You create them. You get a certain number of people who have never played go. You give them a rule book, teach them go problems that get them to a certain level of problem solving competence, and then you use different problems with similar themes, or slightly more complexe (3 move sequences, rather than 2 move answers) sequences to solve in the study itself.
But, I shouldn't be here. I already hijacked the thread once apparently.
