The present study compared and contrasted the frequency of use of hedging devices used in the research articles of three fields of Humanities, Basic Sciences and Agriculture and three sub-fields within each field (i.e. Law, Persian literature and TEFL within Humanities; Biotechnology, Soil Sciences and Horticulture within Agriculture; and Biology, Applied Chemistry and Geology within Basic Sciences). In so doing, 180 research articles, 20 from each sub-field, were selected and analyzed based on Salager- Meyer’s (1994) taxonomy of hedging. The results of the chi-square analyses revealed, regarding the frequency of use and type of hedging devices, there were significant differences among: a) the three fields of Humanities, Basic Sciences and Agriculture; b) the sub-fields of Humanities, Basic Sciences and Agriculture.
