What is graph building blocks?

Graph building blocks is a concept in personal epistemology: Concepts are nodes and relationships are edges — together they form a graph.

Example: You write three notes in your notebook: "cognitive load," "working memory," and "chunking." Three isolated facts. Then you draw a line from "cognitive load" to "working memory" and label it "is constrained by." You draw another line from "chunking" to "working memory" and label it "expands capacity of." Suddenly you do not have three facts. You have a structure. You can see that chunking is valuable because it addresses a constraint on working memory, which is where cognitive load becomes a problem. The notes did not change. The connections between them created understanding that the notes alone could not.

This concept is part of Phase 18 (Knowledge Graphs) in the How to Think curriculum, which builds the epistemic infrastructure for knowledge graphs.
