Apparent conflicts of interest do affect public perception, according to a recent CSPI survey of 1000 adults. While 59% of respondents had confidence in a hypothetical statement from "a Harvard professor supported by government research" stating that a drug is safe, 48% had confidence when the statement was attributed just to a "Harvard professor," 41% when it was attributed to "a Harvard professor whose research is supported by drug companies," and 24% when the statement was attributed to "a Harvard professor who owns stock in drug companies."
