Hot politics lab



POLEMIC is an ERC Starting Grant project run by Gijs Schumacher and conducted in the Hot Politics Lab.

*The project will start April 1st 2018, and will run to 2023.





For three days the Hot Politics Lab measured physiological responses to political propaganda at the Netherlands’ largest music festival – Lowlands. 

The lab was situated in the Lowlands Science area, a small village in which several research groups conducted research. In our experiment, we exposed people to brief videos that advertised a specific position on themes such as immigration, inequality, the environment and the political establishment. During the experiment we measured heartbeat, skin conductance and facial electromyography.



Many claim that politicians make more, and more extreme, emotional appeals than ever before, because these appeals win over the emotional citizen. With highly emotive language people like Donald Trump, Geert Wilders or Marine Le Pen are pounding on the portals to power. Do such emotional appeals affect citizens’ political choices? Yes, they can. But, citizens’ existing emotional attachments to parties, leaders or issues moderate the success of emotional appeals. POLEMIC will extend existing theory and use novel methods to explain when (types of) emotional appeals are persuasive, and when emotional attachments prevent persuasion.

Do politicians actually make more emotional appeals than in the past? And if so why are they doing it? We lack historical data of emotional appeals so we cannot answer these questions. POLEMIC will provide unique, historical data (1945-now, 9 countries) of emotional appeals by politicians in their speeches. I develop and test 3 alternative theories from different intellectual traditions that explain why politicians make emotional appeals: is it either (1) a vote-maximizing strategy, (2) a product of the personality of a politician or (3) just fashionable?

POLEMIC analyses emotional appeals of politicians and the emotional responses of citizens to these appeals. Emotional appeals are texts, and emotions are experiences by the brain. To measure them POLEMIC will use innovative methods in political science: automated text analysis to extract emotion from appeals; physiological measurement to measure emotions.

POLEMIC offers a ground-breaking combination of a macro-perspective (what politicians say) and a micro-perspective (how citizens respond) and forms a bridge between party politics and political psychology. The project’s output will indicate the importance of emotion in the decision-making of citizens, and the level of rationality that is behind politicians’ decision to make emotional appeals.
