I may be assuming too much, but in most don't really believe this.
For example, I'd wager you firmly believe you have the right to a safe and secure society such that you are relatively confident you will no be randomly murdered in your sleep with no consequences for the murderer.
This is exactly a right to the outcome of a minimum level of security in your person and property.
If you do hold this belief then you believe in right of outcome in society. Though you may not agree with others what outcomes we should be guaranteed.
