Reasoning

Cognitive Debt

The accumulated cost of repeatedly skipping the effort that maintains a circuit.

How it feels

Each shortcut feels harmless. Then the unassisted version of the task starts feeling strangely heavy.

At work

A team gets faster at AI-generated planning docs while becoming worse at debating plans without the doc.

Hidden cost

Reasoning: avoided effort compounds into weaker independent performance.

You may have this if

Name one cognitive task that has become harder since AI entered your workflow.

Try this instead

Create a weekly no-AI maintenance rep for that task: write, recall, decide, or synthesize before tool use.

Team rule

Every AI-accelerated workflow needs one preserved human maintenance rep.
