Think of it this way: Your professor asks you for the name of the imaginary friend that the professor's son always talks about. You have no idea what the answer could possibly be, so in your head you choose "John," a reasonably common name with a very low probability of being right. Google answers with a strong conviction in it's voice that the answer is "Mark," another common name. You have no evidence to believe that your own guess is correct, so in the face of the appearance of belief on Google's behalf, aren't you the least bit tempted to say that it's Mark and not John?
