That’s compatible with information theory. You have a piece of information, the moment you encode it (turn your idea into words) that piece of information is transposed to a little different piece of information, then the channel of transportation adds a bit of noise (depends on the environment, most often literal background noise), and then the receiver decodes the to a different piece of information (turn your words into an idea of their own).

Understanding this concept is an important communication skill. Information theory gives a bunch of tools to minimize the difference between the idea in your head and the perception of the idea by your peer.

• You can add redundancy, aka say the same thing twice in a slightly different way.
• Use questions to validate your understanding.
• Have your peer use their own words.
