Wyers: The mystery of the missing .500 teams

From SABR member Colin Wyers at Baseball Prospectus on June 28, 2013:

Sometimes, baseball research happens because you go out looking for something and you find it. Other times, it happens because you go off looking for something else and you trip over something far more interesting. This is the latter. While looking through historic team records for another project I was working on, I came across an interesting puzzle—there were far fewer teams exactly at .500 than I would have expected. I thought maybe it was a wacky feature of the sample set I was using, but I expanded my search to nearly 50 years of Major League Baseball, and the same puzzle was still staring me in the face. So I was left with three questions: Was what I was seeing really there? Why was it happening? And what did it mean?

One of the best parts of working at Baseball Prospectus is the ability to pester the staff email list with really bizarre questions. Some people use this power to ask questions where they don’t know the answer. Those people are probably much more well-liked than I am by the other staffers. I, instead, ask questions to which I already know the answer and request that people make wild guesses without doing any research first. I do this because sometimes when I’m looking at data, it helps me to get an unbiased perspective of what someone might expect the data to look like. But to get that, you need to ask people who haven’t seen the data, because once you’ve been staring at the data for too long you expect the data to look like the data.
