The article discusses the scientific and intellectual origins of collective wisdom in the constitutional, information and digital dimensions, reveals the doctrinal approaches and normative foundations of popular deliberative constitutionalism, the development of an inclusive constitutional paradigm and its significance for the use of procedures and technologies for citizen participation, expert opinion and civil society institutions in the constitutional development, in social transformations, in constitutional changes brought to life by the needs of society and the state. Popular deliberative constitutionalism is identified in the article as a public legal meta-concept that explains the process and need for constitutional involvement of citizens. The author concludes that popular deliberative constitutionalism allows us to better understand the problems of implementing the principle of popular sovereignty in modern democratic states, create an optimal model and consider the forms of exercising the constituent power of the people when implementing constitutional changes. In the article, the author notes that the future of democratic constitutionalism is associated with the creation and use of collective intelligence technologies in the public legal sphere, which, in the context of the development of an algorithmic and information society, combine classical procedures for discussing constitutional issues and the use of aggregated preferences. The practical application of the achievements of natural and artificial intelligence is intended to discuss and resolve issues of public legal significance, is based on co-evolutionary development and leads to the emergence of mini-publics, civil assemblies, and constitutional crowdsourcing.
