Art works are optimized for either ATTENTION, or TRUTH. The rest is all a matter of interpretation.
Interpretation is never objective.
"All things are subject to interpretation. Whichever interpretation prevails at a given time is a function of power and not truth." Friedrich Nietzsche
When it comes to power, its inherent needs and the set of incentives driving it, controlling and maximizing attention becomes a primary resource, while truth is mostly a distraction.
