Working Memory
How many open loops are draining your attention right now?
Your cognitive workspace. The small, volatile buffer where active thinking happens — roughly 4-7 chunks at once. Every context switch flushes the buffer. It takes 23 minutes to return to deep focus after an interruption. Context switching consumes up to 40% of productive time.
| Without Memory Management | With Memory Management |
|---|---|
| Constant mental juggling | Externalised, trusted system |
| Attention residue between tasks | Clean transitions |
| Shallow work by default | Deep work by design |
| "Where was I?" | "Here's where I left off" |
Your brain is for having ideas, not storing them.
Memory Architecture
The same patterns appear in human cognition and AI systems:
| Type | Human | AI Equivalent | How to Manage |
|---|---|---|---|
| Working | Active thought buffer (4-7 chunks) | Context window | Externalise — write it down |
| Episodic | Specific experiences and events | Conversation history, logs | Journal — capture while fresh |
| Procedural | Learned skills and habits | Fine-tuned behaviours, routines | Practice — repetition builds muscle memory |
| Semantic | General knowledge and facts | Training data, RAG retrieval | Reference systems — don't memorise what you can look up |
Memory sophistication is the differentiator. For both humans and agents, better memory management means better reasoning.
Externalisation Protocol
Get everything out of your head into a system you trust:
| What to Externalise | Where | Why |
|---|---|---|
| Tasks and commitments | Task manager (one system, not many) | Open loops drain working memory in the background |
| Meeting notes and decisions | Shared docs, immediately after | Memory degrades within hours |
| Ideas and insights | Capture tool (always accessible) | Inspiration decays fast |
| Project context | "Where I left off" notes | Eliminates 23-minute recovery cost |
| Reference material | Searchable knowledge base | Don't memorise what you can look up |
The test: do you trust your system enough to forget? If not, your brain is still holding the load.
Chunking Strategy
Working memory holds 4-7 chunks. Make each chunk bigger:
| Raw Information | Chunked |
|---|---|
| 0-4-1-5-9-2-6-5 | 04-15-92-65 (four chunks, not eight) |
| 12 unrelated tasks | 3 projects with 4 tasks each |
| Complex argument with 8 steps | 3 phases: setup, core, conclusion |
| New codebase with 50 files | 5 modules, each with a purpose |
Experts and novices have the same working memory size. Experts just have bigger chunks.
Context Protection
| Threat | Cost | Defence |
|---|---|---|
| Notifications | 23 minutes per interruption | Silent mode during deep work |
| Task switching | 40% productivity loss | Batch by type, theme your day |
| Open browser tabs | Continuous partial attention | Close everything not needed now |
| Meetings without breaks | Residue from previous context | 5-minute buffer between meetings |
| Unclear next action | Decision fatigue, procrastination | End each session by writing the next step |
Daily Protocol
- Morning — Review your system. Load today's context. Identify the one thing.
- Deep work — Peak energy hours. Single task. No inputs.
- Process — Clear inbox, respond, update system. Batch reactive work.
- Close — Write where you left off. Empty your capture tool. Close all loops you can.
- Rest — Trust your system. Let your brain recover.
The Shadow
Hoarding information. Refusing to externalise because "I should remember this." Over-optimising systems instead of doing the work. Mistaking organisation for output. Building the perfect system instead of shipping the imperfect thing.
By Archetype
| Archetype | Memory Style |
|---|---|
| Engineer | Holds systems in mind — builds from complexity with external scaffolding |
| Philosopher | Synthesises across domains — needs deep, uninterrupted context |
| Coach | Remembers people — context about individuals and relationships |
