Judging Offenders With Intellectual Disabilities: Systematic Review of Criminal Justice System Professionals' Expressed Views and Attitudes Towards Offenders With Intellectual Disabilities.
Georgia Powell, Kate Blake-Holmes, Adela Petrache and 2 others
PMID 40390361WHAT IT FOUND
Criminal justice professionals often confuse intellectual disability with autism or mental health issues, relying on stereotypes rather than formal screening to identify it.
This leads to inconsistent support, where some offenders are diverted while others are treated as fully culpable. Specific, experiential training was the only factor reported to improve identification and confidence.
Key findings
01Professionals frequently conflate intellectual disability with mental health conditions or autism, prioritising mental health diagnoses at all stages of contact with the justice system.
02Identification of intellectual disability relies heavily on stereotypical cues like appearance and social background rather than formal screening, causing individuals with milder or masked disabilities to go undetected.
03Training was reported to improve understanding and confidence, but skills diminished without opportunities to apply them, and current training was often described as vague, basic, or superficial.

What it does not show
The quality of included studies was variable, with most lacking reflexivity regarding the researcher-participant relationship. The review is limited to English-language studies from Western, Common Law countries, reducing generalisability to other legal systems. The sample was heavily skewed towards police officers (596 of 766 participants), so findings may not accurately reflect the views of judges, magistrates, or lawyers. Searches were conducted primarily in health and medical databases, potentially missing relevant evidence from criminal justice or legal databases. Thematic synthesis removed quotes from their original context, which may have altered the nuance of the professionals' expressed views.
Declared interests
The authors declared no conflicts of interest. The review was registered on PROSPERO.
The easy way to misread this
Do not assume that training alone will solve identification failures. The review found that skills and confidence diminished without opportunities to apply them in practice, and current training was often described as vague or superficial. Effective intervention requires specific, experiential training combined with organisational pathways for formal screening, not just awareness sessions.
