A common sense error in a novel refers to the plot or setting that does not conform to facts or common sense. These mistakes may mislead the reader or make the novel lose its original meaning. Here are some common mistakes in novels: 1. Temporal error: The characters and events in the novel usually take place in a relatively fictional space-time, but there are often situations where time jumps or the passage of time is abnormal. For example, the character experienced many things in an hour, which was impossible in reality. 2. Character setting error: The characters in the novel usually have specific appearance, personality, skills, and other characteristics, but sometimes these characteristics do not conform to the facts. For example, a character should have a specific class, but they chose a non-professional class. 3. Geography errors: Fictions often involve fictional geographical areas, but the location and characteristics of these areas sometimes do not conform to reality. For example, a character's city should be in a fictional world, but its location was in reality. Plot setting errors: The plot in the novel is usually based on the thoughts and actions of the characters, but sometimes there are illogical situations in these settings. For example, a character might make some decisions without any hints, which would be impossible in real life. 5. Logical errors: The plot and characters in the novel are usually constructed through logical reasoning, but sometimes logical errors occur in the process of reasoning. For example, a character might make some decisions without any hints, but these decisions are unreasonable in real life. These common sense mistakes may negatively affect the quality of the novel, so authors and editors should avoid them as much as possible.
