Are we living in a ‘golden age’ of political conspiracy theories and what does belief in them tell us about voters and politicians? James Tilley, a professor of politics at the University of Oxford, talks to historians, psychologists and political scientists to ask why conspiracy theories are so common and who are the people spreading them. Why are so many of us drawn to the notion of shadowy forces controlling political events? And are conspiracy theories, in which things always happen for a reason and where good is always pitted against evil, simply an exaggerated version of our everyday political thinking?
