Truth vs Lies

How do we navigate the post-truth era, when there is no longer an expectation that politicians or pundits will be honest? In this eBook, we break down the science of deception so that we can protect ourselves against it. We look at human perception and how those perceptions are influenced using technology as well as provide interventions for combating bias and antiscience thinking.
