What this article is
The "brain matures at 25" myth or "twenty-five year old brain" myth is the belief that the human brain reaches an adult level of maturity approximately around age 25. This interpretation is widespread in the media and public discourse and appears in some scientific literature. It has taken on multiple variations. The most common relates to the prefrontal cortex of the brain and its role in functions such as decision-making, long-term planning, risk assessment, and impulse control. The prefrontal cortex has been shown to mature at a slower rate than other parts of the brain. This finding has been widely cited in popular media, public discourse, and some policy contexts to argue that individuals under 25 years of age do not have mature decision-making capabilities. Its exact origin is unclear, but some have pointed to the research of neuroscientist Jay Giedd.

How this was measured
Views are Wikimedia's own pageview counts for en.wikipedia, filtered to agent=user so automated traffic is excluded. The baseline is the median of the previous 60 days, which is used instead of the mean so that an earlier surge cannot flatten a later one. The multiple is the day's views divided by that median.
