“People with intellectual disability are easily targeted as crime victims” — society has, to some extent, absorbed that recognition. But that view captures only half of the picture.
“Intellectual disability” spans a wide range, from profound to mild, with the borderline range outside the medical category as well. Across IQ levels, the ways in which crime intersects vary sharply.
Some bands are mostly susceptible to victimization. Some bands also produce perpetration. And some produce perpetration in the form of abuse against one’s own child. This article walks through the relationship between IQ band and crime, level by level.
Profound and Severe (IQ 35 and below)
People at this level need care across all of daily life. Many also have physical disabilities and spend much of life in beds or wheelchairs.
If left alone, they would be defenseless against essentially any crime — but in practice, they almost always live in protected environments (facilities, hospitals), so they are rarely caught up in outside crime.
Within those facilities, however, they can suffer abuse from caregiving staff. That is not external crime; it is harm that occurs inside the protective environment.
On the perpetration side, motor delay typically accompanies the intellectual difficulty, and people unable to move freely rarely commit violence.
In the parenting context, a separate question arises. Cases of someone at this level becoming a parent are rare, but harm in the form of neglect of their own child can occur.
