In terms of confidentiality, what is true about letters?

Letters are considered confidential because they often contain personal, sensitive, or proprietary information intended solely for the recipient. This confidential nature is established through expectations of privacy when communicating through letters, whether they are personal correspondence or business communications.

In many cases, the sender and recipient have an implicit understanding that the information shared is not to be disclosed to others. This is especially true in professional settings, where letters can include sensitive business strategies, financial information, or private correspondence. The expectation of confidentiality helps to maintain trust and privacy between the parties involved.

While there are cases where letters can be considered public documents (such as legal documents that are filed with a court), this is not the norm for personal or most business correspondence. Additionally, letters are not usually shared widely unless explicitly stated, as confidentiality is typically a prerequisite in written communication. Lastly, while some letters could have legal implications, confidentiality does not directly relate to whether a letter is legally binding, but rather to the trust and privacy it represents between the communicating parties.
