SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Dependency management. When you feel growth stagnating, check whether you are trying to skip prerequisite technologies (e.g., trying to understand large models without learning linear algebra). Draw your skill tree and fill in missing prerequisite nodes.

anchor

Anchor fast decisions

Skills or technologies exhibit hierarchical dependencies: higher-level abilities require foundational abilities as prerequisites; without unlocking prerequisite nodes, subsequent ones cannot be unlocked. Growth stagnation often results from attempting to skip prerequisite dependencies.

MINIMUM ACTION

In progress 0/2

Practice this model in one real situation:

Step 1: Draw the dependency tree (skill tree) for the target domain. Step 2: Identify the current node and missing prerequisite nodes. Step 3: Fill in prerequisites before advancing
do not skip levels. Step 4: Periodically review and prune irrelevant branches to stay focused.
