In 1982, Cameron co-founded the Institute for the Scientific Investigation of Sexuality in Lincoln. Believing that earlier sex surveys, including those conducted by "Playboy" magazine, had overestimated the prevalence of homosexuality, Cameron set out in 1983 to conduct what he described as "a fair sexuality poll, not one based on volunteers." His expectation was that the results would support his case for a ban on homosexual acts throughout the United States. Funding, according to Cameron, was provided by businessmen including several Nebraska chief executives. The 1983 ISIS Survey, an "extensive self-administered questionnaire", was offered to 9,129 adults in five U.S. cities, and 4,340 responses were received. In 1984, these were supplemented with data from 824 adults from Dallas. Under the banner of ISIS, Cameron produced a number of "lurid pamphlets about the supposed social ills associated with homosexuality", containing numerous false or unverifiable claims.
