Basically, if the author is saying,
I know this doesn't really
work, but I wanted to see what happens if I work off the premise that it could
maybe work, come and join me in this little experiment, I'm game. But if their attitude is one of trying to show off, or else you can tell that they just didn't bother to research, I'm seething all the way through. Unfortunately, I have to finish books once I started them, so there's a lot of seething going on, but at the same time I'm also taking mental notes on how not to write for myself.
Brit here, and they definitely teach American geography in schools here, though not in huge detail. I think the sense of scale is lost to a lot of kids.
And you'd be horrified by the amount of Americans I've had conversations with who think England and Britain are the same place, or think that Scotland or the UK are an American state. (
Obligatory Mitt Romney nod.)
Not just Americans. I've had Poles conveniently lump the entire island together as "England" because "it's the way we speak." Mind you, this was one particular group of people, so I'm not speaking for the entire nation, but they were pretty well educated and well-traveled. And they had all been to the UK. A lot of them didn't even realize that there was such a thing as Northern Ireland and the Republic of Ireland.
Considering all the American places that were named after towns in Europe and even some countries in America (I'm guessing also Canada, but I only spent less than a year there when I was a kid, so can't talk with any authority where that's concerned), I can understand why you'd get that immediate reaction of "which state is that place in?" We used to live in Bayonne, NJ for a while, and every time you mentioned Bayonne to my dad after that, he'd ask if you meant the town in NJ or the one in France. And to say he was well-traveled would be a gross understatement. But I can also understand how people feel put out if you get their hometown mixed up with something else that's more or less alien to them.
Like you said, the sense of scale is impossible to imagine if you haven't lived there. Until the age of nineteen, I spent half my time in North America and the other half in Europe. What got me were the prejudices and preconceived notions a lot of the teachers had about the U.S. at the schools I ended up in, the one where they asked me how come I couldn't play basketball when everyone played basketball in America was the nicest.
As an interesting aside, when I was in Germany, Romania was the country a lot of fellow students came from as they were ethnic Germans there. In the English-speaking countries, Romania was always associated with Dracula (no one at the school I went to in Germany even mentioned this, though I'm sure in other parts of Germany it would have gotten mentioned).
When I was at university in England, a lot of the students there knew their facts when it came to France, Germany, Spain, and the countries they came from and had friends in. In our group, no one really knew anything about Eastern Europe, so I'd get a lot of whispered "where is that place again" comments when some places in Hungary were mentioned, or even Bulgaria. And this was an international group of students. Someone once pointed out to us that sure we as Europeans know about all the European countries and their capitals, but do we have any idea how many countries there are in Africa and what their capitals are? That really got me thinking. In France (my native country so to speak), I went to a travel agent who dealt with international students and was located in a student district to book a flight to Budapest, Hungary (my specifications). When the travel agent printed it all out, I saw that she'd booked the ticket for Bucharest.
And to cap it all off, when a German friend told me she'd travel to Hungary with me "only if it's by the Black Sea", polyglot, multilingual, cross-cultural yours truly marched straight into the nearest travel agency announcing, "I'd like to book a flight to the Black Sea in Hungary, please." I realized later it was April Fools', but I still felt stupid as anything.
One case where the whole issue of sloppy research was really well spoofed was the episode in The Big Bang Theory (I think it was Season 2) when they enter the Physics Bowl against Sheldon and his "team". One of Sheldon's teammates answers the question correctly, and then tells him that he was a physicist at "Leningrad Polytechnica" before adding, "go Polar Bears." I heard from a lot of Finnish friends that they kept getting asked if they had polar bears in Finland, and I'm guessing it's the same for other places more or less close to the Arctic Circle, so bringing that into the show was a stroke of genius to me.
It depends, really. When I see something that is as factually wrong as the adoption age limit you cited, I tend to assume (at first) the character is lying for their own purposes. If that proves not to be the case, and it was indeed a research error, I become highly annoyed. I won't read that author again.
This.
There is a historical fiction series I like that is very nicely done, but I always giggle when I get to one scene. It involves a kitchen, and it is remarked several times that the cook keeps a *wet* cloth for handling hot kettles.
