How to Build a Deck From One Nonfiction Book

One dense nonfiction book is more than enough to make a terrible Anki deck.

It is also more than enough to make a brilliant one.

The difference between the two is never the book itself. The difference is purely based on what you think the deck is supposed to preserve.

Nonfiction creates two totally different vocabularies

As you read through a smart nonfiction book (like Malcolm Gladwell or Daniel Kahneman), you will collide with two types of language:

1. Local Terminology: Tied entirely to this book's specific subject matter.
2. Reusable Conceptual Language: Structural phrasing that will definitely show up in other books later.

The first category feels incredibly important right now because it helps you survive the current chapter. The second category is exponentially more valuable long-term because it helps you survive every other book you will ever read.

Build around recurrence, not panic

The strongest vocabulary candidates are almost never the fanciest ones. They are the items that:

• Recur across three different chapters.
• Carry the author's explanation or analysis.
• Show you exactly how the author reasons through a problem.

You must build late, not continuously.

Do not stop reading to make a flashcard. Mark candidates lightly with a pen or a digital highlight. Only build the actual cards after three or four chapters have passed. By then, the book's true recurring language will be incredibly obvious.

If chapter after chapter keeps returning to terms like constraint, incentive, distribution, gradual, assumption, or outcome, you have found the engine. The book is teaching you a reasoning language, not just a topic.

Extract the engine. Ignore the paint.
