Most of your experience at work is mediated through the lie that people can reliably rate other people. How you are selected, how you are promoted, how you are paid, how you are developed, and possibly how you are terminated – these all depend on somebody else’s rating of you.
And while you certainly want to have a high rating, at the very least you should expect to have an accurate one.
But unfortunately, that’s not true. People are not reliable raters of other people – and we’ve known this for decades. The main reason is called the “idiosyncratic rater effect,” and it works like this: when I rate you, over 60% of your rating is about me, and not you. Which is a big problem, because we are paying, promoting, training, and deploying you based on that rating — which doesn’t reflect you. So ratings are a terrible performance measurement tool, because they claim to measure one thing but actually measure another.
Now many people think that by combining my rating of you with several (or many) other people’s ratings of you will somehow reveal the truth – but that’s also wrong. Just like noise plus noise will never equal a signal, bad data plus bad data will only ever equal more bad data.
We are not reliable raters of other people, and we harm people – both the individuals on our team as well as all the people in our companies –when we assume that we can rate them reliably.
