U.S. Supreme Court · 2012
567 U.S. 460 (2012)
Held that the Eighth Amendment forbids a sentencing scheme that mandates life without parole for juvenile homicide offenders. Before imposing that penalty a sentencer must consider youth and its hallmark features -- immaturity, impetuosity, and failure to appreciate risks and consequences -- and how children are different; given juveniles' diminished culpability and heightened capacity for change, such sentences should be uncommon.
Later courts have criticized, limited, or overruled this decision — verify it still holds.

Adolescents are more susceptible than adults to peer influence and to external pressure or coercion, with susceptibility greatest in mid-adolescence; the mere presence of peers measurably increases adolescents' risk-taking and shifts their decisions toward immediate rewards.
Adolescent personality and character are still forming and are not reliable indicators of fixed adult character; most adolescents who engage in antisocial behavior, including serious offending, desist as they mature, so adolescent conduct is a poor predictor of irretrievable depravity.
Adolescents weigh risks and rewards differently from adults: a reward-sensitive socio-emotional system matures earlier than the cognitive-control system, producing heightened reward-seeking, a weaker orientation to the future, and steeper discounting of delayed consequences during adolescence.
At the population level, childhood adversity — adverse childhood experiences (ACEs) such as abuse, neglect, and household dysfunction, and a harmful family or home environment — is associated with an elevated risk of adolescent antisocial and delinquent conduct, in a graded, dose-response pattern (more cumulative adversity, higher average risk).
Adolescents have a diminished capacity for self-regulation and impulse control relative to adults; the neural systems supporting cognitive control and behavioral inhibition mature gradually across adolescence and do not reach adult levels until the late teens to early twenties.
Sustained recovery and the consolidation of a prosocial identity in former criminal offenders depend significantly on the quality of prosocial bonds, community-based support networks, and genuine social integration, moving beyond purely individualistic or deficit-focused therapeutic models.
An earlier age at first conviction or arrest is a significant predictor of persistent and violent offending among justice-involved youth.
