Literally from that wiki article:

> There is no actual evidence suggesting that impulse control only finishes developing in humans in the twenties. It is a common misconception in popular psychology that the brain only fully develops by 25.[13] This may stem from a misinterpretation or oversimplification of studies which determined that development of the prefrontal cortex continues into the mid-twenties

Yes, I read it. The sentence before seems to imply that there is some change of rate of development around that age:

>Human brain maturation continues to around 20[10] to 25[11] and even up to 30[12] years of age and beyond.

I dunno, I don't think it implies that at all. It seems to imply that scientists have confirmed that growth is still occurring at that point, and not the other way around, especially given the rest of the article.
