The Issue

In the state of Arkansas, the legal age of adulthood is currently set at 18 years old. However, a growing body of research indicates that the human brain continues to develop well into the mid twenties. This suggests that individuals at 18 may not fully possess the cognitive abilities necessary to undertake the responsibilities and make the consequential decisions that adulthood demands.

Yet at the same time, 18–20 year-olds are restricted from alcohol, cigarettes, renting cars, certain financial decisions, and other responsibilities because the state recognizes they are still vulnerable and not fully mature. This inconsistency puts young people at risk and creates unfair expectations.

According to a National Institute of Mental Health study, the brain's frontal lobe, which governs decision-making and rational thought, continues to develop into the mid-20s. By raising the legal age of adulthood to 21, we align legal responsibility with developmental maturity, ensuring that individuals have the necessary cognitive resources to make informed and thoughtful decisions.

Furthermore, states like Illinois and Mississippi have already taken steps to raise the age for some adult responsibilities, recognizing the same developmental science that solidifies our argument for change in Arkansas.

Raising the legal age to 21 could also positively impact the criminal justice system. Young individuals, currently treated as adults, could benefit from a juvenile justice system that offers rehabilitative, rather than punitive, approaches appropriate to their developmental stage.

This change could dramatically alter the trajectory of many young lives in Arkansas, fostering a more responsible, considerate, and prepared adult population. Join us in advocating for this crucial change, aligning our laws with scientific understanding and ensuring a brighter future for Arkansas youth.

Please sign this petition to urge Arkansas legislators to raise the legal age of adulthood to 21.