Maybe the cook had super powers and wanted to be sure everyone was aware of that. Or else Cook was into (subtle) S&M by stating,
look at how tough I am, I can pick up a hot kettle with a wet cloth.
I sometimes get completely put off by inaccurate information too, but my big no-no is having and MC or another major character speak another language than English, and then have that other language be persistently wrong

It shouldn't be all that difficult to get someone to check the French/Spanish/German or whatever other language (that often is not necessary for the plot) to at least have it correct, no?
I so agree! It's getting to the point where I'm already looking for the mistakes, because I know they'll be there. And in most cases, I get the feeling that they're just sticking it in there to show off. I get that some phrases you just can't translate, and they really work better in the original. For some reason I'm thinking of Yiddish terms. But then, especially in the English-speaking world, we've been around enough Yiddish terms to be familiar with them. It's also true that people shift in and out of languages frequently. My brother and I used to do it a lot, because of the way we grew up, and I know a lot of people who do. But do it because it's natural, not because you want to show off how much you know (and then end up looking stupid). If you really want to convey what you know of the language, either write in it or else think in it while you're writing in English or whatever language you're writing in. You'll adapt the flow and feel automatically. There was one book about Hungary that really made me want to throw the whole thing across the room.
It depends on what the particular issue is and how much I otherwise enjoy the book.
On page 5 or so of FIFTY SHADES OF GREY, the main character gets in her car and drives from Vancouver, WA toward Portland to get to Seattle. She also gets to Seattle in under an hour. The only thing I can conclude is that the author didn't realize the United States and Canada are separate countries and mistook Vancouver, B.C. for Vancouver, WA. But surely, they teach North American geography in England the same way they teach European geography in the U.S.? I mean, even with the whole Great Britain thing, I think most Americans understand that Scotland is not England and vice versa...
But I was looking for a reason to fling that book against the wall.
I always got the feeling with 50 Shades that she just wanted to see how far she could go, and how much she could get away with. Still not (entirely) convinced the whole thing isn't some kind of study of how much humanity can accept / buy before it starts yelling "foul." Haven't read it though, because from what I've picked up on so far, the whole thing reeks of arrogance to me (let's see how we can fool others, let's see how little research I can get away with, etc) and so not planning on it, so I'll bow out now.

Although, if I'm spouting off on it, I really should read it.
I think it's interesting to watch trends in what monsters are popular and ask what it says about the collective fears of society. Zombies in their "modern" form seem, to me, to represent both the fear of global pandemics and the fear of the rise in extremist forms of fundamentalism (i.e. group-think mindless hordes that want to eat your brains and make you just like them).
There was a part in one of the Burke novels by Andrew Vachss where he went to see a Voodoo priestess, and she explained to him how he was one of the living dead, because he was dead inside from being emotionless. I remember having this huge "aha" moment when I read that.
I loved the entire series, and for a while I was a huge fan (still love the books, but looked into other things). There was a moment though where he mentioned something about people and dinosaurs living at the same time. I tried to look for a way that he was doing it to make a point, but I remember thinking,
really? Why did you have to do that? I had so much respect for you until now. I think I got over it, by using a similar situation in my WIP, but it took a while. And, to the best of my knowledge, that's the only case where I was able to forgive (but not forget), and he definitely dropped a few notches on my "hero" scale.
Experts of all varieties are very willing to help writers.
See if there's someone who was there at the time who you could talk with.
Is there someone near the site you're interested in who would be willing to be interviewed, either on the phone or by mail?
Is there a local historical society?
Google is nowhere close to being enough.
I usually google it first, then go to Wikipedia. In both cases it's to get a general idea. Then I start harassing the experts. A lot of them are more than willing to help you out, like you said. Funny thing though is, I've had people refer me to the internet as though that were the ultimate authority, ironically, usually not the experts but the people I needed to ask about the experts. Much as I love and respect the internet, I still prefer talking to people and seeing the places (which isn't always possible). But it seems to be a dying trend these days. I sometimes set assignments for my students that force them to ask people. It's good for their language skills, but I'm also hoping that it will make research more interesting so they pick it up again.
