> 6-8 years before their higher level thinking pre-frontal cortex fully develops This is a myth. The prefrontal cortex doesn't appear to ever stop developing. Early brain development studies involving MRIs simply only looked at people up to the age of 25 and the findings that they "develop until at least 25" turned into this myth that they stop developing and are "fully mature" at 25. The age of majority was a conservative choice based on society's view of when the vast majority of people were capable of the level of self-sufficiency required to do things like enter into contracts. If most are incapable of self-sufficiency without a parental guardian, then the age of majority should be increased. That said, we also ignored our own rationale and started allowing minors to apply for student loans. This is a travesty. https://www.sciencefocus.com/comment/brain-myth-25-development https://www.sciencefocus.com/comment/brain-myth-25-developme...
