This chapter starts by summarising an experiment showing how the brain’s emotion circuitry responds to a set of words signalling threat. The main emotion activated in Brexitspeak is fear; the triggers are both linguistic and visual. They include representation of alarming scenarios, and factual misrepresentations capable of causing various negative emotions. The chapter analyses three well-known cases that illustrate such effects. The first is Vote Leave’s propaganda displayed on the side of a red bus: the slogan was an inaccurate statement that could evoke feelings of attachment, resentment and anger. This is also analysed in terms of speech acts, ambiguous and deniable assertions, and lying. The second case, the rightly controversial ‘breaking point’ poster displayed by Leave.EU had the avowed goal of emotion arousal. The visual element is analysed with reference to cognitive image schemas, and their potential for activating fear reactions. The third case, the most effective of the Vote Leave campaign, was crafted in order to prompt the fear of losing agency. This, too, likely activated the brain’s fear circuitry.
