Gastil’s early research culminated in his 1993 book
Democracy in Small Groups. In it he explored the workings of group decision rules, the establishment and maintenance of democratic norms, and the emergence of deliberative practices. Some of his later research examined the
jury, one of the most important venues through which ordinary citizens can deliberate and make consequential decisions. Building on the insights of
Alexis de Tocqueville and others, Gastil and his coauthors produced in
The Jury and Democracy the first large-scale study of how jury service affects those who participate. Gastil shows the effects on jury members’ civic attitudes, views about legal institutions, opinions about deliberation, and subsequent participation in politics.
The Jury and Democracy won the 2011 Ernest Bormann Research Award from the
National Communication Association. Gastil is also widely credited for promoting deliberation among citizens during elections and in other political institutions. In his book
By Popular Demand, he proposed creating panels of citizens, chosen randomly to ensure a cross-section of society, to deliberate on ballot initiatives and referendums. In 2010 Oregon became the first state to implement this idea through its
Citizens’ Initiative Review (CIR). and the news media. Gastil has testified before the legislatures of Oregon, Washington, and Massachusetts about these deliberative processes. ==Selected publications==
