status bias in baseball umpiring

with 7 comments

Jerry Kim and I have an op-ed in Sunday’s New York Times about our new paper on status bias in baseball umpiring. We analyzed over 700,000 non-swinging pitches from the 2008-09 season and found that umpires made numerous types of mistakes in calling strikes-balls. Most notably, we expected that umpires would be influenced by the status and reputation of the pitcher, and this is indeed what we found:

One of the sources of bias we identified was that umpires tended to favor All-Star pitchers. An umpire was about 16 percent more likely to erroneously call a pitch outside the zone a strike for a five-time All-Star than for a pitcher who had never appeared in an All-Star Game. An umpire was about 9 percent less likely to mistakenly call a real strike a ball for a five-time All-Star. The strike zone did actually seem to get bigger for All-Star pitchers and it tended to shrink for non-All-Stars.

An umpire’s bias toward All-Star pitchers was even stronger when the pitcher had a reputation for precise control, as measured by the career percentage of batters walked. We found that pitchers with a track record of not walking batters — like Greg Maddux — were much more likely to benefit from their All-Star status than similarly decorated but “wilder” pitchers like Randy Johnson.

Baseball insiders have long suspected what our research confirms: that umpires tend to make errors in ways that favor players who have established themselves at the top of the game’s status hierarchy. But our findings are also suggestive of the way that people in any sort of evaluative role — not just umpires — are unconsciously biased by simple “status characteristics.” Even constant monitoring and incentives can fail to train such biases out of us.

You can can download the paper, which is forthcoming in Management Science, if you’re interested in learning more about the analyses and their implications for theories about status characteristics and the Matthew Effect.

when fighting is normal

Russ Roberts interviews political scientist Mike Munger on the topic of rules and institutions, using sports as an example. One of the most interesting things about sports is that there are informal rules governing fighting. A few key ideas:

  • To decrease overall fighting, you allow a little bit. It acts as a deterrent.
  • In sports with little protection, like hockey or baseball, you get ritualized fighting.
  • In sports with ritualized fighting, you get fight specialists. You don’t want skilled players getting injured.
  • In low fighting sports, like football, you need to slow things down with heavy referee intervention.
  • Once you  protect athletes with equipment, fighting goes up because it is less damaging.
  • If sports becomes lucrative, then norms change to reduce fighting. You don’t want your money generating stars missing the game.

A nice discussion of how norms, rules, and technology all affect each other.

“are you the last person in line?” – learning local norms

One of the somewhat terrifying or, for some of us, invigorating aspects of being an academic is learning and practicing cross-cultural and local norms, especially for research or travel. Typically, these lessons involve careful observation of what seems unthinkable (cutting in line?!? OR waiting one’s turn in line?!?), inadvertently breaking norms in front of aghast or amused locals, and the thrill of mastering a new skill.

In a few weeks, those of you who are relocating or returning to Britain might find the following links handy for immersion in the local milieu:

- “Feeling your life lacks excitement, so dunking your biscuit for an irresponsibly long time
- “The anxious bewilderment when clocking the stranger deciding to join the queue at your side rather than behind you
- “The unwelcome surprise of someone telling you how they are after you’ve asked them how they are”
- “Secretly hoping it stays cold so there’s always something to talk about”
- “Feeling guilty taking your M&S Bag For Life into Tesco

Coming to NYC for ASAs? Try season 8 of Curb Your Enthusiasm and brush up your “waiting on line” etiquette. Tip: don’t assume you’re at the back of the right line.

attention stratification researchers: we now have seven social classes, i repeat: we now have seven social classes

From the UK, a new survey, conducted by the BBC and six universities, asserts that there are now seven social classes in Britain. The Guardian has a humorous take, using example from UK sitcoms:

Elite: General Melchett from Blackadder Goes Fourth. Braying, bellowing, incompetent and utterly contemptuous of the lower orders, Melchett would naturally expect to find himself at the top of the pecking order.

Established middle class: Margot and Jerry Leadbetter from The Good Life. As the establishment pillars of comfortable and conservative 1970s suburban society, the couple existed in pointed contrast to their more free-thinking neighbours Tom and Barbara Good.

