information that adds value to a decision is productive, and is measured according to the amount of work it reduces

information that repeats value is predictive

information that fails to repeat value is fiction

and information having only entertainment value is consumptive

for information that describes how to achieve a previously-impossible outcome, the productive value is infinity

and for information that repeats for its recipient how to achieve an outcome they already have knowledge of, the productive value is zero (predictive)

systemaccounting empowers humans by maximizing the circulation of productive value within the economy
