“In retrospect, we shouldn’t have omit-ted that text from the 2010 Indicators,” says José-Marie Griffiths, who took over as chair of NSB’s Indicators subcommit-tee when the term of the former chair, Louis
Lanzerotti, expired in May 2010. Griffiths says the 2012 Indicators will reinstate the section and include a sidebar explaining the board’s plans for revamping the survey. And for the fi rst time, the book will include a com-parison of knowledge indices—a metric of overall science literacy—measured with and without the evolution and big bang questions.
