The constructive use of doubt is central to all of statistical thinking. Being scientific requires that you be skeptical of your own claims and the claims of others. Skepticism is a defence against accepting false, dangerous, or destructive representations of reality which may be comforting and empowering, particulary in desperate or fearful situations. Websites set up by skeptics make good use of doubt (and sometimes statistical experiments and surveys) in order to get a clearer look at the world. Some useful sources of skeptical analyses can be found here:


There are three basic themes to my research.

  1. Developing methods to assess the degree to which large and complex computer models represent any aspect of the scientific, technical, or medical phenomena that motivated their creation.
  2. Constructing spatial statistics that can summarize disorder in systems whose disorder differs greatly from that seen in traditional spatial statistics or traditional statistical physics.
  3. Using ideas from science studies (the history, philosophy, sociology, anthropology, and rhetoric of science) to improve statistical education and practice.