Technical middle class: David Brent from The Office. Despite his supposedly rock’n’roll past, Ricky Gervais’s fist-gnawingly embarrassing general manager was resolutely middle class.

New affluent workers: Miranda from Miranda. Miranda Hart herself may be established middle class, but the heroine of her eponymous sitcom sits comfortably in a slightly lower category.

Traditional working class: Jim Royle from The Royle Family. Could Ricky Tomlinson’s armchair-bound, TV-addicted patriarch be anything other than proudly working class? My arse!

Emergent service workers: Maurice Moss from the IT Crowd. Young, nerdish and living at home with his mum, Moss could fit the emergent service worker class but probably needs a little work to increase his social and cultural capital levels.

Precariat: Rab C Nesbitt. Gregor Fisher’s much-loved and enduring sitcom creation has assumed the status of folk hero despite his resolutely unglamorous life.

the dalluhn manuscript

A very learned commentary on the first edition of Dungeons and Dragons. For example, where “alignments” come from:

First of all, the paper explores crucial editorial mistakes in the production of the earliest version of original Dungeons & Dragons (OD&D). These are cases where some passages in OD&D are inconsistent with the remainder of the text in a way that hints at what early drafts of OD&D must have looked like. Previously, these have been curiosities to scholars of OD&D. Why does the elemental monster text refer to elemental controlling devices as “medallions, gems, stones or bracelets” instead of the names in the magical item list? Why does the languages passage refer to alignment languages as “divisional” languages? How did the percentage range for the “Ring of Delusion” end up broken? With the Dalluhn Manuscript in hand, we can find answers to all of these questions: each inconsistency points to the content of an earlier draft, a pre-publication system which is preserved in the Dalluhn Manuscript. For “divisional languages,” for example, we learn that “dvision” was the name for “alignment” in Dalluhn.

Required for nerds.

Posting will be light until January 2, 2013. If you want to write a post or two, send me an email with a short description. Long as it is is academic and fun, I’ll seriously consider it. In the Winter, we’ll have posts on the following:

  • a new book forum will be annnounced
  • digital natives vs. computer literacy
  • my endless anxiety about neo-institutionalism
  • progress in network analysis
  • The Hobbit was no Phantom Menace, but I’m still disappointed
  • a possibly cool research result
  • historians and the antiwar movement
  • the tragedy of the Fabios

summarize star wars in 1 tweet

A few days ago, the New Yorker asked people to summarize Star Wars in 1 tweet. The best tweet gets bragging rights. Given my obsession, I gave it a shot. I didn’t win, but I did get mentioned in the New Yorker:

We tried to notice trends in the mass of entries. Many participants knocked Luke Skywalker as whiny (@fabiorojas: “Whiny, but gifted, teenager trashes spiffy new military base”). Many expressed their belief that the film’s success came from its essential simplicity (@SnapShotPoet’s “How to throw an Emperor into a Deathstar for Dummies”). Many focussed not on Luke or Leia, but on the droids (@samanthaglavin’s “In a galaxy far far away, witty robots save stupid humans from trouble over and over again, set to a dramatic musical score”). Few, strangely, mentioned Chewbacca.

The winners:

But now, to the runners-up…. the first, @mattyshaz, let the movie’s title do the work for him: “‘Star Wars’ pretty much sums it up.” We were also attracted to the clumsy poetry of @JosaYoung’s summary (“When arm edited in bizarre light fitting accident, tall man attempts to conquer universe while breathing through coal scuttle”) and the stichomythia of @Matt_Kinson’s (“PLACE? Space WHEN? Then BOTS? Lots WHO? Leia Luke 3PO & R2. &? Han & Obiwan. WARS? Star. VS? Vader. END? Nada. WHY? SAGA”).The winner this week was selected in a special process, by a jury composed of two adults and two children. (“Star Wars” is, after all, a movie that appeals to us all.) After much consideration and some candy, the prize went to @MikeRudy’s summary, which had as much comic accuracy as a proton torpedo heading for an exhaust port: “‘He killed your dad!’ ‘But he is my dad!’ ‘And you’re my sister!’ Beep beep bloop.”

May the Schwartz be with you.
