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.

Your brain is for having ideas, not storing them.

Memory Architecture

The same patterns appear in human cognition and AI systems:

TypeHumanAI EquivalentHow to Manage
WorkingActive thought buffer (4-7 chunks)Context windowExternalise — write it down
EpisodicSpecific experiences and eventsConversation history, logsJournal — capture while fresh
ProceduralLearned skills and habitsFine-tuned behaviours, routinesPractice — repetition builds muscle memory
SemanticGeneral knowledge and factsTraining data, RAG retrievalReference 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 ExternaliseWhereWhy
Tasks and commitmentsTask manager (one system, not many)Open loops drain working memory in the background
Meeting notes and decisionsShared docs, immediately afterMemory degrades within hours
Ideas and insightsCapture tool (always accessible)Inspiration decays fast
Project context"Where I left off" notesEliminates 23-minute recovery cost
Reference materialSearchable knowledge baseDon'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 InformationChunked
0-4-1-5-9-2-6-504-15-92-65 (four chunks, not eight)
12 unrelated tasks3 projects with 4 tasks each
Complex argument with 8 steps3 phases: setup, core, conclusion
New codebase with 50 files5 modules, each with a purpose

Experts and novices have the same working memory size. Experts just have bigger chunks.

Daily Protocol

  1. Morning — Review your system. Load today's context. Identify the one thing.
  2. Deep work — Peak energy hours. Single task. No inputs.
  3. Process — Clear inbox, respond, update system. Batch reactive work.
  4. Close — Write where you left off. Empty your capture tool. Close all loops you can.
  5. 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.
