Arguing with numbers in digital multimodal dialogue

Sumin Zhao & Chris Cummins

Abstract

Statistical data—death tolls, hospitalisation rates, vaccination rates, R-numbers—have played a prominent role in Covid-19 discourses. Numbers are foregrounded in government briefings and news reporting, shaping public debates on pandemic measures such as lockdowns and vaccinations. While statistics and numbers are often seen as “objective” and “factual”, they can nevertheless be exploited for rhetorical and argumentative effects (Cummins & Franke 2021). Presenting numbers in a particular way can potentially advance different and mutually irreconcilable narratives about a situation, in that a speaker/writer can select among the many truthful ways of describing reality with numerical data to produce a specific discursive effect. For instance, if the case rate increases from 1% to 2%, this can be described as either a 'doubling' or a '1% increase'. Our project sets out to understand how numbers have been used to promote and justify policy decisions and personal choices on social media during the global pandemic.

In this talk, we focus on numeric information presented in multimodal forms, including scientific graphs produced by researchers and those generated through visualisation applications such as Our World in Data and used by non-expert posters. Drawing on pragmatic theories of number meaning (Cummins & Franke 2021) and multimodal theories of social media (Zhao & Zappavigna, 2018) we will show that quantity information is selectively presented (even by objective and cooperative interlocutors) in Twitter debates on Covid. The selective nature of the visual data presentation is facilitated and enabled by the design of the visualization application. We argue that to protect ourselves from drawing erroneous conclusions, we need to understand the argumentative stance of the speaker. This applies to graphs as well as utterances. There are good reasons to think that typical hearers are highly skilled at inferring a speaker's argumentative stances based on very little information (e.g. how they package a graph in a tweet). We will close the talk by revisiting classic multimodal works on scientific and mathematical discourses (e.g. Bezemer & Kress, 2008, O’Halloran, 2008) and discuss how changing digital visualization technology and social media cultures will shape how we approach multimodal literacy in the age of big data.
