I don't know if that is a psychological quirk - it seems pretty rational to me. We are more affected by events that happen close to us than those that happen far away, so instinctively finding local events more interesting than distant ones seems like what I'd expect[0].
[0] Not that my expectation has any weight, I have close to zero knowledge of psychology.
Unless you are in a highly urban area, most Wiki articles will be about _places_ and sometimes _events at the places_, but usually not _events_ themselves.
For things that affect people, I think the impact of the recency axis is significantly larger than the one of the geographical axis. e.g. I feel the effects of the Iran war in my daily consumer prices in my daily life. I don't feel the effects of a famous person being born two doors down from my place 200 years ago in my daily live.
Of course highly local things, like e.g. local politics are also felt, but those are also barely reflected in Wikipedia articles.
Mhh i wonder how this would have evolved, since, you know, for 99.99% of time, humans didn't really get any information other than from their immediate proximity. And if they did (e.g. earthquake), it was very much relevant and should affect them.
Just flaunting my ignorance of biology here.
I'm at least a tiny bit less ignorant on biology than psychology. I don't think this is the kind of thing that does evolve.
Normally more general capacities than that evolve. We've evolved the ability to learn and adapt, and that's what we're using to create these heuristics. But I don't people evolve into individual beliefs/attitudes in that way.
I mean, it's the brain, not the world around it. Our brains haven't really evolved much while civilization and technology have been growthmaxxing. Same reason why certain social media posts can trigger a physical, emotional reaction, even though for 99.99% of the time there were no cellphones or social media.
