How is emotion shaping the creation and consumption of journalism in the era of mobile, personalised, digital media? This lecture given to the British Science Festival argues that the way that news is shared on social networks is changing the way that it is produced. Journalists are becoming more concerned with using emotion to get attention and traffic for their work. In turn the way that the public finds and shares news depends increasingly on their emotional response to it. This has ethical and political consequences such as the danger of increased fragmentation and relativism and the demise of the aspiration towards objectivity.
