> The study that appeared to show them stopping development at 25 did not have any participants older than 25.
Its not one study, its a multitude of studies of a different functions, and the popular conception about “brain development” not being full until the mid 20s is specifically about where multiple studies show the average peak in executive function occurs (with a slow decline after the peak, which obviously wouldn't be seen if it was only based on studies of younger people.)
Other functions peak anywhere from a little earlier, to much later, to, in a few cases, continuing to develop without a discernible age-related peak.
