The clueless National Center for Science Education
A section describing survey results about the American public's beliefs about evolution and the Big Bang was removed from the 2010 edition of Science and Engineering Indicators. According to a post on the AAAS's Science Insider blog (April 8, 2010) and a subsequent report in Science (April 9, 2010; subscription required), although survey results about evolution and the Big Bang have regularly appeared in the National Science Board's Science and Engineering Indicators, its biennial compilation of global data about science, engineering, and technology, they were absent from the 2010 edition.
NCSE's Joshua Rosenau decried the decision, saying, "Discussing American science literacy without mentioning evolution is intellectual malpractice ... It downplays the controversy." . . .
. . . . . Officials at the National Science Board defended the decision. Louis Lanzerrotti, chair of the board's Science and Engineering Indicators committee, told Science that the questions were "flawed indicators of science knowledge because the responses conflated knowledge and beliefs."
"Responses conflated knowledge and belief"? "Belief" probably refers to religious belief. Another commenter said,
George Bishop, a political scientist at the University of Cincinnati who is familiar with the difficulties of polling about evolution, regarded that position as defensible, explaining, "Because of biblical traditions in American culture, that question is really a measure of belief, not knowledge."
Many people have the misconception that "belief" is defined as being religious only.
If the survey had only partly concerned the evolution v. religion issue, the survey probably would not have been deleted from the report, because the title of the report is very general, "Science and Engineering Indicators." Those who decided to delete the survey from the report probably assumed that the survey was only about religion (that's still not a good reason to delete it, but I am only trying to guess these people's thinking). And guess who is one of the biggest promoters of the idea that all opposition to evolution is religious? The NCSE. NCSE's Director Eugenie Scott said, "antievolutionism is uniformly the product of religious opposition," and NCSE "Faith Project Director" Peter Hess even went so far as to call opposition to evolution "blasphemous."
