Hedging in Popular Scientific Articles on Medicine

Introduction: The aim of this study is to investigate the process of rewriting medical research papers for the lay public. The latest findings of medical research often appear in the popular media. It is interesting to see what happens to a scientific text when it is transmitted to a new audience. Hedging is usually interpreted as a characteristic feature of scientific discourse. This study focuses on hedging, which also tends to be applied in popularized articles in the field of medicine.
Material and method: Five medical research articles on prenatal vitamins and their online popularizations were examined by means of a text analyzing software, focusing on lexical items considered as hedges. The frequency and the overall percentage of hedging devices with respect to the total number of words were recorded in the five popularizations.
Results: The results of the present study suggest that the linguistic strategy of hedging is applied in popular articles. Approximators, auxiliaries, epistemic verbs and adverbs expressing tentativeness, possibility and politeness were used in the corpus. The overall percentage of the lexical items commonly regarded as hedges, with respect to the total number of words, was 1-2.2% in the five articles. The writers also use linguistic techniques that can be interpreted as attribution shields. These defense tools convey the meaning that it is the researcher, rather than the writer, who is responsible for the truth of the information.
Conclusions: Hedging as a means of uncertainty and negative politeness technique is used in the popularizations analyzed. The present study should be extended to investigate tendencies in popularization of scientific information.
