Media, polling, public health, and risk

Highlights:

• PBS Now, interviewed for March 21, 2008, and a response to their editing. This followed some work I did  Media Claims Phthalates (Might) Cause Genital Defects and related work, published online at www.stats.org.  Subsequent appearance on NBC-7 News in Boston, ABC News in Washington D.C., and citation in the New York Times.
• College Rankings: F. Published in the Chronicle of Higher Education, Nov. 3, 2006.
• How Summers Offended (with G. Goldin and A. Foulkes). Published on the Washington Post, February 21, 2005. Subsequent appearances on National Public Radio and CNN.
• What Science Really Says About the Benefits of Breast-Feeding (and what the New York Times didn’t tell you), joint with E. Smyth and A. Foulkes. June 20, 2006. The theme of this piece was published as a letter to the editor the New York Times.

 

Many additional articles can be found online with STATS at www.stats.org. Recent in-depth topics include the health pros/cons to breastfeeding, the known and unknown impact of alcohol, the deaths in Iraq since the US invasion, and our statistical Frequently Asked Questions (FAQ) for journalists, now being used by the Annenberg School of Journalism. Additionally, I oversee work done by others at STATS including topics such as drug use/abuse, risky teen behavior, chemicals in everyday products, polling methods, divorce and marriage, and more.
