Literally, this is exactly where this comes from.

He does this research.

He goes and gives a bunch of interviews about this research.

And in an interview he does with Time magazine, they ask him, you know, based on what you've been seeing in teenage brains and children's brains and adolescent brains and young adult brains, when do you think the brain fully develops?

And he quote, he says, if I had to pick a number right now, I'd probably say 25.

Now that number stuck because of what a prominent interviewer was.

The reason it was really prominent was because at the time, this was in America, they were debating the death penalty and basically like criminal implications for teenagers and

And for people in their early 20s in the US and whether people who were 17, 18, 19, 20, 21 could be deemed responsible for their actions, given this theory that their brains probably still reflected those of teenagers.

And, you know, why could it, it was basically like, why would somebody who was 15 be

not be given the death penalty but somebody who was 17 be given the death penalty or somebody who was 20 being given the death penalty when according to our research like the these brains the brains of these individuals look really really similar so it was a huge news story right it was it was a massive news story and that is where the 25 number comes from this interview that that this guy did this interview that that jay did where he said if i had to choose a number right now

25, despite the fact that their study did not include anybody who was 25.

And specifically to hone on this, like why was it the frontal lobe specifically that develops at 25?

Why not the whole brain?

Why was there such a focus on this?

That is because from that same research, the same scientists discovered that it was the frontal lobe that developed last.

So it just kind of made sense.

You know, the frontal lobe was the last piece of the puzzle.

When frontal lobe development was done, they said brain development was done.

When the frontal lobe clicked into place, that's when people could be seen as responsible.

Emotionally, morally, most importantly, criminally.
