Now i explain Johnstone’s algorithm .
"I say to an actress, ‘Make up a story.’
She looks desperate, and says, ‘I can’t think of one.’‘Any story,’ I say. ‘Make up a silly one.’ ‘I can’t,’ she despairs.
‘Suppose I think of one and you guess what it is.’
At once she relaxes, and it’s obvious how very tense she was.
‘I’ve thought of one,’ I say, ‘but I’ll only answer “Yes,” “No,” or “Maybe.”’
She likes this idea and agrees, having no idea that I’m planning to say ‘Yes’ to any question that ends in a vowel, ‘No’ to any question that ends in a consonant, and ‘Maybe’ to any question that ends with the letter ‘Y’.
For example, should she ask me ‘Is it about a horse?’ I’ll answer ‘Yes’ since ‘horse’ ends in an ‘E.’
‘Does the horse have a bad leg?’
‘No.’
‘Does it run away?’
‘Maybe’
She can now invent a story easily, but she doesn’t feel obliged to be ‘creative,’ or ‘sensitive’ or whatever, because she believes the story is my invention. She no longer feels wary, and open to hostile criticism, as of course we all are in this culture whenever we do anything spontaneously.”

what number you say yes or no??
