Gonna pull out my hair splitting razors for a moment…
OP didn’t say more intelligent, they said smarter.
Can one get smarter? Does “smart” conceptually include the quanity of acquired information? Does the quality of thought impact the ability to acquire new information? Does smart include the concept applying knowledge appropriately? Is the ability to do that informed by the quality of thought?
We might have different definitions for a lot of these words, but I think I gotta say “yes” to all of them.
I’m not this guy so I can only guess their experience, but the more time they’re able to spend in a mental state that maximizes the quality of their thought processes, I would expect it would help them learn new things and more effectively apply that knowledge. I’m contented to say that counts as smart.
So ya: More think good make more smarter that guy.
You jest but that’s roughly the story of the “discovery” of Machu Picchu
