In 1931 the newly founded Scottish Council for Research in Education decided to describe the mental ability of Scotland’s children. This was part of an international collaboration called the International Examinations Inquiry. Professor Sir Godfrey Thomson was at the heart of this project – assessing the intelligence of Scotland’s 11-year-old population in the Scottish mental surveys (1932 and 1947). This lecture first explains why Scotland was a world-leader in intelligence research; the obscurity into which Thomson and those Surveys fell; and how Thomson’s contributions are today re-emerging. Secondly, it describes current follow-up studies of the Surveys – exploring differences in cognitive ageing by testing the health, cognitive abilities and brain structure of people now in their 8th and 9th decades on whom there are intelligence test scores from age 11.
