Definition of intellectual disability in criminal court cases.

Olley (2013) read court opinions where judges decided if a person had intellectual disability.

He saw vague phrases like "subaverage intelligence" with no numbers.

The paper argues courts need clear, measurable words and must admit that test scores have error.

Courts often use fuzzy language that cannot be checked.

The study says judges should write exact IQ ranges, standard-error bands, and cultural limits right into the ruling.

Two years later Mukherjee et al. (2015) showed the Supreme Court did exactly that. Hall vs. Florida threw out a strict IQ 70 cutoff and told states to look at score bands plus daily-life skills.

Matson et al. (2013) and Luckasson et al. (2013) give the wider picture. Their two-part paper says every label we pick shapes policy and self-image. Gregory’s legal focus fits inside their call for careful, respectful wording.

Wang (2013) widens the lens further, warning that messy definitions hurt not only courtrooms but also school and health records. Together the four papers form one clear message: sloppy terms hurt real people.

If you write court reports, guardianship reviews, or testify on ID, swap soft phrases for hard numbers. State the IQ range, the standard error, and how culture or language may have affected scores. This small edit can keep a defendant off death row or get a student needed services.
