10000 people memory system

Here are 2 ideas for making a 10,000 person system. The first is the more complex and will likely never happen because I would need collaboration to build it...


Many Mnemonics are built on visual imagery. Imagining people can be useful because a story can be imagined where that person does an action to an object or person and thus the visualised story grows; that story can represent data such as the digits of numbers or points for an essay plan. In short, people are good for mnemonics.

I have a plan for building a system of 10,000 people. So, if someone asked, "Who is person 8347?" then I should be able to provide the answer. This is done by representing 8347 as 83;47 where the 83 is going to give me a first name and the 47 is going to give me a surname. The following tables make this idea clearer:


This table concerns first names:

'Hair Long' for a man is hair below the ears or hair which is several centimetres in length and perhaps unkempt.

'Hair Long' for a woman is hair at or below the shoulders (and so not hair in a bun shape).

First name 83 is Ruth. Surname 47 is Shane. So the person is Ruth Shane.

83, as a first name, is a female who is of ethnicity Oriental. So, the 83 tells me what the person vaguely looks like.

The ethnicities are vague as well. If someone is dark-skinned and could come from the Middle East then I might group that person in the same category as 'Indian'; because 'Indian' is just a short word to emphasise that the person is not a dark African or a European white person or an oriental person. It is always a rough approximate term and never meant to be precise.

I just want to speedily categorise the photos which I will encounter so that this system becomes a reality.

Another theme is to not disguise faces much. eg. Sunglasses obscure face detail and I would steer away from that sort of generalisation of a face.


These are the 5 'ethnicity' types:

European (black or dark brown hair).

European type 2 (NOT black hair and NOT dark brown hair).

Oriental (from countries like China or Thailand).

Indian or dark Middle Eastern.

African (from countries like Nigeria or DRC).


The surname is Shane and the features and age of a person with that surname are: 'Middle Aged and Hair Long' - you can see this in the table above.

So a name suggests how someone should look. What is then required is a way to find a photograph or image of a person who fits that loose description.


Since it is not based on the English language, this system should be easy to teach to anyone in the world.


Photofit effect

My aim is to use public domain images as inspiration for visualising faces. There is no point in me struggling to mentally recall an unmemorable face. I want to learn a photofit generalised version of the faces which I am going to use. If that photofit was shown on a crime reconstruction tv show then I would expect it to match a lot of face profiles. I do not know the correct term for this generalised face - a 'face type' perhaps. And if I showed that image to the person who inspired it then they might categorically protest that it looks nothing like them. And, if the public domain image was no longer online, I could perhaps find a similar type of face and use that as a rough model of the 'face type'.

Clothing and mathematics

Like with the 100 math people, the clothing of the people may be a code for some mathematical result. eg. 8347 might be a person whose clothes give part of the anser to '83 divided by 47' .


Simpler 10000 People System

There is a lot of interest, in the memory hobbyist community, in memorising playing cards.

One way of doing well at memorising cards is to use one visual image to represent 2 cards.

So, for motivation's sake, a 10,000 system of people would not necessarily be built by presenting image 0001, 0002, 0003, onwards but by learning the ones which would be a useful cross-section of a 10,000 system.

I believe that a 2-cards-to-1-image system of interest would be one where the image for, say, 9 of Hearts, 3 of Clubs is based on representing most of that data in a 52 x 26 system where the 9 of Hearts is memorised along with the fact that card 2 is a black '3 numeral' card. It would be the next aspect of the visual memorisation story which clarifies the identity of that card - if that is desired. The system is small enough to keep someone motivated to learn it; and could lead later to the undertaking of a 52 x 52 system of card pairs.

As for the people and their numbering, I am planning to strip the names from the people; the reason for choosing celebrities is principally because I could publish a list of celebrities and interested readers could easily find a library of images for those people by using a search engine.

I have a list of 100 celebrities already in my 'Numbers in Images' article.

Person 01 is Adam Sandler. Person 00 is Will Smith.

It seems like an organised idea to me that people 0000 to 0099 might be male people with dark skin and dark hair like some would describe Will Smith. People 0100 to 0199 might be male people with lighter skin because Adam Sandler might be said by people to tend towards a light skin colour.

In fact, I might have to modify my original 100 celebrity article if I find that I have spare 100 images of oriental male people and no celebrity left who is oriental for them to be associated with.

However, I would give each person in the system a brief alias built from the following idea:

each 2-digit number from 00 to 99 has a matching syllable. eg. BA = 05 and AL = 02 .

If I give someone the nickname BAAL then that person is person 0502 (BA.. = 05, ..AL = 02 ) .

Once the system is big enough to achieve a purpose such as memorising cards, I can 'broaden my horizons' and use public domain images of people in general to represent other values in the 10000 people system.

I should present the caveat that it is sometimes contentious to categorise someone as belonging to a category based on how they are perceived to look; and my categorisation method is rough and a just a mechanism for better recalling photos of people in association with their sequence number.
