In this discussion, Brad Littlejohn and Alastair Roberts get to the most fundamental aspect of the crisis now facing us: the epistemic crisis that has made it difficult for many citizens to understand or agree about the nature of the threat that faces us.

How do we deal with problems of uncertainty and probability when the stakes are high, and why do we seem so bad at sorting through these things in an era when we have more access to information than ever before?
