Why can’t I layer two deductive storylines on top of each other?

Layering deductive storylines is both logically risky and awful for your reader

  1. It's logically risky. Given that the ideas within a deductive storyline are inextricably linked to each other, if one fails, so does the whole story. If you construct your story using layer upon layer of deductive chains, you are constructing a logically fragile structure. For example, if one idea or one link in the bottom generation is flawed, then this flaw feeds up to the highest level, and brings the whole story undone.
  2. It's awful for your reader. Drawing your audience through a stream of deductive generations one after another to get to your main point is no fun for them. It is very difficult to follow the logic and grasp the key ideas from stories constructed this way.
