Introduction: People in Chicago are nice. The conductor on the train came by and I asked if I could buy a ticket right there. He said yes, $2.50. While I was getting the money he asked if the ticket machine at the station had been broken. I said, I don’t know, I saw the train and ran up the stairs to catch it. He said, that’s not what you’re supposed to say. So I said, that’s right, the machine was broken. It’s just like on that radio show where Peter Sagal hems and haws to clue the contestant in that his guess is wrong so he can try again.

2 0.28177726 1245 andrew gelman stats-2012-04-03-Redundancy and efficiency: In praise of Penn Station

Introduction: In reaction to this news article by Michael Kimmelman, I’d like to repost this from four years ago: Walking through Penn Station in New York, I remembered how much I love its open structure. By “open,” I don’t mean bright and airy. I mean “open” in a topological sense. The station has three below-ground levels–the uppermost has ticket counters (and, what is more relevant nowadays, ticket machines), some crappy stores and restaurants, and a crappy waiting area. The middle level has Long Island Rail Road ticket counters, some more crappy stores and restaurants, and entrances to the 7th and 8th Avenue subway lines. The lower level has train tracks and platforms. There are stairs, escalators, and elevators going everywhere. As a result, it’s easy to get around, there are lots of shortcuts, and the train loads fast–some people come down the escalators and elevators from the top level, others take the stairs from the middle level. The powers-that-be keep threatening to spend a coupl

Introduction: Ooooooh, I never ever thought I’d have a legitimate excuse to tell this story, and now I do! The story took place many years ago, but first I have to tell you what made me think of it: Rasmus Bååth posted the following comment last month: On airplane tickets a Swedish “å” is written as “aa” resulting in Rasmus Baaaath. Once I bought a ticket online and five minutes later a guy from Lufthansa calls me and asks if I misspelled my name… OK, now here’s my story (which is not nearly as good). A long time ago (but when I was already an adult), I was in England for some reason, and I thought I’d take a day trip from London to Bath. So here I am on line, trying to think of what to say at the ticket counter. I remember that in England, they call Bath, Bahth. So, should I ask for “a ticket to Bahth”? I’m not sure, I’m afraid that it will sound silly, like I’m trying to fake an English accent. So, when I get to the front of the line, I say, hesitantly, “I’d like a ticket to Bath?

Introduction: I gave this talk the other day and afterwards, a white guy came up to me and said he thought it was no coincidence that the researcher who made the mistake was “Oriental.” He then went on for about 5 minutes explaining his theory. I couldn’t keep myself from laughing—I had to start coughing into a napkin to hide it.

Introduction: Felix Salmon relates the story of an economics Nobel Prize winner getting paid by a hedge fund. It would all seems pretty silly—sort of like Coca-Cola featuring Michael Jordan in their ads—except that hedge funds are disreputable nowadays and so it seems vaguely sleazy for a scholar to trade on his academic reputation to make free money in this way. It falls roughly in the same category as that notorious b-school prof in Inside Job who got $125K for writing a b.s. report about the financial stability of Iceland—and then, when they came back to him later and asked how he could’ve written it, he basically said: Hey, I don’t know anything about Iceland, I was just taking their money! That said, if a hedge fund offered me $125K to sit on their board, I’d probably take it! It’s hard to turn down free money. Or maybe not, I don’t really know. So far, when companies have paid me $, it’s been to do something for them, to consult or give a short course. I’d like to think that if

5 0.64125812 1316 andrew gelman stats-2012-05-12-black and Black, white and White

Introduction: I’ve always thought it looked strange to see people referred to in print as Black or White rather than black or white. For example consider this sentence: “A black guy was walking down the street and he saw a bunch of white guys standing around.” That looks fine, whereas “A Black guy was walking down the street and he saw a bunch of White guys standing around”—that looks weird to me, as if the encounter was taking place in an Ethnic Studies seminar. But maybe I’m wrong on this. Jay Livingston argues that black and white are colors whereas Black and White are races (or, as I would prefer to say, ethnic categories) and illustrates with this picture of a white person and a White person: In conversation, I sometimes talk about pink people, brown people, and tan people, but that won’t work in a research paper. P.S. I suspect Carp will argue that I’m being naive: meanings of words change across contexts and over time. To which I reply: Sure, but I still have to choose h

Introduction: Now that you have some free time again, you’ll have to check out these books and tell us if they’re worth reading. Claire Kirch reports : Lizzie Skurnick Books launches in September with the release of Debutante Hill by Lois Duncan. The novel, which was originally published by Dodd, Mead, in 1958, has been out of print for about three decades. The other books on the initial list, all reissues, are A Long Day in November by Ernest J. Gaines (originally published in 1971), Happy Endings Are All Alike by Sandra Scoppettone (1979), I’ll Love You When You’re More Like Me by M.E. Kerr (1977), Secret Lives by Berthe Amoss (1979), To All My Fans, With Love, From Sylvie by Ellen Conford (1982), and Me and Fat Glenda by Lila Perl (1972). . . . Noting that many of the books of that era beloved by teen boys are still in print – such as Isaac Asimov’s novels and The Chocolate War by Robert Cormier – Skurnick pointed out that, in contrast, many of the books that were embraced by teen gir
