Einstein once said "A person who has not made his great contribution to science before the

Einstein published four groundbreaking papers in 1905 when he was 26 and we describe him

as a genius - someone with exceptional intellectual ability.

So is there a point where we hit our intellectual peak? When we will be the smartest we’ll

Defining human intelligence is complex - I’ve mentioned previously that it includes your

capacity for reasoning, planning, problem-solving, abstract thought, self-awareness, communication,

One theory is that intelligence can be broken down into two types: crystallized and fluid

Fluid intelligence is the capacity to think logically and solve problems, independent

of acquired knowledge. Like how quickly you can solve this puzzle. Crystallized intelligence

is the ability to use the knowledge you’ve built up from what you’ve learnt. Like knowing

the elements of the periodic table or names of the spells in Harry Potter.

Placing a peak age on our cognitive skills is tricky, and depends on how we measure intelligence.

Tests of fluid intelligence show it peaks in young adulthood and slowly, gradually declines.

Crystallized intelligence remains much more stable and has been shown to decline as late

as our 70s. Is there a magical point where they meet?

In a 35-year-long study tests of general mental abilities showed that on average, your abilities

increase until your late 30s or early 40s. Mental abilities are stable until your mid

50s or early 60s. From your late 60s, thing start to decline.

The proportion of physicists who did their prize-winning work by age 30 peaked in 1923

at 31%. By the year 2000, this dropped to 0%. And prize winning work by age 40 occured

There’s no clear or easy way to tell when we’re at our brightest. And there are lots

of different opinions. So I asked you, to see if we could all piece together our thoughts.

In fields like math and physics, people tend to be the most creative and make the largest

impacts when they're very young, like early twenties. But I'm not sure that having revolutionary,

creative ideas is necessarily the same thing as being the smartest.

Like at your physical peak is also kind of when your brain is at it's peak.

I feel like you're the smartest you'll ever be, as judged by IQ tests, around the age

Let's throw a number out there, I'll say 65. There we go. It's like old enough to remember

all the things that I've learned over the course of my life but just on the edge of

when I'll probably start forgetting them.

Well I mean smartness is a complicated thing, but a lot of it has to do with experience,

right? And if you're constantly living a life where you're having new experiences, which

I think by definition you are people always have to be, then you are always smarter in

the current moment than you previously were.

I think I know a lot more now, and not just facts, but how things work, how the world

Because you can be very, very smart at any age.

And MindSponge wrote that maybe peak intelligence is dependent on the person

Williem van de Beek wrote that while famous scientists published their biggest discoveries

in their 20s, he feels smarter now in his 30s. Jack Freeman and Erik wrote that our

peak would be around 30, Just Having Fun wrote that the peak is in the late 40s, where people

have a wealth of experience and are still in good health.
