The part of the human brain responsible for making complex decisions and judgments—the prefrontal cortex—does not come fully online until around age 25. Would it be better to raise the voting age, or leave it as is? What would happen if we raised it, according to your crystal ball?

In case your crystal ball finds it useful, the 18–29 segment made up 19% of the voters in the 2016 presidential election, and they voted 55/36 for Hillary. I couldn’t find anything for the 18–25 range in particular.
