Steve Levitt runs a  consulting firm called The Greatest Good. It is occasionally hired by a philanthropist or foundation to look into societal problems. That’s what happened recently, when the Robert Wood Johnson Foundation asked The Greatest Good to put together a brainstorming session on childhood obesity. Stephen Dubner moderated the event. In this podcast, you get to be a fly on the wall as a dozen participants explore the biological, behavioral, political and economic angles of obesity. Read More »

FiveThirtyEighter Nate Silver Answers Your Questions About Politics, Baseball, and The Signal and the Noise

We recently solicited your questions for Nate Silver regarding his new book The Signal and the Noise: Why So Many Predictions Fail — But Some Don’t. Not too surprisingly, a lot of the questions were about politics and baseball. Below are Nate’s answers to some of them. Thanks to him for playing along and to all of you (as always) for sending in the excellent questions.

Q. Under what circumstances will a voter actually change his/her mind about whom to vote for? I understand that this rarely happens (this study for example), and that most of the action involves undecided voters deciding whom to vote for.

Also, if political scientist are right that voters rarely change their minds, how can a large swing in the polls ever occur? A classic example that your briefly mention in your book is that of Michael Dukakis, who was ahead of GHW Bush by 10% at one point in 1988. -Alan T

A. We see more big shifts in the primaries, when voters don’t have that much information about the candidates. Dukakis was a relative unknown at the start of the 1988 race, before the two parties could advance their own narratives. You rarely see big swings in voter conversion in late stage presidential races, though. If I knew how to cause such a swing, I’d be drawing a big salary from one of the campaigns right now.

What Makes a Rogue Trader Tick? A Q&A with FT Columnist John Gapper

The rogue trader is a recurring character in the story of finance over the last 20 years. This is the guy who makes secret, unauthorized bets with his bank’s money, driven by some seeming combination of inadequacy and a huge appetite for risk, and abetted at times by an amazing lack of internal controls.

The deeper he goes, the harder he has to work to conceal his deception until one day, it inevitably comes crashing down. The bank loses billions, the trader (sometimes) goes to jail. The story is repeated every several years. The latest version broke in September when UBS announced it had lost more than $2 billion as a result of rogue trader Kweku Adoboli.

In his new e-book, How to Be a Rogue Trader, Financial Times columnist John Gapper explains why this story has become so familiar over the years. As he puts it, the rogue trader is a species of sorts within the world of finance, a special breed with certain behaviors and characteristics that are consistent through time. Gapper delves into evolutionary biology and the research of Daniel Kahneman to better understand the nature of men like Nick Leeson, Joe Jett, and Jerome Kerviel. Read More »





Am I Good Enough to Compete In a Prediction Tournament?

Last spring, we posted on Phil Tetlock’s massive prediction tournament: Good Judgment. You might remember Tetlock from our latest Freakonomics Radio podcast, “The Folly of Prediction.” (You can download/subscribe at iTunes, get the RSS feed, or read the transcript here.)

Tetlock is a psychologist at the University of Pennsylvania, well-known for his book Expert Political Judgment, in which he tracked 80,000 predictions over the course of 20 years. Turns out that humans are not great at predicting the future, and experts do just a bit better than a random guessing strategy. Read More »





The Liberation of Use-Them-Or-Lose-Them Frequent Flyer Miles

This year, Daniel Kahneman has me wondering about what is the best way to organize my vacation time. In this great TED talk – The Riddle of Experience versus Memory, he talks about the tradeoffs we must make in increasing our moment-to-moment experience of happiness versus increasing our memories of happiness.

If you want to maximize your memories of happiness, you should spend more time taking pictures of your vacation and jam more events into each day. If you want to maximize your moment-to-moment experience of happiness, you spend less time recording your experience and more time experiencing them directly. Read More »





Sign Up for a Prediction Tournament

You may remember Phil Tetlock from our Freakonomics Radio hour-long episode “The Folly of Prediction.” He’s a psychologist at Penn and author of the deservedly well-regarded book Expert Political Judgment. Tetlock and some colleagues have embarked on an ambitious new study of prediction — and even better, they’re looking for volunteers. Specifically, they’re looking for people “who have a serious interest in and knowledge about world affairs, politics, and global economic matters and are interested in testing their own forecasting and reasoning skills.”

Doesn’t that sound like you? You need to be 18 or older, with a college degree. The project even pays a small honorarium. The start date has been pushed back to September, so you better act fast if you want in.

Here’s more information from Tetlock and colleagues: Read More »
