In 1990, Admiral James Watkins, the Secretary of Energy, commissioned the Sandia Laboratories in New Mexico to document the decline in the "Nation at Risk" report with actual data. When the systems scientists broke down the SAT test scores into subgroups, they discovered contradictory data. While the overall average scores declined, the subgroups of students increased. In statistics this is known as Simpson's paradox. The three authors presented their report. David Kearns, Deputy Secretary of Education allegedly told the authors of the report, "You bury this or I'll bury you." Diane Ravitch disputes this quote. "Education Week" published an article on the Sandia report in 1991. Unlike the "Nation at Risk" report, the Sandia Report critique received almost no attention.
