How does an editor know when to cut?

In the video essay by Tony Zhou, he explains how an editor knows when to cut to another shot of a scene. In this essay, Zhou explains how it almost feels natural to cut at certain points. When an editor is examining a scene, they feel an unexplainable rhythm to the dialogue: they just know when to cut the scene. Zhou also explains that this rhythm is similar to the rhythm that we feel in an everyday conversation. The brain knows when to start and stop talking, recognize the persons emotions, and how to react to certain words. Editors need to be able to put themselves in the character's shoes and feel that natural rhythm. The famous editor Thelma Schoonmaker, editor of the film Raging Bull, said that some scenes could be held for longer or shorter to give the viewer a sense of uneasiness. When this is done, it messes with the viewers idea of rhythm in the scene, giving that scene more of an emotional value if done right.
