The main reason I posted this is that I am sometimes wrong about things. Maybe the zebra example turns out to make sense in some way I hadn't thought of. Maybe Yagami is using some sort of standard method. Maybe there's some failure mode I haven't thought of. It would be really good to know this before I make an ass of myself with the review. And talking about asses - there are some wild asses in Mongolia which got left out of my parable - but they're kind of cute so here is a link.
The problem is that as Protagoras brought up above, there may be issues that you are missing. It doesn't really make sense to consider the failure mode that you missed the importance of some detail, but not consider the failure mode where you missed not only the importance of the detail, but the detail itself.
