Does the amount of information in a message depend on how new the message is to the recipient?

Depends. Different people who have received the same message have different assessments of its information capacity, that is, the amount of information contained in it. This is due to the fact that people’s knowledge of the events, the phenomena referred to in the message, before receiving the message were different. Therefore, those who knew little about this will consider that they received a lot of information, while those who knew more may say that they did not receive information at all.
