M: Say that hypothetically, I managed to give you every piece of information you could possibly need for a question, and then ask you to analyze second, third, and fourth order likely affects. As you get higher in the number, what level of resource and or time use do things increase by? Is it linear, exponential, something even worse…?

G: Short answer: It’s not linear. The cost of analyzing second-, third-, and fourth-order effects tends to grow exponentially or worse, depending on:

  1. Branching factor (how many effects each cause has),
  2. Interdependencies (how effects feed back into or compound with each other),
  3. Stability of the system (chaotic or self-correcting),
  4. Scope of simulation or prediction.

Breakdown:

Order of Effect Description Resource Scaling Trend
1st Order Direct consequence Baseline
2nd Order Consequences of the consequence ~3–10× more complex
3rd Order Consequences of those consequences ~10–100× more complex
4th Order+ Deep network ripple effects Explosive or intractable

Why It Gets Worse:


Summary:

So: scaling is exponential or worse, unless assumptions allow you to collapse branches.
