We used Nexis to search for articles published in the New York Times and the Associated Press from January 1, 1985 through December 31, 2008 with the subject terms (race or racial or ethnic or Caucasian or African) and (genetic or genes or genomic). All articles selected by Nexis were read by one of two researchers trained to ascertain whether an article discussed genetic causes of a racial difference or discussed racial differences or similarities in genetic makeup (race per se). Inter-rater reliability (Cohen’s kappa) for selection of articles was .90. Among the Nexis-selected articles, 189 met our selection criteria. Detailed selection criteria and coding instructions for all variables are available from the first author.
