Even though textbooks sometimes portray academic writing as a fairly unified concept and craft, scratching on the surface reveals a more multifaceted world. In this subsection, a number of differences between different disciplines will be accounted for.

The use of first person pronouns (I and we) in academic writing
One of the more commonly mentioned trademarks of academic texts is the supposedly impersonal style that is used. Impersonal style is often correlated with a complete absence of personal pronouns, in particular the first person singular or plural pronouns I and we.
It is not uncommon for textbook writers, or star scientists (see the quote by Albert Einstein below, for a case in point), to advise against the use of personal pronouns. This is probably so because the absence of pronouns like I or we is thought to give the impression of research being more objective, credible, and free from individual opinion.
However, as empirical studies investigating this indicate, there is in fact quite a bit of variation across disciplines, when it comes to the use of the first person singular or plural personal pronouns.
In a study of 240 research articles from eight different disciplines (mechanical engineering, electrical engineering, marketing, philosophy, sociology, applied linguistics, physics, and microbiology), where the articles were analysed for their potential use of the pronoun forms I, me, my, we, us, and our (the subject, object and possessive forms), Hyland (2001) found that the average number of pronouns referring to the authors of the texts was much higher in articles from the soft fields (marketing, philosophy, sociology, and applied linguistics) than in the hard fields (engineering, physics and microbiology).

There was also a difference in terms of which pronoun forms were used in the different disciplines. There were no instances of the subject form of the first person singular personal pronoun I in the articles from the hard sciences. In the articles taken from the soft sciences, however, there were on average around 12 cases per paper.
The average number of instances of the subject form of the first person plural personal pronoun we in the hard science articles was 8.7, compared to 10.9 in the soft science articles. Articles from mechanical engineering had only on average around 2 instances of we, whereas articles from marketing had around 20.
