Their frontal lobes are not fully formed yet.
This explains a lot of things. It means their brains make illogical conclusions. This is great if you’re a theoretical physicist. It’s why most discoveries are made by people under 35. It’s also why all the best engineers, technicians and the like are 35 and older. It requires a stable brain that can process all the inputs and come out with a logical conclusion without jumping over important steps.
For this reason, young people should not be making policy.
No one should be allowed to “make policy” until they prove they can hold down a job, pay their own bills, and keep their house in order. Being able to construct an “IM” should be celebrated about as much as being able to lick a stamp.
