  1. Choosing 3 is spot on. The old adage, “pick C” wasn’t a myth. Before we had computers to randomize multiple-choice exams, most instructor-constructed exams had a bias towards C. If you are in a room with a fairly (i.e., n > 25) large audience, ask them to pick a number between 1 and 4 inclusive (if it is a room full of mathematicians, you have to say “pick a natural number…”). The results are very interesting.

  2. This problem seems eminently solvable. First show the witness a page of known innocents, and then proceed to the actual experiment.

      • The first page they see controls for absolute (red in this comic) vs. relative (yellow) witnesses, since the pictures are all from the control group. If the witness rejects that lineup, then they’re good to go on a lineup with the actual suspect (as well as the rest of the control group).
