Brewer says his research is important because it says people are honest in what they report in surveys of sexual behavior. The problems weren't due to misreporting but to sampling errors, Brewer says. He concedes, however, his findings rely on three major studies estimating the number of prostitutes in the United States. Differences Between Men and Women Commenting on the research, Norman Brown, associate professor of psychology at the University of Alberta, in Edmonton, questioned the prostitute data. In his research, Brown has found men tend to give rough estimates of numbers, a strategy that leads to overestimation.
Women tend to count, an approach resulting in underestimation.
