Once the poll is made, the answers cannot be edited. The difference was supposed to mean approximately a) I don't believe this could ever happen, b) I believe it can happen exceptionally, but not all the time as the author claims, c) I believe this can be the way system works.
In other words, the second option is like: "I believe that with so many grant proposals, once in a while a crazy thing passes unnoticed; but I don't believe that it happens all the time, not even half of the time -- you have probably seen one or two bad cases, and now you exaggerate to make your case more appealing".
So, you are asking me to condition on belief that the author of this post isn't a troll who crafted this story in such a way to be especially appealing to the LW community. Am I right? If I am, you probably should edit your original post to make your idea more clear.
