While Louis Pasteur’s germ theory functions as one of the foundational concepts of modern medicine, resistance to COVID-19 prevention measures reveal a rejection not just of government mandates, but of germ theory as well. Therefore, this article seeks to trace the rhetorical linear of rejections of germ theory denialism through an examination of primary and secondary texts from Pasteur’s contemporaries, through the development of chiropractic, and into the COVID-19 pandemic. The author finds that the denial of viruses offers a peculiar form of biorhetoric that invokes absence and invisibility, rather than presence, as rhetorical grounds for rejecting public health directives.

Recent work across disciplines has examined the current post-truth climate and various types of information disorders which have permeated the internet. Scholars have made significant progress in defining and theorizing information literacy and its various aspects, as well as in designing programs to help students acquire the relevant skills for evaluating information. Nevertheless, further exploration is needed, for example to understand the roles of criteria in information evaluation. The present study draws on scholarship in discourse and rhetoric studies to suggest how discursive strategies, a key concept in these convergent areas, can inform approaches to information evaluation. To illustrate this improved approach, this study explores the case of a recent piece of fake news that involves both text and image and has circulated widely as a digital flyer on social media.

In this paper, we explore the gendered aspects of scientific controversy in the digital age. This project makes use of Leah Ceccarelli’s seminal work on manufactured scientific controversy by considering its implications for the discourse on GMOs and food additives published on digital food and lifestyle blogs. We perform a discourse analysis of several blogs to look at the ways that gendered online discourse and performance influences modern anti-science rhetoric, particularly that which emanates from the sphere colloquially known as crunchy living. We look at the ways the intimate and personal feminine style of digital platforms offer experiential knowledge as a substitute for science. In the current political climate of alternative facts and fake news, this study leads to broader implications about the impact of gendered discourse on the assessment of credibility in online sources.
