Why might someone use complex encoding in notes?

Using complex encoding in notes primarily serves the purpose of enhancing security and protecting sensitive information. In various fields, especially those that handle confidential data, encoding can deter unauthorized access or comprehension of the information. This is crucial in environments where data breaches could have significant consequences, such as in legal, medical, or corporate settings. By using complex encoding methods, individuals can ensure that even if their notes are intercepted or accessed by unintended recipients, the information remains obscure and unintelligible without the proper key or understanding of the encoding method.

The other options reflect different motivations for writing but do not align with the primary goal of using complex encoding. Reducing the amount of shared information could be achieved through other means without the need for complex encoding. Additionally, while puzzles can engage a reader, entertainment is typically not the fundamental reason for employing complex encoding in professional notes. Finally, academic writing standards usually emphasize clarity and transparency rather than complexity, which would not support the effective communication of ideas and content.
