Subclaims¶

q2 i? Haines argues that because many non-delinquent adolescents and adults have no more intelligence, a girl's delinquency cannot be saddled upon her intelligence; feeble-mindedness relevant to delinquency would lie in mental processes other than those measured by current intelligence tests. → Kohs 1917

Evidence¶

Kohs 1917¶

Kohs, S. C. (1917). An annotated bibliography of recent literature on the Binet-Simon scale (1913-1917). Part II. The Journal of Educational Psychology. https://doi.org/10.1037/h0073125

Quoted passage from the annotation of Haines (1916, Jour. of Delinq. 1: 154-155), "Defect in Germ Plasm as a Cause of Delinquency." The annotation continues that if feeble-mindedness is present, it is "in the realm of mental process other than those measured by intelligence tests now in use."

"The large number of non-delinquent adolescents and adults, who have no more intelligence, make it impossible to saddle the girl's delinquency upon her intelligence."

Discussion¶

Related Claims¶

• The year scale and the point scale yield disparate results and differ in diagnostic accuracy for delinquent populations, per Haines's studies — related
• Because many delinquent girls learned quickly and accurately, the article concludes moral defects must be partially explained on grounds other than inferior mentality — possibly the same claim (merge candidate)
• Large majorities of delinquent and reformatory girls tested with the Binet scale were classified feeble-minded — related
• Scattering on the Binet scales does not support the claim that unequal development is the specific characteristic of the feeble-minded; normal pupils scatter most and imbeciles least — related
