INTRODUCTION

CORE DEFINITION

A principle of study holding that quality and depth matter more than the number of topics covered, so a short list studied thoroughly beats a long list skimmed. The model treats focus as the scarce resource in an age of abundant information. The qualification is that depth in one field still needs enough breadth to see how the field connects to others, so the principle opposes scattering rather than all breadth.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use List Pruning: cut the study list to the few items you will genuinely finish. - Use Depth Standard: ask how its underlying principles work rather than what it says.

anchor

Anchor fast decisions

Deep study builds structured schemas that transfer to related problems, while broad skimming leaves isolated facts that decay. Because attention is limited, spreading it across many topics keeps every schema below the threshold where it becomes usable, so fewer topics pursued further yield more capability.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

List everything that you currently intend to study. 2. Cut the list to the few you will finish. 3. For each, ask how its underlying principles work. 4. Apply each one in a real project rather than in theory. 5. Resist adding new topics until the current one is consolidated.
