Spitz studied concepts such as mental age,^[1] and the abilities of autistic savants.^[2] He co-authored a survey of attempts to raise intelligence among people with intellectual disability.^[3] He reported on programs like the Carolina Abecedarian Early Intervention Project which advocated the early education of poor children.^[4] Through use of the Wechsler Adult Intelligence Scale, he reported that the Flynn effect of massive intelligence quotient gains in a single generation in many nations only applied to people in the average intelligence range.^[5] He also looked at the hereditarian hypothesis for general intelligence factor by examining Wechsler subtest patterns among test-takers with intellectual disability.^[6]

In 1994 he was one of 52 signatories on "Mainstream Science on Intelligence,^[7]" an editorial written by Linda Gottfredson and published in the Wall Street Journal, which declared the consensus of the signing scholars on the measurement and significance of intelligence following the publication of the book The Bell Curve.

Herman H. Spitz died in Natick, Massachusetts on February 11, 2019, at the age of 93.^[8]
