Excerpt from Eugenics and Public Health: A Lecture Delivered at the York Congress of the Royal Sanitary Institute, July 30th, 1912

Secondly - You may have the most conscientious district visitors, the most energetic staff of school medical officers, but if nothing has been done to standardise their judgments, the result will be hopeless confusion. I know from the schedules how the most conscientious assistant school medical officers, how the most enthusiastic and careful district visitors, differ in what we term their personal equation. One visitor finds 8 per cent. Of a certain characteristic, another working in an exactly similar or the same district finds 25 per cent. Even more anomalous results may be found in the school medical inspection returns. Yet in nine cases out of ten records are pooled without regard to this vital question of personal equation. Masses of material are indeed useless because no real attention has'been paid to this matter. There are methods of correcting for personal equation, there is nothing new in the problem, astronomers have felt the difficulty and met it for more than a century. But it is the application of an old theory to a new field, and if 10 per cent. Of public health officers have realised the difficulty, scarcely 1 per cent. Have attempted to meet it.
