So I was on a thread on /tg/ about geographical worldbuilding and feel this question is also appropriate to ask here, just extrapolate it to all dimensions of fictional believability and realism beyond geography, it can be easily applied as far as the psychology and behavior of characters. I'm ESL so I'm sorry in advance if it's hard to understand my point:

How much effort do you guys put into creating geography that makes sense? It's the whole scifi issue where you may go through tons of effort trying to make things be logical but when it comes down to it, if something in the realm of speculative fiction is sufficiently analyzed from a scientific point of view, it will always be exposed as an unrealistic crock of shit(even if it takes 100 years to dismantle it in light of further discoveries).

Do you just make it believable enough with common sense logic to avoid the more obvious mistakes(like don't put a scorching desert next to frozen tundra) so non-experts like you and other common folk cant immediately point out the flaws and question its logic?
Like for example, in those medical dramas, most people can enjoy them just fine without overthinking it but if actual doctors try to watch them, no matter how hard they try to accept its just dramatized fiction and do their best to suspend their disbelief, they will still be involuntarily taken out of it, constantly cringing and rolling their eyes at the ridiculous inaccuracies.

Or can we just accept its all pure escapist nonsensical schlock where anything goes and embrace that things are the way they are for maximum entertainment? Because if that's the case, why do we see everyone holding back and making futile attempts at making things adhere to the constraints of realism? If its really just about keeping it believable enough with things that don't blatantly challenge the basic understanding of laymen, doesn't that mean ignorance is an essential part of what allows us to enjoy speculative world building? Because again, if we can simply 100% accept it just comes down to set up whatever accomplishes maximum entertainment and turning some of our brain off there's a whole lot of unnecessary and even counterproductive effort in orchestrating events that feel grounded.
