What’s the smartest age? - Shannon Odell

Video Overview & Insights

At what age are you smartest? Dig into how your brain development affects your skills at different stages of your life.

Experience is a lot more important than age. Atleast that's what I think

— @AashirwadClinic1

Tomorrow is the annual Brain Clash — a decathlon of mental challenges, trivia competitions, and puzzles. Amir needs a smart and capable teammate and must choose between three people; all of different ages and talents. So, who should Amir choose for the contest? Shannon Odell breaks down the idea of “smart” and explores how our brain development impacts our skills at various stages of our lives.

Me 13 years old😅

Useless video. Did not answer the question.

I think the age at which the brain is at it's most powerful is sometime around 8 and 10. After that, it's all experience that are making you smart.

People that think watching is 'is useless' don't get the point, this video is literaly to get you smarter at being nuanced.

I kinda predicted it wasn't one number 😝 different people could be problem solving, intuitive, booksmart, practical smart, capable, learning easy, and in some weird way I even find complexity at times easier than simple things

Mostly feel like there's always some one better than me. Gladly reality teaches nuance and different capabilities, being smart also comes with so many niches.

I'm 28 and I generally say that wisdom comes with age. And I am definitely a better version compared to when I was 12 or 18.

Practically people are getting smarter with every bit of knowledge "the more you know", and creativity usually isn't what people think it is ✨

And actually got smarter with this vid 💁‍♂️

I want to answer that question as an adolescent. I think the smartest age is 14–20… yeah, of course not everyone is the same, but have you guys ever noticed that people between 14 and 20 are more active? They want to try new things, and their brain works faster than that of older people or children. For example, me… since I was 14, I have been trying everything 😅. One day I want to be a cabin crew, but the next day I want to be a CEO, etc.

There is no single "smartest" age, as different cognitive abilities peak at different times, though research suggests overall psychological functioning and crystallized intelligence (wisdom/vocabulary) often peak between 55 and 60. While raw processing speed and memory tend to peak in the 20s or 30s, emotional intelligence and critical thinking continue to improve later.

This video explains that different brain skills peak at different ages:

Key Cognitive Peaks by Age:
Processing Speed: Peaks around age 18-19.
Short-Term Memory: Peaks around age 25.
Face Recognition/Learning: Peaks after age 30.
Emotion Recognition: Peaks around age 40-48.
Arithmetic/Basic Math: Peaks around age 50.
Vocabulary/Wisdom: Peaks in the late 60s to early 70s.

Key Findings on Intelligence:
Midlife Peak (55-60): A Facebook post argues this is the "smartest" age, combining emotional stability, conscientiousness, and complex reasoning.
Fluid vs. Crystallized: Fluid intelligence (solving new problems) peaks young, while crystallized intelligence (using accumulated knowledge) improves with age.
Ongoing Growth: Cognitive ability is a lifelong process; rather than a single peak, the brain adapts to prioritize skills necessary at different life stages, notes YouTube video.

funny, in chess, after 30/35 players start to decline. Most often retire from professional chess at the age of 40.
On the other hand, you have kids that are 12 reaching the Grandmaster level.

I do not think one can say that 65 if a good age for chess, on the contrary
