What do you think someone studies in college to become an aleithometrist? It seems in TSC that Lyra is studying history and Hannah describes herself as an "historian of ideas." However, given that symbology is not really a robust and flourishing field, it seems to me that any number of backgrounds would be helpful for reading the Aleithometer - philosophy, anthropology, and literature are some others that come to mind.
They'd all probably be philosophical studies or linguistics related areas in my opinion too. But I don't think the alethiometrists need to have a specific field of study, rather than actually enrolling in alethiometer studies specifically.
Technically, one needs to study the instrument itself, but having a background base in linguistic or even philosophy, like Hannah did, for example, definitely helps because it correlates to the whole concept of reading, which is understanding symbols.
I definitely think a majority of readers would be humanities students, probably, but no in a mandatory way.
