The Four Lenses

Every topic gets worked from four sides. A question can start anywhere — sometimes the product need comes first, sometimes a paper does — but a note isn’t finished until all four have been asked.

Research

What is actually known, what is claimed, and what would falsify it? Papers, evidence, open problems.

Engineering

How is it built, what breaks at scale, and what does the implementation cost? Code and measurements.

Product

Who feels the difference, and how would they notice? The gap between a benchmark and a user.

Strategy

Where does the leverage sit — for a lab, for a company, for one person working alone?
