In a post-truth world where more and more people get their news and knowledge from social media or other non-traditional sources, does expertise count anymore? The spread of mobile phones and high-speed internet has enabled unprecedented levels of access to information, but how does one navigate this knowledge maze without the help of experts?To discuss these and other questions, we invited our colleague Dr Anuradha Sajjanhar, who teaches politics and public policy at the University of East Anglia, and one of our talented graduate students, Pham Minh.We talked about a number of things: knowledge production and trust in experts, the role of governments and think-tanks, and the viability of building a more equal, less divided world.We ended our discussion by asking our guests, who both have had experience of being international students, for their advice to potential international students, who comprise a good number of our regular viewers.Dr Anuradha Sajjanhar's professional website: https://anuradhasajjanhar.com---PromotionImmigration into the UK is one of the areas where one cannot do without the help of an experienced expert.
