themselves state, however, "Acknowledging that our initial sampling process may have included non-expert individuals (e.g., anyone with an interest in intelligence can join ISIR), we filtered the sample to include only individuals with a doctorate degree, and having at least five career publications on the topic of intelligence or testing. This resulted in a final expert sample of N = 30." Given that their expert sample size was really only 30, this yields a response rate not of 38.3% as they claim, but of 30/94 =
158:. They got a total of 265 experts' responses on their survey, with only 75 experts answering the questions relevant to this study. The authors suggest that "The low response rates may reflect a paucity of experts on the secular rise in cognitive ability. There may be 20 to 50 scientists who study the development of intelligence throughout the world. Based on this estimate, the number of respondents in the current survey (N = 75) may even exceed the number of scientists who study the topic."

They reported that among their respondents, "here was consensus that cognitive ability tests are valid and fair, that they provide good but incomplete measures, that different abilities are necessary for different jobs, and that diversity is valuable. Items dealing with the unique status of cognitive ability were most likely to generate polarized opinions."

They found that "A total of 89% of the respondents regularly used profile analysis and almost 70% listed it as among the most beneficial feature of the WISC-III. Practitioners rated the WISC-III as very useful for determining diagnosis and educational placement, but less useful for developing instructional strategies and curriculum plans."
