deliberate vagueness

Deliberate vagueness can have three major strategic payoffs:

Greater Longevity: If you stay abstract and employ lots of symbolisms, your text has higher chances of surviving many generations. Religious leaders do this all the time.

Wider Appeal: If you use proxies rather than saying exactly what you want to say, your text will admit a wider set of interpretations and thereby enjoy a greater likelihood of being related to. Poets do this all the time.

Less Accountability: By saying lots of things but actually saying nothing you can evade accountability altogether. Politicians do this all the time.
