99% of them are far from you physically. If you weren’t personally affected it probably doesn’t matter to you.

I was unlucky and lost 3 grandparents between my wife and I. Matters more to me probably.

I doubt that they're disproportionately far from my physically.

I am really aiming for density here. I don’t think it’s weird (or debatable) that humans don’t care as much about other humans that are far away. They care about ones that are closer.

The thing is lack of density was sufficient to trigger this lack of care. Kind of interesting.
