Now, that co-incidence can be put down to Robert being a common first name and Drake is not so rare either. However, there are much stranger co-incidences out there. Just a quick search on Google brought up dozens on the first page, like the falling baby in the 1930's saved by the same man twice, or twins separated at birth who marry the same kind of woman, sometimes with the same name, and get a similar job. In the real world, we accept these coincidences and just look for explanations, like the baby fell from the same balcony where it was placed at the same time every day and that man happened to be walking home at the same time every day, so him being the one to be in the right place at the right time both times is within the realms of possibility. And with twins, there is the whole, nature vs nurture debate.
There are also all sorts of other weird and wonderful things that go on in this world upon which oracles such as Ripley's Believe it Or Not base their whole raison d'etre. And because there is evidence (some of the time), we believe what we're being told.
However, the writer of fiction has none of these luxuries. There will never be proof of what they are telling their reader, since it is, by it's very nature, from the imagination. So, we have to suspend our reader's disbelief and convince them of the reality we are presenting them with. We have to establish a contract with our reader, help them understand the rules of our created world and we have to persuade them that world could exist, even if only on the page.
Fantasy has an advantage over other types of fiction, because often there is the supernatural, or sorcery involved, which can be shaped any way the writer likes, because it's magic. However, Science Fiction, and it's cousin, Steam Punk have a much bigger challenge, because everything is much more grounded in the realm of physical, biological and natural laws. If a writer wants to create the fantastical in these arenas, their readers expect much more precision and reference to these laws. Someone can't just fly up into the air because they whisper a few words of magic, there has to be a contraption, be it natural, or mechanical, or technological that allows them to accomplish this flight and that contraption has to be convincing.
OK, so some sci-fi didn't bother with obeying rules, like Space 1999, that seemed content to ignore the effect that no longer being in orbit of the Earth would have on the moon, and indeed, vice versa. And, one of the things that always makes sci-fi fans laugh is the big explosion sound that happens whenever something blows up in space on TV. Neither of these anomalies stop us enjoying the shows this happens in, but it does allow purists to have a good chortle ;P.
That doesn't mean I, as a writer, feel free to throw anything into my fantasy work. I want my universes to be coherent in themselves, their own internal rules should be consistent and make sense. That's why Tash, my sister and co-writer of The Haward Mysteries, spent a long time working on the rules of magic that exist within that universe before we started writing. And we also collect the rules we generate as we go along in a wiki, so that we can refer back to them.
So, depending on your genre, some ideas may take a lot more researching than others, but the basic tenet is to be consistent. Breaking your own world rules is a no-no (well unless it's a very clever plot device that shatters rules that characters thought were true, but turn out not to be, and that can take a lot of intricate planning and is not the type of thing I'm talking about here). Breaking rules, without realising/remembering, is a sure way to annoy readers/watchers and throw them out of your universe, so a story bible, I find, is essential. It has more than just world rules in it, it can have character details, locations, objects, all sorts of things, but I always have one, either informally in notes in Scrivener, or more formally like the wiki I share with my sister for Haward Mysteries.
If you're a writer, how do you keep your world rules straight?
If you're not, do you find it a annoying when writers, or TV shows forget their own rules?
