Why Are We Still Using Cash?

Season 6, Episode 28 This week on Freakonomics Radio: cash facilitates crime, bribery and tax evasion – and yet some governments (including ours) are printing more cash than ever. Other countries, meanwhile, are ditching cash entirely. Plus: why thinking of Bitcoin as just a digital currency is like thinking about the Internet as just email. To find […]

“I Don’t Know What You’ve Done With My Husband But He’s A Changed Man”

Season 5, Episode 22 As we learned in last week’s episode, Cognitive Behavioral Therapy (CBT) has been effective in reducing criminal behavior among teenagers in Chicago and former child soldiers in Liberia. This week we go to England, where behavioral-therapy workshops for low-level domestic violence offenders have achieved a 40 percent reduction in repeat incidents […]

Preventing Crime for Pennies on the Dollar

Season 5, Episode 21

On this week’s episode of Freakonomics Radio: conventional crime-prevention programs tend to be expensive, onerous, and ineffective. Could something as simple (and cheap) as cognitive behavioral therapy (CBT) do the trick? First we go to Chicago, where at-risk teenagers who learn to be less impulsive have lower dropout and arrest rates.

Then, we take a look at Liberia, where a former child soldier and a team of researchers pair CBT with a cash incentive to help other former soldiers become productive citizens in peacetime.

Women Are Not Men: A Freakonomics Radio Rebroadcast

This week’s podcast is a rebroadcast of a show about all the ways that "Women Are Not Men."  (You can subscribe at iTunes, get the RSS feed, or listen via the media player above. You can also read the transcript, which includes credits for the music you’ll hear in the episode.) We take a look at the ways in which the gender gap is closing, and the ways in which it's not. You'll hear about the gender gap among editors of the world’s biggest encyclopedia, and what a study conducted in Tanzania and India has to say about female-male differences in competition. You'll also hear about the female happiness paradox and one of the biggest gender gaps out there: crime. Which begs the question: if you're rooting for women and men to become completely equal, should you root for women to commit more crimes?

Women Are Not Men

Season 4, Episode 1

Women are different from men, by a lot, in some key areas. For example, data show that women don’t: drown, compete as hard, get struck by lightning, use the Internet, edit Wikipedia, engage in delinquent behavior, or file patents as much as men do – and these are just some of the examples. Another way women are different from men? They have made significant economic gains and yet they are less happy now than they were 30 years ago. So, how do we explain this paradox? In this episode of Freakonomics Radio, Stephen Dubner looks at some of the ways that women are not men. Later in the hour, Dubner talks to Harvard psychologist Steven Pinker about his research on the history of violence. Pinker has a surprising and counterintuitive thesis: violence has declined and the world is a much more peaceful place than it has ever been.

Running to Do Evil: A New Freakonomics Radio Podcast

Our latest podcast is called "Running to Do Evil." (You can download/subscribe at iTunes, get the RSS feed, or listen via the media player above, or read the transcript.) It features a prison interview I did in 1999 with Unabomber Ted Kaczynski, whose younger brother, David, turned him in.

When we all learned last week that the alleged Boston Marathon bombers are brothers, it made me think of the massive leverage that an older brother can exert on a younger one. Ted and David Kaczynski were extraordinarily close for many years, and shared a view of the modern world as impure and overly industrialized. But as Ted went further down the path toward fundamentalism and violence, David not only extricated himself but ultimately made the painful decision to tell the FBI that the terrorist who had become known as the Unabomber was likely his brother.

Women Are Not Men: A New Freakonomics Radio Podcast

Our latest Freakonomics Radio podcast is called “Women Are Not Men.” (You can subscribe at iTunes, get the RSS feed, or listen via the media player above. You can also read the transcript below; it includes credits for the music you’ll hear in the episode.) 

As Stephen Dubner says: 

DUBNER: Equality of the sexes has long been a goal, and in many ways that goal is being met. But, as you’ll hear on this program, the variance between men and women on some dimensions is still large. ... We’re not trying to start any arguments. We’re just trying to look at the data that show differences between men and women to figure out why those differences exist, and how meaningful they are. 

The first story you'll hear is about the gender gap among editors of the world's biggest encyclopedia. Bourree Lam (the editor of this blog) looks at why only 16% of Wikipedia’s editors are female -- which is puzzling in that women outnumber men on Facebook, Twitter, Pinterest, and even in online games. 

Next, you'll hear about female-male differences in competition. Economist Uri Gneezy and a group of researchers got to study competition in the Masai tribe in Tanzania (which is extremely patriarchal) and the Khasi tribe in India (one of the world’s few matrilineal societies). When it comes to competition, Gneezy says, nurture is key:

How to Think About Guns: A New Freakonomics Radio Podcast

Our latest Freakonomics Radio podcast is called “How to Think About Guns.” (You can download/subscribe at iTunes, get the RSS feed, or listen via the media player in the post. You can also read the transcript below; it includes credits for the music you’ll hear in the episode.)

This episode is a straightforward conversation between Stephen Dubner and Steve Levitt, keeping in mind recent events like the Newtown, Ct., school massacre and long-standing traditions like the American embrace of guns.

Levitt has focused much of his academic career on crime research, including all sorts of gun policies that do and do not prevent violence.  He has also analyzed the relationship between the economy and the crime rate, whether increased police presence affects crime, and whether deterrents like capital punishment and sentence enhancements actually work.
