To explore the willingness to participate in genomics research among African Americans, we developed a technique specifically suited to a relaxed social setting. The "Qualitative Story Deck," (QSD) is a gamified, structured elicitation technique that allows for the spontaneous creation of scenarios with variable attributes. We used the…
