Take, for example, sound in space. A human being with a giraffe head would be weird, as you say. It's not something we see everyday.
But we do hear sounds every day. And we're accustomed to machines and explosions making loud noises. The silence of outer space is completely outside our experience.
Intellectually, we may understand that there is no sound in space. But for most people, an explosion that does not make a loud 'bang' would be like a human being with a giraffe head: not just weird, but distracting.
Interesting point. Since tv and films are such an integrated part of life for most people in the 'modern world' there is a feedback here as well. If something is shown over and over in film and on tv, it becomes part of what is considered normal or conforming to intuition.
Not all the bad science falls in the category of 'bad science conforming to intuition better than good science'. What about the endless nonsense ascribed to dna/genetic sciences or the effects of radiation? I don't think there is any daily intuition on these subjects at all, apart from what we get fed by pop culture.
This also raises an interesting question about just what exactly would be 'realistic'. Realistic, from whose perspective? From what's perspective?
Unless the camera is carried by one of the characters in the movie, the perspective is usually from an external third person's point of view. Regarding this person to be part of the depicted reality leads to many problems. Why do other characters not notice him, why does this character constantly hear music in the background, etc. So it's safe to say that the perspective from which we're viewing the events is completely external, even if we would be able to feed the images and sounds directly into our brain without needing the help of a tv. But whatever our point of view is, if the events unfolding before our eyes are supposed to take place in the real world, then they will follow nature's lead. In the case of sound in space you argued successfully that based on one's point of view you might hear sounds (in which case it is also not 'bad science'), but for most other 'science problems' I don't see how changing your point of view might solve them. If something doesn't explode then it doesn't, no matter under which angle you look at it.
I'm starting to feel that I'm arguing too much in favour of rigorous adherence to science fact in fiction, which is absolutely not my goal. But the situation right now is too unbalanced I fear, in the wrong direction. And I'm trying to understand why this is. If there's anything else going on here than scientifically illiterate writer's not willing, wanting, or able to spend time and effort to research how things would actually work.
