The Change recommended in Exhibit 5.1 is much harder to strip using the “If I do X, then there’s a Y percent chance that Z will happen” formula, and that’s informative. X is hard to pin down, and Y is unspecified. To be fair, this advice was drawn from a blog entry, so perhaps I shouldn’t take it all that seriously. At the same time, though, you see a lot of advice to teachers that is similarly frothy. Such advice is difficult to disagree with, but it doesn’t help because it is so indefinite.
