Neue Forschungsergebnisse zeigen, dass Menschen ihren allgemeinen mentalen und emotionalen Höhepunkt oft etwa im Alter von 60 Jahren erreichen, nicht in ihren Zwanzigern. Während das schnelle Denken mit zunehmendem Alter nachlässt, verbessern sich Erfahrung, Urteilsvermögen und emotionale Ausgeglichenheit in der Lebensmitte immer weiter

As your youth fades further into the past, you may start to fear growing older.

But research my colleague and I have recently published in the journal Intelligence shows there’s also very good reason to be excited: for many of us, overall psychological functioning actually peaks between ages 55 and 60.

And knowing this highlights why people in this age range may be at their best for complex problem-solving and leadership in the workforce.

Different types of peaks
There’s plenty of research showing humans reach their physical peak in their mid-twenties to early thirties.

A large body of research also shows that people’s raw intellectual abilities – that is, their capacity to reason, remember and process information quickly – typically starts to decline from the mid-twenties onwards.

This pattern is reflected in the real world. Athletes tend to reach their career peak before 30. Mathematicians often make their most significant contributions by their mid-thirties. Chess champions are rarely at the top of their game after 40.

Yet when we look beyond raw processing power, a different picture emerges.

From reasoning to emotional stability
In our study, we focused on well-established psychological traits beyond reasoning ability that can be measured accurately, represent enduring characteristics rather than temporary states, have well-documented age trajectories, and are known to predict real-world performance.

Our search identified 16 psychological dimensions that met these criteria.

These included core cognitive abilities such as reasoning, memory span, processing speed, knowledge and emotional intelligence. They also included the so-called “big five” personality traits – extraversion, emotional stability, conscientiousness, openness to experience, and agreeableness.

We compiled existing large-scale studies examining the 16 dimensions we identified. By standardising these studies to a common scale, we were able to make direct comparisons and map how each trait evolves across the lifespan.

Peaking later in life
Several of the traits we measured reach their peak much later in life. For example, conscientiousness peaked around age 65. Emotional stability peaked around age 75.

Less commonly discussed dimensions, such as moral reasoning, also appear to peak in older adulthood. And the capacity to resist cognitive biases – mental shortcuts that can lead us to make irrational or less accurate decisions – may continue improving well into the 70s and even 80s.

When we combined the age-related trajectories of all 16 dimensions into a theoretically and empirically informed weighted index, a striking pattern emerged.

Overall mental functioning peaked between ages 55 and 60, before beginning to decline from around 65. That decline became more pronounced after age 75, suggesting that later-life reductions in functioning can accelerate once they begin.

That’s why the world would be a better place if we lived 500 years or more, we die before achieving the tutorial

Tell that to this job market!

35 was my mental peak from a pure performance x experience perspective. Ie the last year my brain still went to 100% in times of need 

Every year since then I hope I’ve gained enough experience to offset the cognitive decline:)
