I just went swimming, my second time swimming in the sea this month, after nearly two years without getting to. It was excellent. You don’t know how much I’ve desperately missed the sea.
We were talking about orienteering on the drive home, however, because we drove past a place you used to be able to do that, at least a decade or so ago, I’m not sure if they still do it, and we were talking about maps and being able to read maps and having a decent sense of direction, and it reminded me …
One of the moments I’ll never forget in college was a class on how to read the Ordnance Survey maps (OS maps for short, really excellent maps of Ireland with a LOT of detail and information), and the lecturer had put up a magnified section of the map on the projector and was asking us questions about it. One of the questions was a grid reference between two contour lines, and he was asking what height range the reference was in. One of the lines was numbered, but the height of the other line was off the edge of the magnified section of map, so we only knew one of the line heights for definite. So basically, if you’re just using the lines, it’s plus-or-minus 100ft and we don’t know which. He asked for the height range, and the first person he asked guessed wrong. Then he asked me, and I gave the right range, and he asked how I knew. And I said that there was a spot height on the other side of the line from our grid reference that was higher, so we were clearly on the lower side of the range, plus we were on the side of the line with the river, so that also placed it lower.
And another girl in the class, looking at me, asked in this sort of shocked tone: “Wait, are we allowed to do that?”
Are we allowed to use other environmental information to figure out where on the map we are. It always struck me as such a weird question. Like she thought it was cheating, that because the question was based on the contour lines that we could only use them to figure out where we were, even when half that information was missing on the section of map we had.
It says something, I think, about the way we’re taught to look at problems and information, that we look at them in this really artificial and isolated way. There was all sorts of information around the lines on the map that could be used to help figure out what side of them we were on, and that’s actually the point of reading a map, to help yourself figure out where you are using whatever information you have, but she just … apparently felt like that was almost cheating? That because the question was asking in a class setting and it was asked about a particular feature, that you could only use that feature to answer it, even if, in this particular instance, that wasn’t actually possible.
I don’t know, that moment always felt really strange and weird to me, and in hindsight I think it does highlight a sort of … artificiality about how we’re taught to use information sometimes? How school sort of breeds in this instinctive and honestly arbitrary notion of what sort of information we’re allowed to use, and how things like open-book learning and contextual and environmental clues are, if not forbidden, at least apparently frowned upon. And I know there are circumstances where the environment can bias interpretation of information, and that is the sort of thing where there are pros and cons depending on the situation, but it just …
It stuck with me. The sort of shock she had. That the question was phrased, not as ‘wait, should we do that’ but as ‘wait, are we allowed to do that’. Allowed. Not ‘is that method a good method to use, will it affect the information somehow’ but ‘is that a method we’re allowed to use, will we get punished for relying on information we weren’t specifically told was permitted’.
I’m not sure how to fully articulate why that moment stuck with me so much. In the moment, it just felt strange and weird, that way when you just bump into a way of thinking that just strikes you as weird because it didn’t occur to you that that could even be a question, but …
In hindsight I think it really does say something about the ways we’re taught to think and view information, both finding it and using it.
IDK, it was just a weird moment, and it really stuck with me
