Memory is not a fixed cognitive trait. It is responsive to how you use it, how you sleep, how you structure your learning, and how consistently you engage in the habits that support effective encoding and recall. The most effective memory improvement strategies are not supplements or brain-training apps — they are specific behavioural habits backed by decades of cognitive research.
As Forbes’s summary of evidence-based memory enhancement strategies highlights, the gap between people with strong working memory and those with poor recall is less often a matter of biological capacity and more often a matter of technique and habit architecture.
Technique 1: Spaced Repetition
Spaced repetition is the most evidence-supported learning technique available. Instead of reviewing information in a single massed practice session, you space reviews across increasing intervals — reviewing information just before you would naturally forget it, which strengthens the memory trace with each review.
The science: memories are encoding as neural pathways. Forbes’s evidence-based breakdown of brain performance habits Each review strengthens and deepens those pathways. Reviewing too frequently (within hours of encoding) provides minimal additional strengthening. Reviewing at the optimal spacing interval — just as the memory begins to fade — produces the maximum strengthening effect.
How to Implement Spaced Repetition
- Anki — the gold standard spaced repetition flashcard app. Free, cross-platform, algorithm-optimised review scheduling. Ideal for language learning, technical knowledge, and any information requiring reliable long-term recall
- Readwise — automatically resurfaces highlights and notes from books, articles, and Kindle at spaced intervals. Excellent for professionals who read a lot and want to retain more of what they read
- Notion spaced repetition template — manual version: create a flashcard database with a “next review date” field, updating it after each review based on recall difficulty
Technique 2: Active Recall
The most common study mistake is re-reading. Re-reading feels productive because the information looks familiar — but familiarity is not the same as recall. Active recall — testing yourself on information rather than passively reviewing it — produces dramatically stronger memory traces.
How to Use Active Recall in Professional Learning
- After reading an article or chapter, close it and write down everything you remember — no looking back
- Review meetings or presentations immediately afterwards: write down the key points without looking at notes
- Use the Cornell Notes format: main notes on the right, self-test questions on the left. Cover the notes and answer the questions to test recall
- In Notion, create a “review page” for each book or course you complete: 5–10 questions whose answers require you to actually think and recall, not just locate
Technique 3: The Feynman Technique (Teach It to Learn It)
Named after physicist Richard Feynman, this technique is simple: explain what you are learning in plain language, as if teaching it to someone with no background in the subject. Where your explanation becomes vague or uncertain, you have identified the gaps in your own understanding.
- After learning a new concept, write a plain-language explanation in your own words in your notebook or Notion
- Identify where you used technical terms because you did not actually know how to explain the concept simply — those are your gaps
- Return to the source material to fill the gaps, then re-explain
Technique 4: Sleep as Memory Consolidation
Memory consolidation — the process by which new information is moved from short-term to long-term storage — occurs primarily during sleep, specifically during slow-wave and REM sleep stages. Reducing sleep duration or quality does not just make you tired; it actively impairs the brain’s ability to retain the information encoded during the preceding day.
Practical implication: learning something important and then sleeping poorly on it is functionally similar to not learning it at all. Protecting sleep quality is a memory strategy, not just a wellness habit.
Technique 5: Physical Exercise as Cognitive Enhancement
Aerobic exercise increases production of brain-derived neurotrophic factor (BDNF) — often described as “fertiliser for the brain” — which supports the growth of new neural connections and enhances the brain’s plasticity and encoding capacity. The research is consistent: regular moderate aerobic exercise improves both working memory capacity and long-term memory formation.
A 20-minute walk before a learning session or focus block provides measurable cognitive priming. This is not supplementation — it is neuroscience applied to scheduling.
A Daily Memory-Optimising Routine
- Morning: 10-minute walk (BDNF production) + review Anki deck or Readwise highlights (5–10 minutes)
- During work: capture key insights from meetings and reading in real time using Cornell Notes
- Evening: 5-minute free recall of the day’s most important learnings — write it out without reference to notes
- Before bed: protect sleep (no screens 1 hour before) to maximise overnight consolidation
Memory is trainable. The techniques above do not require exceptional intelligence or extraordinary effort — they require consistent application of what decades of cognitive research has established as effective. The gap between forgetting most of what you learn and retaining most of what you learn is almost entirely a matter of method.
