This is an investigative linguistic blog in which I share some of my ongoing academic research and deception detection training materials. My general intention is to explore the linguistic landscape of the post-truth era. I hope this blog will stimulate discussion and debate, and complement the incredible investigative journalism that is a signature trend of our current times.
