There is a certain type of person often encountered in public forums on the Internet but also in “real life.” I call this kind of person, the “drive-by Yoda”.
He is a “Yoda” because like Yoda, he likes to speak words of wisdom. However, his method is to spout wisdom while driving by his target. In a drive-by shooting, a criminal tries to kill a target by shooting bullets out of a moving car. In a similar way, the drive-by Yoda tries to make a point (i.e. hit a target) by spouting wisdom while “driving by” a discussion. I’m talking here about discussions in which all the parameters of a problem have been explained. The drive-by Yoda, because he is driving by at a fast pace, is unable to seize the whole picture. It may be that he is lazy, that he can’t be bothered to really think about the problem, or that he thinks the problem is not worthy of his attention. At any rate, he whizzes by but rather than apply a healthy dose of self-awareness to realize that maybe he does not have the full picture and therefore should remain quiet, he still offers pearls of wisdom. Yet because the drive-by Yoda has not seized the problem, his contribution is faulty. He fills the gaps in his understanding of the problem with wild guesses and offers an answer which is patently inadequate to anybody who paid attention to the parameters of the problem.
It is a bit like in the American Idol auditions at the start of a season. Very many contestants who could not sing a tune to save their lives consider themselves to be great singers. The drive-by Yoda thinks his contribution is worthy of a prize when in fact it ignores the problem being discussed.
