Are children's carseats necessary? Steven Levitt on TED.com

tedstaff — Tue, 24 Jun 2008 08:21:22 +0000

Economist Steven Levitt shares provocative data that shows carseats are no more effective than seatbelts in protecting kids from dying in cars. However, during the Q&A, he makes one crucial caveat. (Recorded July 2005 in Oxford, UK. Duration: 19:04.)

Vote for your favorite public intellectuals

tedstaff — Thu, 01 May 2008 13:28:31 +0000

Not to be outdone by the Time 100, the journals Foreign Policy and Prospect have together released a list of the Top 100 public intellectuals — with voting. Many TEDTalks favorites appear on the list, and you can help choose the eventual top 20 by voting for your very own top 5. From Foreign Policy‘s site:

Although the men and women on this list are some of the world’s most sophisticated thinkers, the criteria to make the list could not be more simple. Candidates must be living and still active in public life. They must have shown distinction in their particular field as well as an ability to influence wider debate, often far beyond the borders of their own country.

TEDTalks speakers on this top 100 list include George Ayittey, Steven Pinker, Neil Gershenfeld, Malcolm Gladwell, Craig Venter, Al Gore, Richard Dawkins, Vilayanur Ramachandran, Larry Lessig, Steven Levitt, E.O. Wilson, Dan Dennett and Bjorn Lomborg — and look for upcoming TEDTalks from others on this list, including Paul Collier, who spoke at TED2008 about “the bottom billion.”

"Crack economics" researcher tells his story

tedstaff — Sun, 13 Jan 2008 04:00:00 +0000

Stephen Levitt calls him the “main character” in his TEDTalk on crack economics: Sudhir Venkatesh, the young grad student who infiltrated a Chicago crack-dealing gang. His research brought back reams of sociological data — and offers an unfiltered glimpse into gang life. In his new book, Gang Leader for a Day, Venkatesh writes about his experiences during the six years he spent with the Black Kings gang in Chicago’s Robert Taylor Homes. Venkatesh is interviewed on NPR, whose site also offers an excerpt from his book, while the Chicago Sun-Times has an MP3 of the author reading his work.

A freak blog migrates into an institution

bgiussani — Tue, 14 Aug 2007 08:07:21 +0000

After over two years at freakonomics.com, Steven Levitt and Stephen Dubner – co-authors of the 3-million-copies "Freakonomics" — last week moved their blog under a bigger and more institutional brand, that of the Opinion section of the New York Times’ website.

Levitt spoke at TED2004 offering a preview of a chapter of "Freakonomics" titled "Why do crack dealers still live with their moms?" (watch the video) and exposing his very unconventional approach to economic analysis.

The migration of the blog wouldn’t be a remarkable event (even though the blog is very interesting and highly interactive, attracting hundreds of readers’ comments) were it not for two facts. The move, in a way, closes a circle: "Freakonomics" was born from a profile that Dubner wrote about Levitt for the New York Times Magazine in 2003, "The Economist of Odd Questions". It also underscores a nascent trend, that of well-known bloggers moving into newspapers’ and magazines’ websites, creating synergies and pooling readerships — another step towards the hybridization of the media. The NYT is not the first to try this strategy: France’s Le Monde, for example, has been doing so for a while.

Malcolm Gladwell & Steven Levitt: It started at a TED salon …

tedconfjune — Wed, 14 Jun 2006 11:16:57 +0000

A great TED tidbit we missed the first time around: In TIME Magazine last month, Tipping Point author Malcolm Gladwell (TED04) wrote a tribute to Freakonomics author Steven Levitt (TED04, TEDGlobal), who was honored as one of the TIME 100. It starts like this:

Not long after Freakonomics came out, Steven Levitt and I had a public debate at a salon in downtown Manhattan. The subject was crime. In my book The Tipping Point, I had argued that the cluster of innovative policing strategies known as “broken windows” played a big role in the dramatic drop in New York City’s crime rate. Levitt and his co-author Stephen Dubner argued, to the contrary, that “broken windows” was an illusion and that other factors, like the demographic changes brought about by the legalization of abortion, played a much bigger role. It was a straightforward back-and-forth. Levitt got up and made his case. I got up and made mine. But halfway through, I glanced over at Levitt and had a realization that I’m not sure I’ve ever had before with an intellectual opponent—that if I made my case persuasively and cogently enough, he would change his mind. He was, in other words, listening. More >>

The above-mentioned event was, course, a TED salon. Held at the TED loft in Tribeca, it featured the friendly, timely debate between Gladwell and Levitt, the week Freakonomics was published. Very pleased to see the salon had as much impact on them as it did on us!

Gladwell v. Levitt, Round 2

tedconfjune — Thu, 16 Mar 2006 12:27:29 +0000

At a landmark TED salon last spring, economist Steven Levitt and author Malcolm Gladwell crossed swords over the real reason New York City crime dropped in the 90s. In The Tipping Point, Gladwell credited the innovative policing tactics adopted under NYC Mayor Giuliani (which focused on softer “lifestyle crimes,” like subway graffiti and zoning violations) for the reduced murder rate. At the salon — and in Freakonomics (which had just been published that week) — Levitt begged to differ. The hidden cause, he argued, was the legalization of abortion, which had prevented thousands of unwanted children from being born roughly 20 years earlier. (Levitt further argued that New York’s drop in violent crime was merely the leading edge of a nationwide trend, consistent with the timing of respective states’ abortion laws).

Who had the last word? Well that’s an open question … Nearly a year later, they’ve picked up the thread, trading persuasive posts on their respective blogs. Gladwell re-opened the discussion, Levitt and Dubner responded. And you can watch it progress from there …

Steve Levitt, Freakonomics, abortion and crime

tedchris — Tue, 06 Dec 2005 10:58:28 +0000

TED speaker Steve Levitt, author of the best-selling Freakonomics, faced new accusations this past week that he’d made critical mistakes in his controversial claim that the main reason crime rates fell in the 90′s was because of the legalization of abortion in the 70′s. At his blog, he’s just posted a vigorous defence. The debate may be too technical for us mere lay-people, but it’s clear he’s not backing down.
