The company has compiled a list of “cognitive biases” for employees to keep handy during these discussions. For example, somebody may have just had a bad experience with the person being reviewed, and that one experience inevitably trumps recollections of all the good work that person has done in recent months. There’s also the “halo/horns” effect, in which a single personality trait skews someone’s perception of a colleague’s performance. //<br />
For now, Mr. Bock says he is particularly struck by the simplicity of the rules, and the fact that applying them doesn’t require a personality transplant for a manager.<br />

“You don’t actually need to change who the person is,” he says. “What it means is, if I’m a manager and I want to get better, and I want more out of my people and I want them to be happier, two of the most important things I can do is just make sure I have some time for them and to be consistent. And that’s more important than doing the rest of the stuff.”
