The "Idiosyncratic rater bias" is a bit confusing to me, since it starts already with Bob being an EM, and to counter it is suggested to write from the manager's perspective. So what are managers supposed to do when they are falling for this bias like Bob did? Was either the example or the solution different initially? Maybe it's just the phrasing. (Hey, EM-Bob, try to write like a manager … — Erm, I am one. Duh.)
