I light of that, I propose the following modified test:
Split the objects into different categories, for example:
Famous people, Soft drink brands, Colours, shapes, animals etc.
From each category, choose 10 or so different items which are:
- easily recognisable
- easily distinguishable
- easily obtainable
Post ALL choices onto the board. Categories would have to be approved by cityboy and glee. If possible, post an example of all objects used so there is no confusion.
AFTER this step is done, devise some random method of choosing one object from each step. I would prefer it to be software based and not merely heuristically random like the book flipping example. Tossing a coin or rolling a die would also be acceptable if you describe the algorithm beforehand. Once that is done, place the items chosen onto the table and await results. Some enterprising statistician could then post the confidence Interval for cityboy being a psychic.
As for cityboy, I am trying to make this as easy for you as possible while still setting up a decent amount of odds. It’s far easier to pick an object out of a group than to remeber the object afterwards. You can also say that you were uncertain about an object or say it could be X or Y but keep in mind that this will reduce the confidence interval.
As a suggested guide:
Categories:
Shapes & Colours (combined), stylised cartoon picture of an animal, Famous shot of a celebrity, religious symbol, sporting equipment, cartoon picture of musical instrument, Letter of the alphabet.
shapes:
- Square
- Circle
- Triangle
- Kite
- Trapezium
- Arrow
Colours:
- Red
- Green
- Blue
- Yellow
- Black
- Purple
Animal:
- Dog
- Cat
- Fish
- Cow
- Chicken
- Monkey
you get the point…
If you choose 8 categories and 6 options from each category, its an 1 in 1.6million chance of getting them all right from guessing yet I am thinking that it would be trivial if you were shown a photograph of them.
