Occasionally I see a comic that has a grocery store checkout that says “fewer.” Here’s another one. The digression is below the comic.
Okay, digression. This is about the likelihood of picking the fastest line and why we always seem to not pick it. The reason is that line speeds are actually random, and when we pick a line, we compare where we are to the line on each side. That makes the odds of picking the fastest line three to one. So sometimes we do pick the fastest line, but only one out of three times feels worse than it is. I read this in an article in Scientific American, so it must be true.
