AbstractThe effectiveness of and its boundary conditions regarding fact–checking news exposure have significant normative and practical implications. While many of the prior studies have focused on the attitudinal consequences of fact–checking news delivered by neutral third parties such as fact–check organizations, relatively less is known as to the effect of fact–checking news delivered by partisan media. Based on the frameworks of motivated reasoning and the hostile‐media effect, we investigate the possibility of decoupling between attitudinal persuasion and perceptual backfire by fact–checking news by partisan media—that is, exposure to fact–checking news increases bias perception of such news yet nevertheless attitudinally persuades audiences. Based on a series of original experiments conducted in South Korea and in the United States, we find consistent support for our prediction, in that exposure to fact–checking news produces the corrective effects, yet at the same time perceived bias of the fact–checking news systematically varies as a function of the ideological slant of partisan media.

This study sheds new light on the relationship between emotion and engagement. Specifically, we investigate how the six discrete emotions that news visuals deliver, as well as the positiveness of news text, are associated with three engagement activities: sharing, commenting, and reacting. The findings show that users are less likely to share or comment on news posts that convey positive emotions, although they tend to react to such news frequently. The most prominent kind of emotion associated with user engagement activities was "sadness." We analyzed 12,179 news stories posted on the four major U.S. newspapers' Facebook pages.

Microbes and their activities have pervasive, remarkably profound and generally positive effects on the functioning, and thus health and well-being, of human beings, the whole of the biological world, and indeed the entire surface of the planet and its atmosphere. Collectively, and to a significant extent in partnership with the sun, microbes are the life support system of the biosphere. This necessitates their due consideration in decisions that are taken by individuals and families in everyday life, as well as by individuals and responsible bodies at all levels and stages of community, national and planetary health assessment, planning, and the formulation of pertinent policies. However, unlike other subjects having a pervasive impact upon humankind, such as financial affairs, health, and transportation, of which there is a widespread understanding, knowledge of relevant microbial activities, how they impact our lives, and how they may be harnessed for the benefit of humankind - microbiology literacy - is lacking in the general population, and in the subsets thereof that constitute the decision makers. Choices involving microbial activity implications are often opaque, and the information available is sometimes biased and usually incomplete, and hence creates considerable uncertainty. As a consequence, even evidence-based 'best' decisions, not infrequently lead to unpredicted, unintended, and sometimes undesired outcomes. We therefore contend that microbiology literacy in society is indispensable for informed personal decisions, as well as for policy development in government and business, and for knowledgeable input of societal stakeholders in such policymaking. An understanding of key microbial activities is as essential for transitioning from childhood to adulthood as some subjects currently taught at school, and must therefore be acquired during general education. Microbiology literacy needs to become part of the world citizen job description. To facilitate the attainment of microbiology literacy in ...
