A major new meta-analysis (287 independent experiments, more than 21,000 participants, spanning 1990–2021) shows that adults today perform better on concentration tasks than previous generations.
Key findings:
-
Adults score significantly higher on concentration performance (CP) in the d2 Test across 31 years. Our attention capacity hasn’t declined — it has strengthened.
-
There is no evidence of worsening attention in either children or adults. No decline. If anything, stability or improvement.
-
The test setting is strictly controlled: clear tasks, no distractions, high predictability.
When the conditions are simple, structured, and free from noise, adults perform better today than they did decades ago.
Important:
The study examines capacity, not context.
It only tells us that when we get clarity and calm, we perform better than people did in 1990.
Daily distractions may disrupt our attention in the moment, but they do not weaken our underlying capacity.
What about children?
Children do not show decline — but they also do not show the same improvement as adults.
Their capacity is stable, but their test-taking style has shifted: faster, with more errors. Not because they “can less,” but because their approach has become more impulsive.
In other words:
Our ability to focus has not decreased.
It has actually gotten stronger.
The problem isn’t our attention.
The problem is the environments we place it in.
Attention is only an advantage when it’s directed at the right things.
Because these studies are experimental, they highlight the gap between capacity and everyday reality:
In daily life, it makes sense to use attention deliberately — to choose what deserves your focus, and what doesn’t.
In a time where everyone is talking about distraction, it’s worth remembering:
The ability is intact. The task is to use it wisely.
