I answered a question on this site yesterday where in my answer, I alluded to a problem with cultural bias in early modern Western linguistics.
I tried my best search engine fu to come up with a good link to explain this in more detail, but I failed.
A particular anecdote I mentioned in a comment would be nice to have covered; I recall reading that the French Academy set out in earnest to scientifically establish that French was an optimal language for science. I probably misremember the details, but this is a good illustration of the type of phenomenon which was fairly prevalent in the emerging field of linguistics in Europe, probably even before the proper rise of what we today call modern linguistics in the 19th century.
Ideally, I would like a pointer to an accessible and popular treatment of this cultural bias in linguistics and its manifestations, suitable for giving someone who may be unaware of this tendency in our culture and perhaps in themselves.
Allow me to quote a passage from my answer:
... early linguists had an embarrassing tendency to postulate superiority of their own language, in what now, with modern eyes, can only be characterized as an inexcusable naïvety about cultural bias and perhaps even xenophobia. Any claim that your language in particular is somehow remarkable should be examined with the utmost prejudice.
How can this be exemplified and explained in more detail? Specifically the application of ostensibly scientific ideas about language to reaffirm a chauvinistic agenda.
(Or am I wrong, and biased?)
