IN: Ryan Matthew Dunn (June 11, 1977 - June 20, 2011) was an American stunt performer, television personality, comedian, actor, writer, musician, and one of the stars of the MTV reality stunt show Jackass. Dunn rose to fame in the late 1990s as a member of the CKY Crew with his long-time friend, Bam Margera, for their extreme stunts and pranks recorded on camera, which led to the rise of Jackass. Dunn also hosted Homewrecker and Proving Ground, and appeared in the feature films Blonde Ambition and Street Dreams, as well as in Margera's films Haggard and Minghags. Dunn died in a car crash in 2011, on the 10th anniversary of Jackass.

Dunn took part in the characteristic stunts that made Jackass famous, and featured in all three released films, Jackass: The Movie, Jackass Number Two and Jackass 3D.  In 2006, Dunn and Bam Margera participated in the Gumball 3000 road rally in Margera's Lamborghini Gallardo. He later went on a tour with Don Vito called "The Dunn and Vito Rock Tour" for which the DVD was released on March 20, 2007. Dunn and Margera again participated in the rally in 2008.  Bam Margera stated during a December 2, 2008, radio interview with Big O and Dukes of 106.7 WJFK-FM, that he and Dunn would be going to Italy to film Where the F*%# Are My Ancestors. That same month, Dunn appeared on the episode "Smut" of Law & Order: Special Victims Unit in December 2008. He is also featured in a movie called Street Dreams which was released in spring 2009. He co-starred along with Rob Dyrdek and Paul Rodriguez Jr. Dunn was also featured on a show with fellow Jackass star Bam Margera about them traveling through Europe in a Viva la Bam-like show called Bam's World Domination for Spike. He appeared in Jackass 3D, which was released on October 15, 2010.  Dunn co-hosted G4's Proving Ground along with Jessica Chobot, which made its premiere on June 14, 2011, six days before his death. However, according to a G4 spokesperson, the channel decided to postpone the airing of further episodes. The spokesperson added, "The show is off the schedule as of today until we discuss next steps." On June 27, G4 announced they would air the remaining episodes starting on July 19, 2011. At the time of his death, Dunn was working on the film Welcome to the Bates Motel. The film was later renamed The Bates Haunting and was released in 2013.

IN: Steven David "Steve" Levitt (born May 29, 1967) is an American economist known for his work in the field of crime, in particular on the link between legalized abortion and crime rates. Winner of the 2003 John Bates Clark Medal, he is currently the William B. Ogden Distinguished Service Professor of Economics at the University of Chicago, director of the Becker Center on Chicago Price Theory at the University of Chicago Booth School of Business. He was co-editor of the Journal of Political Economy published by the University of Chicago Press until December 2007. With journalist Stephen J. Dubner, he co-authored the best-selling book Freakonomics (2005) and its sequels SuperFreakonomics (2009)

See The Impact of Legalized Abortion on Crime for a detailed discussion of the issue.  Revisiting a question first studied empirically in the 1960s, Donohue and Levitt argued that the legalization of abortion can account for almost half of the reduction in crime witnessed in the 1990s. This paper has sparked much controversy, to which Levitt has said  "The numbers we're talking about, in terms of crime, are absolutely trivial when you compare it to the broader debate on abortion. From a pro-life view of the world: If abortion is murder then we have a million murders a year through abortion. And the few thousand homicides that will be prevented according to our analysis are just nothing--they are a pebble in the ocean relative to the tragedy that is abortion. So, my own view, when we [did] the study and it hasn't changed is that: our study shouldn't change anybody's opinion about whether abortion should be legal and easily available or not. It's really a study about crime, not abortion."  In 2003, Theodore Joyce argued that legalized abortion had little impact on crime, contradicting Donohue and Levitt's results ("Did Legalized Abortion Lower Crime?" Journal of Human Resources, 2003, 38(1), pp. 1 -37.). In 2004, the authors published a response, in which they claimed Joyce's argument was flawed due to omitted-variable bias.  In November 2005, Federal Reserve Bank of Boston economist Christopher Foote and his research assistant Christopher Goetz, published a working paper, in which they argued that the results in Donohue and Levitt's abortion and crime paper were due to statistical errors made by the authors: the omission of state-year interactions and the use of the total number of arrests instead of the arrest rate in explaining changes in the murder rate. When the corrections were made, Foote and Goetz argued that abortion actually increased violent crime instead of decreasing it and did not affect property crime. They even concluded that the majority of women who had abortions in the 1970s were middle class whites rather than low income minorities as Levitt stated; this was, they stated, because white middle class women had the financial means for an abortion. The Economist remarked on the news of the errors that "for someone of Mr Levitt's iconoclasm and ingenuity, technical ineptitude is a much graver charge than moral turpitude. To be politically incorrect is one thing; to be simply incorrect quite another." In January 2006, Donohue and Levitt published a response, in which they admitted the errors in their original paper but also pointed out Foote and Goetz's correction was flawed due to heavy attenuation bias. The authors argued that, after making necessary changes to fix the original errors, the corrected link between abortion and crime was now weaker but still statistically significant, contrary to Foote and Goetz's claims. Foote and Goetz, however, soon produced a rebuttal of their own and showed that even after analyzing the data using the methods that Levitt and Donohue recommend, the data does not show a positive correlation between abortion rates and crime rates. They are quick to point out that this does not necessarily disprove Levitt's thesis, however, and emphasize that with data this messy and incomplete, it is in all likelihood not even possible to prove or disprove Donohue and Levitt's conclusion.
