This article probes into Trumpism using McLuhan’s idea of figure/ground analysis. To make visible the hidden ground behind a salient figure (or figures), the dichotomy of instrumental and environmental approaches to media effects is introduced. The widely used instrumental approach
is rooted in the long-standing Lasswellian tradition of communication studies (‘who says what, in which channel, to whom, with what effect?’). The instrumental explanations of Trumpism are unavoidably reductionist, as they focus on figures and, therefore, overemphasize rationality
and agency in media use. On the contrary, the environmental approach focuses on hidden ground and explores what environmental forces originate from new media’s proliferation and how these forces reshape habitat and inhabitants. To apply this view, the article examines the environmental
factors within the news industry and social media that are favourable to Trumpism: the commodification of Trump by the media, the morphological conflict between broadcasting and engaging modes of agenda-setting, the built-in polarization of social media and others.
