Which Scientists Trashed the Public? According to a poll taken among scientists and reported in the prestigious journal Science (Mervis, 1998), scientists don't have much faith in either the public or the media. The article reported that based on the results of a "recent survey of 1400 professionals" in science and in journalism, 82% of scientists "strongly or somewhat agree" with the statement, "The U.S. public is gullible and believes in miracle cures or easy solutions."
