Could lowering the voting age to 16 actually improve the quality of democratic elections?

In short: While the debate over lowering the voting age to 16 often centers on maturity, research suggests that adolescents possess the cognitive skills necessary for informed voting. Proponents argue that engaging younger citizens could foster lifelong habits, boost turnout, and ensure that laws affecting the future reflect the voices of the youth.

The push to lower the voting age is not new. In the United States, the voting age remained at 21 until the 1970s. The shift to 18 was driven by the Vietnam War, where the disparity between being drafted to fight and lacking the right to vote became a rallying cry for reform. The 26th Amendment, ratified in 1971, remains the fastest-ratified amendment in American history, passing in just three months. Today, while a national change would require a constitutional amendment, several local jurisdictions in states like California, Maryland, and Vermont have already lowered the age for local elections.

Scientific research provides a compelling case for the competence of 16-year-olds. A 2011 study in the Annals of the American Academy of Political and Social Science found that 16-year-olds perform similarly to adults on measures of civic knowledge, political skills, and tolerance. Experts note that 'cold cognition'—the ability to make well-thought-out, informed decisions—is already well-established by this age. International examples, such as Austria’s 2007 decision to lower the voting age, support these findings; researchers from the University of Vienna observed that younger voters cast ballots in ways that effectively represent their interests, matching the quality of older voters.

Beyond individual competence, there is a structural argument for earlier engagement. First-time voters often face logistical hurdles like registration and finding polling places. By voting while still in a structured high school environment, young people can receive guidance from teachers and parents, potentially establishing a habit that lasts a lifetime. Data shows that voting in one election increases the probability of voting in future elections by 13 percent. Furthermore, youth participation can have a 'trickle up' effect, mobilizing parents and other adults in the household to head to the polls, thereby increasing overall voter turnout.
