How to apply the seven lenses to anything — plus a Bayesian forecasting sketch.

The seven lenses

LensQuestion
What ExistsWhat is this, really?
What ChangesWhat is stationary vs non-stationary?
What FlowsWhat moves? Where are bottlenecks?
What LearnsWhat updates, remembers, optimizes?
What PersistsWhat survives change?
What EmergesHow do simple rules → complexity?
What Will HappenWhich futures are becoming likely?

Walk them in order the first time. Later, jump to the lens that matches your confusion.

Universal case study template

  1. TL;DR — three bullets
  2. Phenomenon — one-sentence definition
  3. Seven lens blocks — collapsible sections, same order every time
  4. Curriculum bridge — links to mechanism topics
  5. Forecasting snapshot — optional under What Will Happen

Forecasting walkthrough (Bayesian sketch)

Start with a prior — what you believed before today’s evidence.

Add likelihoods — how probable is this evidence if each future were true?

Compute posterior — where probability mass moves after observing reality.

Repeat — forecasting is a loop, not a ceremony.

The What Will Happen lens page includes an interactive Bayesian updater lab.
