I have a 40-year background in the principles of social psychology, which is where most of the theory and practice of trial consulting comes from. I’ve been a professor since 1985, teaching social psychology, experimental methods, statistics, psychology of law, and other relevant courses. I have published articles on how to get honest answers about bias in voir dire and in surveys. I am uniquely qualified to perform surveys about juror bias, therefore.


  • 17 years trial consulting experience.  Performed 20 COV surveys and pretrial publicity content analyses. Experience in mock trials, jury selection/voir dire, Colorado Method of juror life qualification.
  • Critiqued change of venue surveys performed by other trial consulting companies, testified in court about errors in their question construction, the statistical analyses they used, and their interpretations of results.
  • Scholarly research on legal psychology issues. For example, on “prehabilitation” (a term coined in Hamilton’s research lab), which refers to judges’ and attorneys’ attempts to rehabilitate before asking prospective jurors about their biases, thereby exerting pressure on them to hide any biases from the court.
    “We’re here to see whether you are able to set aside pretrial publicity.” “Do you think you are capable of being impartial and fair?”
    “Remember, it is your duty to presume innocence. Do you think you can do that?”
