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.
Just flaunting my ignorance of biology here.
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.
