TL;DR: it depends; travelogues need detailed descriptions; otherwise, prefer minimal style; must consider the reader; less descriptions == more assumptions;
It depends on what I write and for whom I write.
I enjoy reading detailed travelogues, both of places I have lived in and places I have never visited. Travel literature lives on detailed descriptions. Those descriptions tell you as much about the writer describing said reason as they tell you about the region being traveled.
Although I do not plan on ever publishing them, I wrote a few travelogues back in the day.
There are other kinds of books that live on their setting rather than their plot. But I generally prefer writing the other kinds:
I enjoy writing in such a way that not a word is extra, unnecessary.
This comes with having
certain expectations of the reader:
- Do the readers share my cultural knowledge? Do they know what a car looks like? Do they know what a typical human looks like? What about the sky, the earth, and the sun?
- Do they possess similar senses and a similar manner of processing their sensual input? Can they see? Can they see colors? Do they mostly rely on their vision (as opposed to, i.e., bats who use sound) to perceive the world?
- How do they move? What is their relationship to spacetime?
The issue is mostly that first point. Since my target audience are (presumably) humans from planet earth living in the 21st century with access to the internet, our common understanding is great enough that if I were to write,
"The truck sped down the road and hit the cat at full speed,"
they would understand that the cat was most likely dead or, perhaps, isekai'ed. They would not need to know that the truck had four wheels and that a cat is a mammal, nor would they wonder what a road could be. Unless they were aphantasiac, their mind would create an image of a "generic" truck hitting a "generic" cat. These genericism would vary considerably, however.
If I were to translate the sentence for a person from 2000 BCE Greece, I would need to describe "cat" and "truck", if not "sped down" and "hit at full speed". They would have seen few things move at and even fewer things collide at such speeds.
This was an extreme example, but the process and considerations remain roughly the same for all types of audiences.
