If someone says they rely on #2 pencils for writing memos to their boss and do not use #4 lead pencils because four is bad mojo and two is good mojo, they might be right in using a #2 pencil but for the wrong reason.
Number four lead is a hard lead and its trail is difficult to see. If this person evaluates the goodness of mojo experientially, their memos were undoubedly ignored when written with a #4 pencil and acted on, in some manner, when written with a #2 pencil. The reality is, I'd argue, that the boss couldn't read the former but could read the latter, no mojo involved.
Thus, right write for the wrong rite.
