Last week, the lectures at Chautauqua focused on the Supreme Court. The roster of speakers included Linda Greenhouse, Annette Gordon-Reed, Jeffrey Rosen, Akhil Reed Amar, and Theodore B. Olson. You can see some of the talks here.
With all the talk of the Bill of Rights, it occurred to me that someone must have come up with a good mnemonic for them. But I have been disappointed by most of what I have found. Here is one of the better ones:
If you know of one that you like, please let me know.
There is a well developed literature of mnemonics for the medical profession. I am surprised that I am unable to find a similar body of work for the law.
From square of b, take 4ac;
Square root extract, and b subtract;
Divide by 2a; you’ve x, hooray!
I am not sure of the origins of this mnemonic. The earliest version I could find was from J. S. Mackay in 1894, but he says the mnemonic was given to him by a member of the Edinburgh Mathematical Society.
Here’s another mnemonic for the quadratic formula:
In the peg method, sometimes called the minor peg system, an individual memorizes a fixed set of ordered mnemonic cues. It can be used to learn ordered and unordered lists, such as a set of historical events or your weekly shopping. The technique relies on the use of vivid visual images.
The most widely used peg system is the number peg method. This system invented by John Sambrook in 1889 and a simplified version is described in most books on memory improvement. The peg word system is easy to learn and can supplement other mnemonic devices that we will be learning, such as the Dominic system. The first step is to create a numbered list of ten mnemonics pegs. Each peg word should rhymes with its respective number making the list easier to learn. Here is a suggested list, but you should modify if you can think of words that are more memorable to you. For example if the word “bricks” is easier for you to visualize than the word “sticks,” by all means, use it as your peg word for number six.
Number Peg Word
1 Gun
2 Shoe
3 Tree
4 Door
5 Hive
6 Sticks
7 Heaven
8 Gate
9 Vine
10 Hen
Once you have committed the list to memory, you are now ready to try to learn a list. What you will do is to make a vivid visual association with each item.
So let’s try to learn a grocery list. Suppose you want to purchase the following ten items; 1. oatmeal, 2. apples, 3. bananas, 4. spaghetti, 5. peanut butter, 6. carrots, 7. mushrooms, 8. maple syrup, 9. baked beans, 10. soy milk. Here is a chart suggesting visual associations between the items and the peg words.
Number
Peg Word
Item
Association
1
Gun

2
Shoe
Apples

3
Tree
Bananas

4
Door
Spaghetti

5
Hive
peanut butter

6
Sticks
Carrots

7
Heaven
Mushrooms

8
Gate
Maple syrup

9
Vine
Baked Beans
Cans of baked beans growing on a vine
10
Hen
Soy milk

If some of these associations seem bizarre, so much the better. The more bizarre, the easier to remember, a phenomenon called the bizarreness effect. It is important to try to create vivid visual images for each association. If, in addition you can link the image to something you already know the easier it will be to remember. For example, when I think of a gate holding back a flood of maple syrup, I am reminded of the Boston Molasses Disaster of 1919
When one reuses the same pegs over and over again there is always some danger that memorizing one list might interfere with the learning of a later list. However, research suggests that the number peg system can used over and over again.
Here is a video showing a version of the number peg system:
In this video, memory athlete Nelson Dellis demonstrates the link method of list learning. The method depends upon making bizarre mental images and linking the items on the list together in a sequential story.
