messenger is only responsible for the transmission of information. Although the messenger model has its theoretical legitimacy, treating the media as a messenger is still deep in a representationalism paradigm, and the media is only “representation” the world. From the perspective of Barad’s “Agential Realism”, the media’s “representation” action itself will also cause the reconstruction of the world, prompting the world to become a new reality. The media is diffracting the world, and “diffraction” means that the media represent the world through the “entanglement”. Emphasizing the “entanglement” and “diffraction” of the media has a positive meaning for getting rid of the static understanding of the media, or just treating the media as an active entity free from interference by others. The mediation process of the media is a entangled processes of becoming.
