Unlimited Memory

Memory is a skill

Unlimited Memory by Kevin Horsley came out in 2014. Its subtitle is How to Use Advanced Learning Strategies to Learn Faster, Remember More and Be More Productive. It is a short, practical book that teaches the classic techniques of memory athletes in plain language, with exercises along the way.

Horsley is a South African speaker and memory trainer. He describes himself as a poor student as a child. He says he had dyslexia and found traditional learning hard, and teachers treated him as a slow learner. After school he set out to study how memory works and how people with strong memories use it. He began to practice the techniques himself. He later competed at the World Memory Championships and holds the title International Grandmaster of Memory. He also set a world record in a pi test known as the Everest of memory tests. The examiners read out a five-digit block from the first 10,000 digits of pi, and he names the five digits on each side of it, 50 times in a row.

His starting claim is that there is no such thing as a bad memory, only a trained or an untrained one. Memory is not a fixed talent. It is a set of skills that anyone can learn, and the techniques work for people of any age. A better memory, he argues, does not only help with exams. It supports confidence, creativity and productivity, because so much of thinking depends on what we can recall.

Start with the mindset

Before the techniques, Horsley deals with the reasons people do not improve. Most people carry beliefs such as I am too old, I have a terrible memory for names or I am not smart enough. He argues that these beliefs become self-fulfilling. If you are sure you will forget, you do not pay attention, and so you do forget.

He asks the reader to drop the excuses and list their reasons for wanting a better memory. Strong reasons supply the motivation to practice. He also argues that memory is closely linked to interest. People remember what they care about. If you can find a reason to care about the information in front of you, you will pay more attention, and attention is the first step of memory.

Concentration

The second foundation is concentration. Horsley argues that most forgetting is not forgetting at all. The information never went in, because we were not paying attention when it arrived. A name you forget ten seconds after an introduction was never stored, because you were thinking about what to say next.

He treats concentration as a skill too. The main enemy is the inner voice, the running commentary that pulls attention into worries, plans and judgments. Horsley suggests ways to quiet it: set a clear purpose before you read or listen, remove distractions from your space, work in focused blocks and notice when your mind drifts so you can bring it back. He argues that improving concentration is as much about stopping bad habits, such as constant multitasking and checking devices, as it is about starting good ones.

Turn information into pictures: the SEE principle

The heart of the book is the idea that the brain remembers images far better than words or numbers. Abstract information slides away. A vivid picture sticks. So the core technique is to convert what you want to remember into images.

Horsley's rule for making images memorable is the SEE principle:

• Senses. Use all five senses. Do not just see the image. Hear it, smell it, feel it and taste it.
• Exaggeration. Make the image huge, tiny, absurd or funny. The brain notices what is unusual and ignores what is ordinary.
• Energize. Add movement, action and color. A still picture is weaker than one where things crash, explode or dance.

An example shows the difference. To remember to buy batteries, a plain image of a battery pack on a shelf will fade by the afternoon. A giant battery that rolls down your street, fizzing and crackling with sparks, smelling of burnt plastic and crushing parked cars, is hard to forget. The second image takes a few seconds longer to make. Horsley's point is that those seconds are the real act of memorizing. The effort of building a strange, detailed picture is what forces attention onto the information.

For abstract words, he uses substitution. You turn a word you cannot picture into one that sounds similar and can be pictured. Washington becomes someone washing a ton of laundry. Athens becomes eight hens. Brussels becomes a pile of Brussels sprouts. The image does not need to be accurate. It only needs to bring the word back.

Connect new information to what you already know

Images alone are not enough. You need a way to store them in order and find them again. Horsley's solution is to attach new images to structures already fixed in your memory. He expresses the idea as a simple formula: long-term memory plus short-term memory gives a stronger medium-term memory. You use something you already know well as a set of hooks.

He teaches several such structures:

• The body method. You choose ten places on your body, from your feet up to the top of your head, and attach one item to each. Horsley uses it to memorize a list of ten types of intelligence.
• The car method. You choose a fixed set of places in your car, moving in a set order from the front of the car to the back, and attach one item to each. He uses it to store a list of healthy foods and the seven habits from Stephen Covey's book.
• Location and route methods. You walk a familiar route, such as through your house or along a street, and place an image at each stop. This is the method of loci, also called the memory palace, used since ancient Greece.
• Rhyme and shape pegs. You link numbers to images that rhyme with them or look like them, such as a pencil for one or a swan for two, and attach items to those.

To recall the list, you walk through the structure in your mind and read off the images. Because the order of the structure is fixed, the order of the list comes back too.

Applying the systems

The rest of the core section shows how far the systems can stretch. Horsley demonstrates layering: once you have stored a list, you can add more images to each item. For example, after you store a list of names in order, you can add dates and key facts to the same images.

He applies the methods to practical tasks:

• Names and faces. Pay attention at the moment of introduction, repeat the name, turn it into an image and attach that image to a striking feature of the person's face.
• Numbers. Use a code that turns digits into images, so a string of numbers becomes a short story. Memory athletes use codes like this to memorize long strings such as the digits of pi.
• Speeches and presentations. Store each main point at a stop on a route, so you can speak without notes.
• Reading and study. Pull the key ideas out of a text and turn them into images placed on a structure.
• Daily tasks and to-do lists. Place each errand on a body or car location.
• Playing cards. Memory athletes use the same principles to memorize a shuffled deck.

Continuous use and review

The last foundation is practice and review. Horsley argues that techniques only work if you use them every day until they become habits. Self-discipline matters more than talent, and he urges readers not to let mood decide whether they practice.

He also explains the forgetting curve. Without review, most new information fades within days. His solution is spaced review: go over the material at growing intervals, for example after ten minutes, an hour, a day, a few days, a week and then several weeks. Each review takes less time, and the memory becomes more stable.

He presents the techniques and the reviews as partners. A vivid image on a strong structure makes the first storage easy. Review keeps the path to it open. Without the images, review is slow rote repetition. Without review, even good images fade. Used together, they let a person build up large bodies of knowledge over months, which is what he means by an unlimited memory.

What the critics say

Reviewers generally find the techniques sound but familiar. The SEE principle, the memory palace and peg lists are classic mnemonic methods described in many other books, and Horsley adds little new science. Some readers find the motivational sections heavy and the title overstated, since mnemonics help most with lists, names and numbers and less with deep understanding of complex ideas. Other readers find it a clear short introduction for beginners.

Who should read it

Read it if you want a quick, practical start on memory techniques for names, lists, numbers, speeches or study. It is short enough to read in an evening, but the value comes from doing the exercises.
