Did you know that the Stanford-Binet IQ test, when first translated to English in 1908 by Henry H Goddard, the scale used very different definitions to those used today?
Currently in its fith revision, the system uses ten groupings but the 1908 translation’s first three classifications were: 0 to 20 – Idiot; 20 to 49 – Imbecile; 50 to 69 – Moron (the average IQ being around 100).
Also, believe it or not mental retardation and learning difficulties were referred to as the spectacularly offensive “Feeble Minded“.
