On the question of the relationship between Stechiology and the Analytic that seems to have replaced it, note that, in Draft D of Memoir 15 in his 1902 Carnegie Institute application, Peirce said that stechiology, also called grammatica speculativa , amounts to an Erkenntnisslehre , a theory of cognition, provided that that theory is stripped of matter irrelevant and inadmissible in philosophical logic, irrelevant matter such as all truths (for example, the association of ideas) established by psychologists, insofar as the special science of psychology depends on logic, not vice versa.  In that same Carnegie Institute application as in many other places, Peirce treated belief and doubt as issues of philosophical logic apart from psychology.
You can create a mock “crime scene” with a single print from one of your group and time participants while they find a match by examining every single print. Then duplicate another mystery print and your complete database of prints for teams. First, let them take as long as they like to classify the prints, and then time them again to see who can find a match for the mystery print most quickly using their classification system. How do their systems vary and why would some be more efficient than others?.
