Yep. In the actual psychology research literature, since 1943 there's been research on "Fluid and crystallized intelligence":
https://en.wikipedia.org/wiki/Fluid_and_crystallized_intelligence
According to that, the young use "fluid intelligence", they do reasoning "that depend only minimally on prior learning".
As person ages, naturally they are capable of using more and more learning in their reasoning; they are able to use more "Crystallized intelligence".
'It reflects the effects of experience and acculturation. Horn notes that crystallized ability is a "precipitate out of experience,"'
Both kinds have advantages. More modern research shows that use of Fluid intelligence by the young is much faster, by milliseconds, than Crystallized intelligence.
But Crystallized intelligence is more often accurate.
There are simply tradeoffs, not that age makes either group inherently better or worse than the other. It depends on the task at hand.
