Abstract
From 1929 until 1972, the Alberta Eugenics Board (the Board) recommended that 4,739 individuals be sterilized. The original 1928 act that legalized eugenic sterilization stipulated that the surgery itself required the consent of the individual or their caregiver; however, in 1937, the Alberta government removed the consent requirement for such cases where the Board determined individual patients to be "mental defectives." By analyzing published reports, case histories, medical journals, and primary sources from the Board, we situate the concept of "mental defective" in a historical context to clarify the Board's diagnostic process. By analyzing how the Board found individuals to be "mental defectives," we challenge a previous historiographic assumption that intelligence tests played a critical or defining role in this diagnostic process. We argue that the notion of the "mental defective" used by the Board had a long history before the advent of intelligence testing and eugenic thought. This history helps to explain how and why the Board relied extensively on the broader examination of behavior, social status, and physical appearance as core evidence in the diagnosis of "mental defect." Intelligence tests were certainly important as they shed light on an individual's academic ability. However, this alone was only one part of "mentality." Defects of mentality were understood to be broad and multifactorial, and included difficult, if not impossible, to measure attributes such as personality, emotionality, and morality. Further research should incorporate the concept of mentality in the history of psychology, testing, and eugenics. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
