a non-representative sample of delinquent homosexuals (and Dr. Cameron compares this group to college and non-college heterosexuals)." Buchmeyer's decision was reversed by the Fifth Circuit on other grounds, without mentioning Buchmeyer's finding that Cameron had made misrepresentations. FRI has disputed Judge Buchmeyer's assessment of Cameron's affidavits. Epidemiologists Morten Frisch and Henrik Brønnum-Hansen argue that Cameron was wrong to infer reduced life expectancy from the fact that deaths among homosexually married partners in Denmark and Norway occurred at a lower median age than those among heterosexually married partners: "Because the age distribution among persons in same-sex marriages was considerably younger than that of people who had ever been heterosexually married, the average age at death among those who actually died during the observation period was, not surprisingly, considerably younger in the population of same-sex married persons." Their own analysis found that excess mortality in Danish same-sex marriages since 1995 was "restricted to the first few years after a marriage, presumably reflecting preexisting illness at the time of marriage". Similarly, critics have argued that obituaries in gay-themed newspapers, which Cameron used to estimate homosexual mortality, do not provide a representative sample of deaths and ignore surviving members of the same generation. Cameron has also been criticized for placing responsibility for same-sex child sexual abuse on "homosexuals"; Scientists say someone who carries out such abuse need not have a homosexual orientation with respect to other adults. Gregory M. Herek, a psychologist specializing in prejudice against sexual minorities, charges that Cameron misrepresented the literature he had reviewed and cited to support his claims, such as a Groth and Birnbaum (1978) study in which none of the participating child molestors actually identified as homosexuals, and none of those who were bisexual claimed to prefer men over women. Furthermore, while Cameron assumed all the same-sex molestations were perpetrated by homosexuals, he did not assume all the opposite-sex molestations were perpetrated by heterosexuals; he included a "bisexual correction" only for opposite-sex molestations that effectively increased the number of perpetrators described as "homosexual" without changing the number described as "heterosexual". Herek noted that most of the Cameron group's academic publications in the past 15 years have been based on a survey study conducted in 1983 and 1984. The main survey was completed in seven U.S. cities and towns in 1983. Data were later added from a 1984 Dallas (TX) sample. Most of the Cameron group's papers have reported
