> Fluid intelligence, which peaks near age 20 and declines materially across adulthood [...] while fluid intelligence may decline with age, other dimensions improve (e.g., crystallized intelligence, emotional intelligence)

As someone well past "peak" fluid intelligence at this point, I always hate reading research like this. "Crystallized intelligence" and "emotional intelligence" are the consolation prizes no one really wants.

I'd rather we instead perform research to identify how one might reverse the decline of fluid intelligence...

> are the consolation prizes no one really wants.

If you can't figure out how to use accumulated knowledge and advanced people skills by your late 30s, then maybe you weren't so rational or adaptable to new situations in the first place. Things may not click for me like they did when I was 25, but I usually see right away when I have relevant knowledge to solve a problem or when I know someone who can help.

YMMV, but I was too horny to actually make use of my superior fluid intelligence in my 20s, so I’m content with the tradeoff here.

Strongly disagree.

Crystallized intelligence lets me see analogies and relations between disparate domains, abstract patterns that repeat everywhere, broadening my vision from a blinkered must-finish-this-task to a broader what-the-hell-is-this-world-I'm-in. I'm old enough to realise life is finite. Nothing satisfies like understanding.

Emotional intelligence lets me actually behave more like what I know a sane person should behave like. It lets me see I don't have to act on every passing whim and fancy, which are more like external noise than something of an essential expression from my inner self (which is a culturally-instigated fantasy). It lets me see how I'm connected to everyone else and everything in the world. Why I shouldn't stuff my own pockets at everyone else's expense. Why making other people unhappy ultimately makes myself unhappy. It wouldn't have been that hard to spot if I hadn't been caught up with fluid intelligence feats of strength.

These are the real rewards of middle age, not anyone's consolation prizes.

That said, I respect your right to disagree. But I feel this particular way.

Don't knock crystallized intelligence.

In my 20s, I could learn a programming language in a weekend by reading a book. I could write code fast. I could figure out bugs. I felt so fast and so smart.

In my 40s and 50s, I looked back at that guy with some amusement. Sure, I didn't type as fast. But I spent a lot less time debugging because I wrote it right the first time, because I could just see what the right thing do to was. Net result was that I produced working code in less time. 48 might have been my peak year.

The paper actually argues we peak in our 50s.

”Across both model weightings, humans appear to reach their peak in cognitive–personality functioning between the ages of 55 and 60.”

Really? What did you achieve in those times of high fluid low emotional intelligence?

I played a whole lot of video games myself. These days my hobbies are way more productive and i feel much better focus.

> Yet, human achievement in domains such as career success tends to peak much later, typically between the ages of 55 and 60. This discrepancy may reflect the fact that, while fluid intelligence may decline with age, other dimensions improve (e.g., crystallized intelligence, emotional intelligence).

Isn't it about accumulated human capital (aka social networks) and experience more than anything else?

Reading the abstract it would seem a good reason for positions in government like the President to be restricted to ages 40-65.
