    The whole “human brains aren’t fully developed until you’re 25” is such an annoying quote that gets thrown around by people just because they’ve heard it online.

    I swear half the time it’s used to infantise young adults. I’m glad people weren’t pedalling this pseudoscience “fact” when I was that age, it’d probably get on my nerves.

    It’s based on essentially nothing.

    There isn’t an age where your brain is done developing. It constantly changes all throughout your life, affected by a whole load of factors we don’t really understand yet.

    It certainly goes through periods of rapid change, but this happens predominantly years before you’re 25, or after life-changing events that alter how you think - things like moving out and having to manage your own life more, moving country to a very different culture/language, entering a LTR, having children, using drugs, getting a job, losing family members, even learning to drive can have a profound effect on your brain, evidenced by MRI scans.

    Much of that stuff happens in your early-mid twenties, so I see why people would erroneously think that it’s the turning 25 part that does it.

      I actually learned it in university studying biology. Which was some time ago and I didn’t follow up on research. But if I remember correctly there is rather large deviation on individual level.
