[The] ability to make random choices or mimic a random process, such as coming up with hypothetical results for a series of coin flips, peaks around age 25, according to a study published in PLOS Computational Biology. Scientists believe that the ability to behave in a way that appears random arises from some of the most highly developed cognitive processes in humans, and may be connected to abilities such as human creativity. Previous studies have shown that aging diminishes a person's ability to behave randomly. However, it had been unclear how this ability evolves over a person's lifetime, nor had it been possible to assess the ways in which humans may behave randomly beyond simple statistical tests.

After controlling for characteristics such as gender, language, and education, they found that age was the only factor that affected the ability to behave randomly. This ability peaked at age 25, on average, and declined from then on.

"This experiment is a kind of reverse Turing test for random behavior, a test of strength between algorithms and humans," says study co-author Hector Zenil. "25 is, on average, the golden age when humans best outsmart computers," adds [co-author Nicolas] Gauvrit.

Interesting research.

This also dovetails with the 'Golden Age' of making stupid mistakes that require mom and dad to write a check.

"Previous studies have shown that aging diminishes a person's ability to behave randomly."

I'll give that a great big no $#!%. It's call living life and having responsibilities. But seriously yes creativity starts to slip away unless you use it all the time and you start to get "comfortable" (perhaps AKA "in a rut") when you are comfortable random doesn't serve you well at all that's called life experiences.

....until they cross a busy street randomly.

Age 25 makes perfect sense. Age 25 is when the brain quits growing at the rate that is was after puberty. Also, after about 10 years after puberty, hormone levels stabilize.

Study after study have concluded that people DO NOT act randomly. Especially young people.

it's called chaos theory.

the fun thing about chaos theory is that ultimately everything people do is based on simple cause and effect, i.e. not random or chaotic at all.

I think you are missing the point. If you are not then, I am. If I am please explain it to me.

The premise of the article is that age 25, people are most likely to act randomly...or in a chaotic manner, rather than one based on life experience.

It's not Chaos Theory, but I do think that the idea of the study is that the randomness of peoples actions is MOST pronounced at about age 25. And given my knowledge base, I would agree that the idea is backed up by a biological reason.
