National identity and academic writing

It is very common for authors to use first person pronouns and adopt national identify in their paper. There are several reasons why they do so, first because for some people it is quite natural to speak as such so they carry it across to their writing, second, due to the subject topic and context, they often assume clarity when saying “in our country”, another reason is because it can save some word counts. Examples of words and terms with national identity include: in our country, our citizens, we, national statistics, nationally, our people, our GDP etc. However, will the reader necessarily be from that country or know the country being referred to? Professional academic writers should not make that assumption and should refer directly and specifically to whatever being discussed, for instance, a country, people, civilization, ethnic group, or a linguistic group.
