Thinking of cosmic distance scales and ways of mentally dealing with them.
I’ve met a similar effect in an entirely mundane context: being a treasurer for a convention.
Some people in British SF fandom are rich, some are poor. For some of them an expenditure of twenty pounds needs serious consideration and the few hundred for the hotel at a big convention may mean saving up all year.
But for some and only some, and not particularly the poorer ones, the idea of being responsible (not liable, but responsible) for some tens of thousands of pounds of convention funds is clearly terrifying. And for others, it’s not, because it’s just like single digits of pounds, you just put some more zeroes on the end.
