For me, it depends on what point of lore we're dealing with.Â
When the game hands me a hard "This is how it is, no exceptions", I take it as it is. Like Purebred Garleans being genetically unable to use aether. Devs have specifically stated this to be, so that's just how it is.
When it's something that could be taken as ambiguous, for example like exactly how rare the Echo is, I look at various things. Is there evidence that suggests one thing? Is there evidence that suggests something different? What is the opinions of others, and how solid is their reasoning? From there I'll make a theory and run with it, though some things (like how rare the Echo is), I'll keep to myself because I know not everyone will accept it. It's a judgement call, really.
Then there's other things where my line of logic goes "This is a minor thing, it makes sense when compared to the Real-World equivalents of the setting, and there is nothing in the game or from the Devs that say that this wouldn't exist, so until something is released that specifically says that this thing cannot exist, I'll RP it exists". Like coffee. While there is no icon in the game for coffee, the concept is benign enough that only the most strict and bitter lore-nazi's are going to pitch a fit over it. If in a later patch/expansion something pops up that says "Coffee is being introduced as a new import from X-region", then my characters have been drinking what amounts to be a coffee substitute all this time.
