A substantial part of the U.S. population is “technologically illiterate,” according to experts at a National Technological Literacy Conference organized by the National Science Foundation and Pennsylvania State University. At this conference, the results of a national survey of 2,000 adults showed that:

• 72% do not understand the gross national product.
