Mentally Defective Children

This is the landmark text that invented modern intelligence testing. Published in the early 1900s, Alfred Binet and Théodore Simon document their groundbreaking research into identifying children who could not thrive in standard classrooms. Through careful observation and innovative testing methods, the authors demonstrated that these children required specialized educational approaches tailored to their specific needs. The book argues passionately for a collaborative effort between educators, doctors, and psychologists to recognize these children early and provide appropriate support. Binet and Simon believed society had a moral obligation to develop pedagogical methods suited to different minds, not simply to sort and label children. While the terminology has inevitably evolved, this work remains essential reading for understanding the origins of educational psychology and the ongoing fight to recognize neurodiversity in learning.
