Netmeg, I'm not trying to sell google traffic shaping. Logically the answer is probably a combo of number 2 through 4.
However, if anyone can measure probability it's google. They *can* know what you search is, transaction-al, navigational, or informational. They *can* know which link you are prone to click on.
