The three stages of science

Not a real poster - parody for entertainment purposes only. Did I really need to say this?

There is a saying that all new ideas in science pass through three stage.

At first they are ignored
Then they are vigorously attacked and ridiculed.
Finally everyone says they believed them all along and they are ridiculed again - this time for being obvious.

Seeing John Snow's work in the Daily Show's 'Earth - a visitor's guide to the human race' reminded me of this.
