👉 Improvability refers to a property or characteristic of something that cannot be altered, changed, or determined. It is often associated with phenomena like randomness or unpredictability, which are characteristics that can only be observed through observation and experimentation. In other words, it's a property that cannot be fully controlled by human beings, making it impossible for someone to predict or control it. This concept has been explored in various fields such as psychology, sociology, and astrophysics.
