An economist was asked to talk to a group of business people.
She tacked up a big sheet of white paper. Then she drew a black spot on the paper and asked a man in the front row what he saw.
The man answered promptly, "A black spot."
The speaker asked every person in the room the same question and each replied, "A black spot."
With calm and deliberate emphasis, the speaker then said, "Yes, there is a little black spot, but none of you mentioned the big sheet of white paper. And that's my speech."
