* Familiar to most people in a particular culture: This includes basic facts, historical events, and well-known concepts.
* Readily verifiable: The information can be easily found in multiple sources.
* Not controversial or disputed: There is general agreement about the accuracy of the information.
Examples of common knowledge:
* The Earth is round.
* The United States declared independence in 1776.
* Water boils at 100 degrees Celsius.
When to reference common knowledge:
* If there is any doubt about the information: If you are unsure whether something is considered common knowledge, it's best to cite a source.
* When writing for a specific audience: What is common knowledge to one group may not be to another. Consider your audience when deciding whether to reference information.
* To avoid plagiarism: Even if information is common knowledge, it's important to avoid presenting it as your own original work.
In summary:
While common knowledge generally does not require referencing, it's important to be aware of the nuances and to use your best judgment. If you are unsure, it's always better to err on the side of caution and cite a source.
