Would giving 16-year-olds the vote improve democracy or just change the way campaigns are run?

I think lowering the voting age is a fair concern because it is scientifically proven that if a person's prefrontal cortex is not yet developed they might tend to be more easily influenced by others. From an article I read from the National LIbrary of medicine I learned that the prefrontal cortex is a part of the brain that develops through the mid 20s and helps with looking at things in the long term plus being more rational. In the adolescent stage where it is not developed, young voters might do more emotional thinking than critical thinking. The adolescent brain is more responsive to a reward system and is more flexible therefore they are more responsive to their environment which might be their friend group or family. This may cause peer pressure to be another reason that younger voters might be more easily influenced. If it is a risk, one way to reduce it could be having more educational lessons about peer pressure and how to stand firm in one's own beliefs. However, another viewpoint could be that young voters can elect for who they truly think should be president without any doubt and influence by others. Youngsters are open minded to new experiences and motivated by climate change, education , gender disparities as all those issues affect their futures. Furthermore, age doesn't define an individual's understanding about politics and are willing to take others' perspectives into account. Secondly,I read in New Science of adolescence that there are two different types of thinking in a young person’s mind. One of them is called Hot cognition where a young person is in an emotional stage and thinks impulsively, this usually happens in a public setting like peer pressure at a party. Cold cognition is another type of thinking, this is a logical , analytical thinking used in quiet, low stress environments. When young people are at voting booths the environment is calm, organized and quiet. Revealing that they are most likely using cold cognition thinking while voting, and proving that they are not often peer pressured or influenced while voting.
