Random selection is necessary to create stable meritocratic institutions

Ireland has a Citizens Assembly, which is selected by sortition. Ordinary citizens take time out of their lives to participate when assemblies are formed to examine issues of the day. The assembly receives expert and political testimony and evidence, and then votes and makes recommendations that often lead to country-wide referendums.

The process has been very successful at neutralizing contentious topics. The assembly on abortion showed that a healthy majority consensus could emerge, and led to abortion being legalized in Ireland after a constitutional amendment. The political parties generally support the process because it keeps socially divisive topics out of the main political sphere. Ireland also has relatively little money in politics, limits on donations, a standards in public office commission, independent constituency boundary commissions, a multi-seat proportional representation system, limits on media ownership, and the highest percentage of University educated citizens of any country. All in all it's helped Ireland come a long way from the 80s and 90s, when Ireland was much worse on corruption indexes.
