About the Manual of the Mental Examination of Aliens
Under the Immigration Act of 1907 and subsequent legislation, US Public Health Service physicians at ports of entry were required to identify arriving immigrants with mental defects, mental disease, or epilepsy. The intellectual disability category was particularly difficult to assess because most arriving immigrants did not speak English. The 1918 Manual codified the standard procedure.
The Manual prescribed a multi-stage examination. First, a brief visual screening of all arrivals as they walked through the inspection lines (the PHS officer would tag suspected cases with chalk marks). Second, a more thorough individual examination of tagged cases using non-verbal instruments where language was a barrier - typically Knox Cube, Healy Pictorial Completion, and Pintner-Paterson form boards. Third, for cases that remained ambiguous, a full Binet-Simon administration through a translator.
The Manual is a primary historical document for understanding how early-20th-century US immigration policy intersected with psychometrics. It is also an unflinching record of an era when intelligence testing was used in service of restrictive immigration policy. The Manual itself is a procedural document and largely free of overt eugenic content, but the procedures it describes were sometimes used to deny entry to thousands of immigrants flagged as mentally deficient.
