This is part two of an interview with Oliver Boyd-Barrett. This episode of the podcast focuses on the effects of developments in science and technology on our society - and in particular on the science of propaganda. I speak with Professor Oliver Boyd-Barrett from Bowling Green State University about the influence that social media, cyber warfare and hacking, bot armies, troll farms, and other technologies have on the spread of disinformation and misinformation throughout our society. Who is it that really wields power in the world?
