Measure for Mismeasure

We live in a world where everything is being rated, whether you are a professional judge or an individual trying to make sense of modern life. And yet ranking exercises, like the things they rank, are not all the same; different approaches fit different situations.

ISTANBUL – I recently used Uber (an online service for ordering a car and driver) and did not have the usual pleasant experience. The driver did not know the area, and, worse, he did not follow his navigator’s instructions, turning left instead of right. When Uber asked me, as usual, to rate the driver, I did not hesitate to give him two out of five. I was not being vindictive; I wanted to save other passengers from an unpleasant experience, and I hoped that maybe feedback would encourage him to improve or find another line of work.
