Coherency and relevancy are extremely important for any story.

But it is difficult to maintain both for an extended period of time for any given audience. At a certain point, the story will either cease to be coherent or it will lose relevance.

Ambiguity and contradiction are the enemy of coherence. Struggling to maintain coherency in the face of ambiguous or contradictory information takes a fair bit of mental gymnastics to keep the story going. Contorting information to fit a narrative to preserve the coherence of story is a disservice to information.

Likewise, twisting information to maintain relevance to an audience is also a danger path to follow.

Left to its own devices, raw information will show that any attempt by humans to to turn it into a coherent and relevant story is an act of hubris and folly.

Information unfolds in its own time and its own way. Any resemblance of information to a particularly story is more likely to be a coincidence than any hard fast rule.

Managing information in order to maintain coherence and relevance over a period of time is actually doing a disservice to everyone over the long haul.

Information is fluid and evolves rapidly. While overreacting to new information is potentially dangerous, it is also risky to hold on to older outdated information for too long.

The hard part is knowing the difference. While information is being created and distributed at a rapid pace, the ability of individuals to process this information is much slower. The exploitation of this gap is where we get into trouble.

The coherency and relevancy of any bit of information depends on how well it fits into the story that the receiver of the information lives by.
