The Method · Step 3
The Concept Anchor
An isolated fact decays in days. A fact anchored to a mechanism decays in months. The Concept Anchor is the one-sentence why behind every fact you log.
The Rule
You may not log a fact without writing one sentence of mechanism beside it. Not the fact again in different words — the reason the fact is true.
| Fact (forgettable) | Anchor (durable) |
|---|---|
| Verapamil causes constipation. | Verapamil blocks L-type Ca²⁺ channels in gut smooth muscle, reducing peristalsis. |
| Sheehan syndrome causes failure to lactate. | Postpartum pituitary infarction destroys lactotrophs first because they are most metabolically active. |
| Aortic stenosis murmur softens with Valsalva. | Valsalva drops preload → less blood across stenotic valve → quieter murmur. (HOCM does the opposite.) |
Why Anchors Work
Memory research consistently shows that elaborative encoding — connecting new information to existing knowledge — produces dramatically better long-term retention than rote rehearsal. The Concept Anchor is elaborative encoding in its simplest form: one sentence linking the new fact to a mechanism you already know.
If you can't write the anchor
You don't know the fact yet. Look it up before you log it.Anchors That Don't Count
- Restating the fact in different words.
- Naming the disease without explaining the physiology.
- "Because it's high yield." (We are not joking. Students write this.)
