A more thorough explanation:

Definition: Selective disclosure is when someone reveals only part of a private conversation or information, usually because the disclosed part benefits them while the rest could be harmful. This can result in a partial loss of privacy for all related conversations.

Example: Imagine two friends, Alice and Bob, are talking about a secret project they're working on. Alice tells Bob some details about the project, but not everything. Later, Bob uses the information Alice gave him to get ahead in the project, while keeping the rest of the conversation secret. This is an example of selective disclosure.

Explanation: In this example, Alice and Bob had a private conversation about their project, which they expected to keep confidential. However, Bob chose to reveal only part of the conversation to benefit himself, while keeping the rest hidden. This is selective disclosure, as Bob chose to disclose only the parts that helped him, while withholding the rest.
