You've got it backward. The notion that criminals are simply ordinary people who find themselves in certain circumstances is the moralistic concept. It's something people want to be true, because it implies that we can reduce crime by fixing the circumstances that cause people to commit crime.

But science shows that criminals are literally wired differently. For example, the brains of youth homicide offenders are different than those of non-offenders. Computer models can actually predict future homicidal behavior from clinical data and brain scans: https://www.nature.com/articles/s41598-025-32782-5 ("Classification through machine learning models using these clinical and neural data predicted which formerly incarcerated youth committed a future homicide as adults with high accuracy.").

Similarly, we know traits such as ADHD are caused by brain chemistry rather than the environment. Compared to the general population, ADHD is over-represented in prison populations by a factor of 5 for youth and 10 for adults: https://pmc.ncbi.nlm.nih.gov/articles/PMC4301200/ ("Compared with published general population prevalence, there is a fivefold increase in prevalence of ADHD in youth prison populations (30.1%) and a 10-fold increase in adult prison populations (26.2%).").

Of course, none of that is to say we should do some pre-crime like process where we imprison people with ADHD who haven't done anything wrong. Instead, the point is that youth who commit serious crimes are disproportionately likely to be the ones who commit crimes due to factors intrinsic to the individual. That cuts against the popular notion that youth offenders are the ones who are more likely to be able to be "saved" through societal intervention. E.g., an adult drug dealer who shoots someone in an altercation over a drug deal may well be easier to rehabilitate than a teenager who shoots a classmate over social conflict.

Two things can be true at once. My point was about the quote I pulled. Other perspectives on the topic are a separate matter.

Regardless, science doesn't show how these differences form; this phrasing smuggles a nature over nurture perspective as a fact: "more likely to simply be bad people rather than people who happened to be in bad circumstances" (as well as "science shows that criminals are literally wired differently" and "the point is that youth who commit serious crimes are disproportionately likely to be the ones who commit crimes due to factors intrinsic to the individual"). My point is that the statements I quoted are not strictly true, they are what the author expects to be true; I suppose there may be some reason other than morals for said expectation but, seeing as you didn't deny my framing, instead reversing it, I suspect it is accurate.
